Leaching Behavior of Copper, Zinc and Lead from

Soil samples contaminated with heavy metals such as lead (Pb), copper (Cu) and zinc (Zn) were leached with citric acid solution. A five step-sequential extraction method involving “exchangeable”, “bound to carbonate”, “bound to Fe–Mn oxide”, “bound to organic matter” and “residue” fractions was also carried out to investigate the leaching behavior of Pb, Cu and Zn with

Leaching of Primary Copper Sulfide Ore in Chloride

2018-7-25  In addition, numerous studies showed that leaching of chalcopyrite in chloride media results in higher copper extractions than in sulfate media [16,23,24]. The main reasons are the formation of chloride complexes, which change the electrochemical behavior of chalcopyrite passivation and/or the higher porosity of the mineral surface [8,16,25].

Copper Oxide Ore Leaching Ability and Cementation

One of the Iranian copper deposits that is located east of Iran and also known as a primeval one in that area is Mesgaran Field. Old mining works have been clearly seen in the area. Iran is located on global copper belt and as a result it has numerous potential areas as copper deposits. The purpose of this study is identifying possible potentialities of copper mining in less developed regions
