Copper mines

Concentrates

ELENILTO MINERALS & MINING owns gold, copper, iron ore, chrome, titanium, bauxite, manganese and other minerals exploration and mining licenses in Africa and Europe and has a more than 100 exploration and mining projects with over 10,000,000 sq.m. for Copper and other minerals in Tanzania, Ghana, Liberia and Albania varying stages of progress, several of which are highly prospective for significant economical ore deposits.

Mineral concentrates are the intermediate form of mostly metallurgical feed-stock going into the final stages of processing and refining, yielding the metallic products.

Engelinvest Group is investing in the exploration and production of various industrial metals with new mines and projects expected to boost output by 2009-2010. At the first stage the following copper & Chrome concentrates will be produced and handled.

Copper Concentrates

The majority of the copper mineralization is combined with sulphure in the form of sulphides. These ores are mined, crushed, ground down to the mineral liberating size and then concentrated by flotation. The concentrates carry mostly 25-35% copper and are being traded and shipped worldwide to copper smelters for further processing and manufacture of electro-refined copper and co-products which accompany the copper mineralization, for instance, precious metals and cobalt. Copper mineralization could occur, in some cases, in a naturally concentrated form, sometimes partly or completely oxidized, and following a selective mining operation, could also be shipped as such. Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process,

beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores. Copper is one of the oldest metals ever used and has been one of the important materials in the development of civilization. Because of its properties, singularly or in combination, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminum in terms of quantities consumed. Electrical uses of copper, including power transmission and generation, building wiring, telecommunication, and electrical and electronic products, account for about three quarters of total copper use. Building construction is the single largest market, followed by electronics and electronic products, transportation, industrial machinery, and consumer and general products. Copper byproducts from manufacturing and obsolete copper products are readily recycled and contribute significantly to copper supply.

Copper and copper-based alloys are used in a variety of applications that are necessary for a reasonable standard of living. Its continued production and use is essential for society's development. How society exploits and uses its resources, while ensuring that tomorrow's needs are not compromised, is an important factor in ensuring society's sustainable development. The demand for copper will continue to be met by the discovery of new deposits, technological improvements, efficient design, and by taking advantage of the renewable nature of copper through reuse and recycling. As well, competition between materials, and supply and demand principles, contribute to ensuring that materials are used efficiently and effectively.

Copper is an important contributor to the national economies of mature, newly developed and developing countries. Mining, processing, recycling and the transformation of metal into a multitude of products creates jobs and generates wealth. These activities contribute to building and maintaining a country's infrastructure, and create trade and investment opportunities. This is particularly important for lesser-developed countries seeking to improve their living standards.
