As new electronic devices come onto the market, significant numbers of old electronic devices are being scrapped. The number of obsolete electronic devices has also been growing.the context of economic, social and environmental feasibility. Electronic waste is largely scrapping metal mixed with other materials. Significant amounts of iron, aluminum, copper and some precious metals such as gold and silver can be found among the metals.This project deals with the experimental results of the leaching of Cu from Printed Circuit Boards PCB from obsolete electronic devices by means of leaching using different combinations of acidic mixtures followed by precipitation. Printed circuit boards were dismantled, cut into small pieces, and fed into a Ball mill. The powder obtained was leached by using the aqueous solutions H 2SO 4, H .gold leaching either using the same process at elevated temperature 4060 C, as patented by the authors, or using a cyanidation process. Copper selective leaching will reduce the gold losses due to a cementa-tion mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the pre-leaching stage.

In thecopper recovery from WPCBs of mobile phones was designed. Keywords copper, metallurgy, leaching, discarded mobile phones Introduction Nowadays, waste of electrical and electronic equipment WEEE such as discarded mobile phones MP, computers or TV sets is one of the worlds fastest-growing problems and needs to be tackled immediately.Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SXEW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20 of all copper produced is produced by this is process.Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.The high-tenor SX1 circuit removes the bulk of the copper, the extraction of 50 gl Cu generating a raffinate containing 80 gl H 2SO 4.SAG Mill overload due to an increase on the ore coarseness, 2.
