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.

    The invention relates to amethodfor producingcopperin ahydrometallurgical processfromcopper-bearing raw materials, such as sulfidic concentrates. The concentrate is leached in a leaching stage of several steps into a chloride-based solution. Thecopper-bearing solution obtained from this leaching is subjected to reduction and solution purification, whereafter thecoppercontained in the ...

    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.

    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.

    Pyrometallurgical processes resulted in the formation of approximately 3.4 t of SO 2 for every 1 t of copper. The hydrometallurgical process includedpressure leaching under slightly oxidising conditionsindiluted sulphuric acid(at 80–105 °C and 140-350 kPa oxygen pressure). This enabled selective extraction of up to 97% of copper, with less than 10% of pyrite taking part in the reaction.

    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 ...

    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.
