Development of Suitable Reagents was Vital Key: Solvent extraction techniques were first applied to the recovery of metals for atomic energy projects in the decade 1945-55.They were subsequently applied to the large scale production of such refractory metals as hafnium and zirconium.
Although the first large-scale application of copper recovery by solvent extraction (SX) took place in Zambia in the early 1970s, it is only in the last decade that this technology has become widely employed in this part of the world and is now a mainstay unit operation in most copper hydrometallurgical flowsheets.
An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
earth. The majority of proposed mining projects involve the extraction of ore deposits such as 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
With large amounts of water used for mine drainage, mine cooling, aqueous extraction and other mining processes, increases the potential for these chemicals to contaminate ground and surface water. As mining produces copious amounts of waste water, disposal methods are limited due to contaminates within the waste water.
Modern biomining processes are large-scale operations that involve the mining of ores and processing for several months (Fig. 1). Either through strip-mining or blasting, raw ore is obtained for extraction of copper.
