Heap leaching - Wikipedia

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 ...

How Does Heap Leaching Agglomeration Work

Agglomeration means that the clays and fine particles contained in the ore adhere to the coarser particles and create a coating of fines around the coarse particles. When the ore has few fines and the percolation problems are not severe, the addition of a liquid may be all that is necessary to render the fines immobile in a heap. When the quantity of fines is substantial, e.g. 10% -200 mesh, a ...
