Hello Folks! Welcome to Our Blog.

At present, the ore is still being mined only at Awaso even though major bauxite deposits occur at Kibi, Nyinahin and Ejuanema. The main objective of the MOU is the development of an integrated aluminium industry in the country.

Industry Structure Aluminium has one of the most complex processing chains of all metals, with four major production steps leading from the raw material bauxite to raw aluminium sheets and profiles. The major steps in aluminium processing are.

The processed aluminium is the input for aluminium goods ranging from packaging material, automotive parts and construction elements to household goods. Worldwide, 10 vertically integrated global companies dominate about 70 percent of the global production capacity.

The key success factor in the aluminium industry is low cost production, which requires access to different sources of input material, mainly bauxite and electricity across the globe. The complexity of the production process and the importance of having access to the right resources are the main reasons for persistent vertical integration across the industry.

Ghana is home of almost all major production steps in aluminium processing, but not in an integrated form. Aluworks is the only company that processes or casts aluminium ingots in Ghana and provides one of the vital links in the chain in aluminium processing in the country. The Commission is specifically required by law to carry out the following functions:. Formulate recommendations of national policy for exploration and exploitation of mineral resources with special reference to establishing national priorities having due regard to the national economy and advise the Minister on matters relating to minerals.

Secure a firm basis of comprehensive data collection on national mineral resources and the technologies of exploration and exploitation for national decision making. The construction of the smelter was started in and started smelting aluminium in with three pot lines in operation. Currently, the plant boasts of five pot lines which ought to work all day throughout the year with a production capacity of two hundred thousand tonstones primary aluminium per annum.

It shut down intermittently for various reasons mainly due to power related issues until early when it was completely shut again. It imports processed alumina from the international market to produce aluminium, a majority of which is exported.

Aluworks Limited — Aluworks is an aluminium continuous casting and cold rolling mill located in Tema, the major seaport and industrial city in Ghana. Aluworks provides one of the vital links in the chain towards complete integration of the industry in Ghana. The company produces flat rolled aluminium products for roofing sheets for the building and fabrication sector and is the main input supplier to hollowware manufacturers.

The largest volume of aluminium is used in the manufacture of extruded profiles for doors, door handles, window frames, curtain rails, corrugated roofing sheets, etc. The building industry is expected to achieve even more growth and as such an increasing need for aluminium products is expected. Hollowware Manufacturers — The aluminium hollowware sector is highly competitive and includes a large number of competitors with Pioneer Kitchenware Limited, Domod Company Limited and Lion Aluminium Products amongst the main competitors in this area of production.

The growth of this market has been very consistent and strong. Most of the companies in this market purchase the bulk of their raw material, aluminium circles from Aluworks: although some are supplied through foreign sources.Ghana Bauxite Company Ltd operates an open cast bauxite mine at Awaso in the western region of Ghana. The facility consists of a 4 m high embankment built across a valley on a silty sandy gravel foundation. Seepage forces and pore pressures in the foundation and embankment have raised some stability concerns.

The principal objective of this study is to carry out an assessment of the stability of the water storage facility embankment and foundation and propose measures to improve it. The stability assessment procedures include: a investigating the geological, geotechnical and engineering properties of the embankment and foundation material, b evaluating possible failure factors such as piping, erosion, sliding and seepage; and c reviewing operational parameters of the facility.

From the qualitative and quantitative assessments, it was concluded that the embankment of the facility was susceptible to failure resulting from inadequate compaction, seepages and overgrown tree roots. The foundation, on the other hand, was found to be susceptible to failure resulting from seepages.

Recommendations for improving the embankment integrity include the construction of a toe drain, implementation of a vegetation cover management scheme and documented periodic monitoring. Open PDF.

History of Bauxite in Ghana First discovered in in Ghana by Sir Albert Kitson, bauxite is an ore and the main source of aluminium. Ghana has substantial deposits of bauxite in regions of Ejuanema, Nyinahin, and Kibi, though most of them remain unexploited with mining activities mainly undertaken in Awaso. Ghana was allowed as a member of the International Bauxite Association in November Ghana Bauxite Company has been working on the mining site in Awaso sincewhich is said to have enough reserves to last for more than three decades.

Other bauxite reserves of Ghana are said to have reserves to last for more than a century. Effect of Bauxite Mining on Local Communities Mining is one of the largest economic activities in Ghana, apart from farming.

As mining sites are usually remote, companies have had to make huge investments in building infrastructure such as schools, roads, electricity and water supply and hospitals that have helped communities situated close to these locations. However, due to the degradation of air, water and the environment due to mining activities, these communities have also been suffering. Government policies have failed to protect people and communities from the negative impact of mining, which has worsened the poverty levels of the country.

The Present Scenario There are large reserves of bauxite in Ghana; however, those have not been exploited to their fullest potential, with just half of its capacity being mined. Moreover, there have been major reductions in the amount of bauxite that has been shipped from Ghana.

The Western Rail Lines of Ghana are in a deplorable condition that is leading to heavy losses for the company over the past few years as it continues to use the more expensive mode, roads, to carry the ore to the port. Ghana has significant potential to increase and expand bauxite extraction, as it has a rich source of hydro-electricity. Hydro-electricity is relatively cheap as well, which can be utilised to smelt aluminium. A recent study on bauxite mining in Ghana has also recommended that the government should make it compulsory for companies to set up a refinery plant, if they wish to pursue mining of bauxite.

Though Ghana is one of the largest exporters of bauxite, it fails to achieve the expected returns for the local economy, which if met could help the country and its people develop.

In general, the types of household goods manufactured in Ghana are not produced in developed countries. In the domestic market, closeness to the input material and low transportation costs result in a very cost-competitive position for the local industry.

Exports to neighbouring countries however are in strong competition with goods from East Asia and other African countries. Production can be compromised due to the under-utilization of plants and equipment.

The survival of the industry hinges on the guarantee of a continuous supply of energy. The bauxite is transported over km on a single-track railway, which is also used for manganese, timber, and cocoa loads. Information infrastructure Although the aluminium industry as a whole is a very important industry for Ghana, there is no government or industry-sponsored research or training institutions providing specific support for the industry. Quality AssuranceThe region has about 75 per cent of its vegetation within the high forest zone of Ghana, and lies in the equatorial climatic zone that is characterized by moderate temperatures.

It is also the wettest part of Ghana with an average rainfall of 1,mm per annum. The population of the region is 1, constituting about 10 per cent of the total population of the country. With a population growth rate of 3.

The population is relatively young, with over 40 per cent within the age groupand a dependency ratio of The population density is Females constitute The proportion of urban to total population is There are five major indigenous ethnic groups, namely, the Ahantas, who form 6. It is worth noting that The Pentecostals constitute the largest single Christian group Other Christian groups constitute another Islam 8.

Traditional African religion is also practised by 1. The level of literacy in the region is Nearly two-thirds There is therefore a very high attrition rate between primary and junior secondary school levels.

Several reasons account for the high dropout during the transition from primary to junior secondary. These include the unavailability of junior secondary schools within many rural localities, resulting in pupils having to travel 10 kilometres or more to the nearest junior secondary school.

Other important factors are affordability and poor infra-structural facilities. In recent years, however, there has been a tremendous effort to improve both quality and quantity of infrastructural facilities of primary and junior secondary schools. The number of houses in the region isas at More than half of the houses belong to household members who either rent them out to paying tenants, or permit family members to live in them without any charge.

Most houses, particularly in the rural areas, are constructed with sun-dried mud bricks with cemented floors and corrugated metal roofing materials. There arehouseholds in the region, which gives an average of 1.

Of these 72 per cent are male-headed as against 28 per cent headed by females. The number of persons per household is 4. Many households in the urban areas have access to electricity, while a relatively small but significant number of rural households are gradually gaining access through the rural electrification programme. Those without electricity use mainly kerosene as lighting fuel. Fuel for cooking is mainly charcoal and firewood, even though liquid petroleum gas and electricity are used by some urban dwellers.

Potable water, either treated pipe-borne water or water from deep boreholes, is available mainly in urban areas. The rural areas obtain water mainly from rivers, streams, small lakes, springs and shallow hand-dug wells. Potable water is however gradually being made available to rural communities through the sinking of deep boreholes.

Marriages are either formal or informal unions. Those in such marriages constitute There are more divorced and widowed females than males.

The greater proportion of widowed females is due probably to females normally marrying older males who then die earlier and leave them widowed. Widowed females tend generally not to remarry while widowed males generally remarry. The region is endowed with considerable natural resources, which give it a significant economic importance within the context of national development.Important mineral deposits.

The major metallic minerals of Ghana are gold, bauxite, iron and manganese. At present, gold, bauxite and manganese are being mined in Ghana.

Gold: There is great potential of gold exploration in Ghana. It is the main focus of majority of foreign and local exploration companies in the country. Bauxite: Ghana has large deposits of good quality bauxite in the Western, Eastern and Ashanti regions.

Iron: There are three main iron ore deposits in Ghana. These are: Shieni, Oppong Mansi and Pudo. Manganese: There are two types of manganese ores which occur in Ghana. These are oxides and carbonate. The major deposits are at Nsuta in the Western region. These are mainly mined from the Birim and the Bonza diamond fields. Diamonds found in Ghana are found in alluvial gravel.

More than 11 million carats of proven and probable reserves are located about seventy miles North-west of Accra.

50.4 MINERAL DEPOSITS IN GHANA

Currently one million carats of diamonds is produced in a year. Ghana is 9th largest producer of diamonds in the world. Limestone CaCO 3. There are four limestone deposits in Ghana. The main dolomite deposit is located at Buipe-Baka area in the Northern region. Solar Salt. Ghana possesses one of the largest proven renewable solar salt production potential along the entire coastline stretching over a distance of over km.
