gold dressing process - jinpeng mining. Gold dressing process. Gold content is very low in ore. To extract gold, need crush and grind ore and use mineral processing technology to pre concentrate or separate gold. For gold dressing, the gravity separation, flotation and cyaniding are widely used. The CIL are widely used in Africa
Non-cyanide gold leaching agent (also can be called Non-cyanide gold dressing agent or Non-cyanide gold dissolving agent) is mainly applicable to heap leaching, tank leaching, and carbon paste (agitation leaching) processes of fine grind gold and silver ore.

Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm. Gold occurs predominantly in native form in silicate veins, alluvial and placer deposits or encapsulated in sulfides. The recovery of gold from gold-bearing ores depends largely on the nature of the deposit.
The method comprises introducing mixed potassium ferrocyanide and urea into a reactor, adding pH adjusting agent while being subjected to slow heating, and in molten state, a small amount of melts...
