Cyanide Leaching Of Gold - mine-engineerDiese Seite übersetzen

It is not used much anymore, because most leaching is heap leaching, carried out in the outdoors, where drip emitters or sprays distribute the cyanide solution to a large structure of gold ore, called a "heap". And while the pile of ore is called a heap, it is not a haphazard pile of rocks.

Diagnostic Leaching for Refractory Gold OresDiese Seite übersetzen

A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory. Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with progressively stronger reagents, producing a qualitative assessment of the gold ...
