Solution mining of copper replicates a natural process of dissolution and reprecipitation that has occurred for millions of years and continues today. Known as supergene enrichment, this natural process has been observed at many of the world’s copper deposits. It occurs when hypogene (i.e. primary) ores, containing sulfide minerals such as pyrite (FeS 2), chalcopyrite (CuFeS 2) and bornite

By the turn of the twentieth century, converters were added to the process. A copper sulphide ore might go through four different kinds of furnaces for roasting, matte smelting, converting and refining before it was recognisable as copper metal. Later, electrolytic plants replaced furnaces for refining. 3 When base metal mining commenced in Australia in the 1840s, Cornwall was the principal

Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 1 % Cu) must be concentrated by beneficiation. The valuable minerals

copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium. The Guidebook also does not discuss mining

The Smelting of Copper The first written account of the processes of smelting and refining of copper is to be found in the 12th century.1 On smelting: Copper is engendered in the earth. When a vein of which is found, it is acquired with the greatest labour by digging and breaking. It is a stone of a green colour and most hard, and naturally mixed with lead. This stone, dug up in abundance, is

The mining sector, specifically, the copper mining industry, is essential to Chile's economic and social development. Mining contributes significantly to national income, tax revenue, jobs and business opportunities, and, ultimately, the country's growth. Given its importance, the Government has requested us to review the evolution of pro-ductivity in the Chilean Copper Mining Industry, and

mines is presented, together with a discussion of the main variables involved in the process. Overview of current copper mining Copper has been used by man since ancient times. It is thought that already in the Stone Age, over 90,000 years ago, copper had domestic, hunting and war applications. In those days copper was found in elemental state with relative abundance, but around 5,300 BC

Copper and battery metals, which stand to gain as the energy mix moves away from combustion engines to electricity including renewable energy, are receiving the bulk of capital investment. (However, as coal contributes 38% to global electricity generation, it remains an important part of the basket and continues to receive substantial capital investment and transaction focus.)

DRC) is well known for copper mining since the first discoveries of copper in the early years of the twentieth century, and significant smelting and refining operations can be found in this area, including those at Nchanga, Mufulira and Nkana. The Copperbelt is also one of the major cobalt mining areas of the world, although electrolytic cobalt made an impact somewhat later than copper, with

compatible with the copper leaching process because it did not extract copper below pH~36. Technically this problem could be solved by neutralizing the acid leach liquor or by leaching oxide copper with ammonia, but neither solution was economical. a molecule that extracted copper well from typical dump leach liquors (pH ~1.8) had to be built. The reagent LIX 64, containing the ketoxime LIX
