hydrometallurgical modern copper processing methods

Hydrometallurgical copper recovery can be conveniently considered in two stages: theleaching stage, in which the various forms of copper in the ore are placed into anaqueous solution, and the recovery stage, wheredissolved copperis recovered as solid, nearlypure copper metal ready for fabrication or final smelting.

    An outline of a hydrometallurgical method employed for the processing of acopper sulphide concentrateis presented. It consists in leaching the concentrate with acid ferric sulphate solution, followed by electrolysis of the copper with simultaneous anodic regeneration of the leaching agent in electrolysers with diaphragms.

    Solvent Extraction Process SX: Hydrometallurgical

    In recent years, the principle and theory behind solvent extraction has gained wide acceptance as one of the new tools ofmodernhydro-metallurgy. With the growing demand for metals of ever higher purity, the increasing use of unusual metals, and the necessity for treating ores of lower grade and greater complexity, solvent extraction has joined the ranks of other accepted recoverymethodsand ...

    Recovering Copper Metal from Leach Liquors. There have been many processes brought out for removing copper from solutions containing that metal, and some of these may find application in special cases, but there are only two which have met with extended commercial use—precipitation by means of metallic iron, and deposition by the electric current.

    Modern coppersmelters use processedcopperore fed into a flash furnace, typically fired by oxygen which produces blistercopper, being further processed in a converter furnace. Moltencopperis poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity.Coppercan be recycled indefinitely without the base metal being compromised ...

    From Ore to Finished Product Copper

    Copper- From Beginning to End.Copperis a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

    The early development ofcopperprobably was most advanced in Egypt.As early as 5000 bce,copperweapons and implements were left in graves for the use of the dead.Definite records have been found of the working ofcoppermines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.
