Heap leaching forms part of the group of technologies known as percolation leaching, which includes in situ leaching, dump leaching, heap leaching and vat leaching bartlett, 1998, john, 2011ommon to all these technologies is migration of leach solution through a fixed bed of ore particles, on its path interacting with the solid, releasing.

HEAP LEACHING TECHNIQUE in MINING

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

The slurry then enters vat leaching tanks and moves to solvent extraction through dewatering. Heap leaching starts with the sprinkling of a low concentration sulfuric acid and water solution on a stockpile (leach pad) of low-grade ore. The liquid percolates through the stockpile and dissolves copper minerals, producing an approx. 60% copper ...

Vat leaching | industrial process | Britannica

This invention relates to a process whereby recovery of copper from copper ores using leaching and solvent extraction techniques can be increased. The process generally comprises leaching to obtain a pregnant leach liquor, washing ore residues with an extra quantity of water to obtain extra dissolved copper values, recovering said copper values, combining the extra wash water with the pregnant ...

The five basic leaching reactor configurations are in-situ, heap, vat, tank and autoclave. In-situ leaching. In-situ leaching is also called "solution mining." This process initially involves drilling of holes into the ore deposit. Explosives or hydraulic fracturing are used to create open pathways within the deposit for solution to penetrate ...

Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak ...
