Leaching in Metallurgy and Metal Recovery emewCorporation. Jul 10, 2017 · Leaching in Metallurgy and Metal Recovery. ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching. One example of a leaching process that uses vat leaching is gold cyanidation, the process of extracting gold from lowgrade ores.

Without agglomeration, fine particles travel through the heap, clogging the spaces between the larger particles and resulting in poor leach solution flow. Poor flow of leach solution will result in long leach rates and/or decreased metal recovery. Agglomeration immobilizes the fine particles and therefore improves heap permeability to fluid flow.

Agglomeration heap leaching of precious metals.

This paper describes a particle agglomeration technique to improve the flow of leaching solution through heaps of lowgrade goldsilver ores that contain clays. Benchscale experiments and industrial practice have shown that the percolation rate of cyanide leaching solution is greatly enhanced by mixing the ore with portland cement as a binder, moistening the mixture, mechanically tumbling it to

Tank vs. vat leaching

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Heap leaching is generally used to recover gold from lowgrade ore, while tank leaching is used for higher grade ore. Cyanidation is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore, which may or may not have required extensive preparation prior to leaching. Gold and silver are
