Gold Extraction Processing Line

Comparison of the CIP gold extraction and Field Production

Gold mine site production of the original ore after crushing, Sec two closed-circuit grinding, flotation gold concentrate after the Sec cyanide leaching, and then with zinc dust replaced from the cyanidation your solution, gold extraction, beneficiation methods. The metal mineral recovery in about 88%. The production process is relatively complex and high cost.

Cyanide leaching process includes pressure filtration, cyanide and replacement of more than one section. The basic process is gold concentrate flotation in Φ12 m thickener dewatering, after pressure filtration tune paddle into the first paragraph of cyanide (5 leaching tank), the end of a dip after another Φ12 m thick machine dehydration into the second paragraph cyaniding (of two leaching tank), Second Baptist tail after a three-tier Φ9 m washing machine washing and after pressure filtration mashing into the copper flotation recovery operation, the new 12m and 9m overflow flow out(ie cyanide expensive liquid), then after deoxidation and filter into the replacement job.

In contrast, the CIP gold extraction process flow uses less equipment and floor space.The production process is relatively simple. From the view of metal recovery and production costs, it has obvious advantages.The CIP gold extraction method field practice, the total raw ore processing 1200 t, the calculation of the theoretical amount of metal ore grade over the same period of 5.45 kg. Actual smelting gold 4.95 g, 90.8% metal recovery.

CIP gold extraction production process advantages

From the field practice with the same period by the CIP gold extraction process on-site production indicators contrast, we found that the original gold CIP extraction processing has very broad prospects. The metal recovery increased from 89% to 90.5%.

In addition,considering the cost and process of production,the CIP gold extraction process has obvious advantages,such as the...
