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 ...

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining

Cyanide Leaching Of GoldDiese 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.

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching .
