dissolution of copper were investigated to know the feasibility of the process 2 Experiment Materials Copper concentrate produced from copper molybdenum ore in Erdenet mining plant Mongolia using flotation was used in this study The most frequent size fraction of the concentrate is to μm with about 49% distribution
the first large scale copper SX plant in the world commissioned in 1974 Despite the equipment design now being outdated this plant still continues to operate successfully indicating the versatility and adaptability of this technology Today there are some 75 copper SX operations worldwide with cathode production above 10 kt/a
The Sepon copper plant has started up successfully in March of 2005 The initial plant capacity is set for 60 000 tpa of copper The autoclave oxidation of pyrite/sulfur will provide virtually all acid and ferric sulfate and heat required for the copper leaching process
4 Copper processing is a complicated process that begins with mining of the ore less than 1% copper and ends with sheets of % pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy
The complete copper pressure leaching process concept includes pressure leaching in an autoclave to produce copper containing pregnant leach solution Leaching is followed by a neutralization step and then copper solvent extraction and electrowinning Gold and silver can be recovered by adding a lime boil step before cyanide leaching
The model equation derived using Minitab predicts that copper leaching efficiency can reach % at optimal values of M sulfuric acid L/S ratio of 100 1 and a leaching time of 80 min
