Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
Percolation Heap leaching, (see Mular et al. pp. 1571–1630, loc. cit.) is very widely applied to the ores of copper and precious metals, but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors. In the heap leaching of low-grade oxidized gold ores, for instance, a dilute alkaline solution of sodium cyanide is distributed over a heap of ...

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 extraction/electrowinning).
As for hydrometallurgy of copper anode slime, the process is relatively flexible and smelters adjusts the process as per the characteristics of the raw material. Whereas the lead anode slime is firstly treated with chloride leaching and then the leaching residue can be mixed with de-selenium and de-coppered copper anode slime for further recovery.
In this paper, a novel process to produce copper from ground and concentrated printed circuit board (PCB) powder is presented. In this process, a powder sample containing approximately 48% copper and 40% other metals, as well as 12% non-metallic materials, was anodically dissolved in an acidic copper sulfate solution, while copper ions were simultaneously reduced on the cathode, …

The CESL Process (Figure 1) involves oxidation of sulphide concentrates at elevated pressure and temperature in the presence of catalytic chloride ions. This is performed within an autoclave. The oxidized copper forms basic copper sulphate (BCS), which is an acid soluble solid.
The use of copper equipment during the prefermentation and fermentation steps typically result in some leaching of copper. Because copper is an essential nutrient for yeast growth, low levels of copper are metabolized by the yeast during fermentation. However, studies have shown that copper levels above 0.2 mg/L are toxic or lethal to the yeast.

copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. . Need for Hydrometallurgical Processes
The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline. The second process, heap and dump leaching of low-
The use of sulfuric acid in an acid leaching process is a conventional method for recovery of copper, but in some cases it is necessary to use other reactants such as ammonia. Ammonia has been known as an effective leaching agent in hydrometallurgical procedures, although it has been less studied than the chemical agents used in leaching.
Heap leaching: It refers to a process which extracts uranium, copper and many other precious metals from their ores. In-situ leaching: It is a process which recovers uranium and copper. Tank leaching and vat leaching: They are the processes in which the ores are to be placed in vats or large tanks that consist of the leaching solutions.
Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations.
