Pre-treatment of refractory gold ore

Pre-treatment of refractory gold ore is aimed at free the gold from occluding of sulfide minerals and so on, which making it difficult for the leaching or flotation solution. Now there are several method to do pre-treat, Roasting, Bio-oxidation or Bacterial oxidation, Pressure oxidation, Chemical Oxidation and so on. By using those method, so that the other mineral composition in refractory gold ore can be effective separated out, which can increased the gold recovery rate in the following process.

Gold Flotation & CIP processing

Gold Flotation Process is use to process fine gold, sulfide gold-containing quartz ore, multi metal gold-containing sulfide ore and carbon-containing ore. Xinhai flotation cell has world class quality, lower price, which is worth your trust.

There are two kinds of ore suitable for gold CIP production line: flotation gold concentrate, amalgamation and gravity tailings; mudded oxidized ore. This method adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon regeneration, leaching pulp. By using Leaching Agitation Tank and Desorption Electrolysis System produced by Xinhai can efficiently recover the gold from ore and get high recovery rate.
