Flotation Process Gold Ore

Separation efficiency improvement of a low grade copper

Sandy Desert in the Paterson Province of Western Australia, processes low grade copper-gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold is recovered both as a

Mineralogical factors affecting the extraction of gold in

ores using gravity, flotation, cyanidation or a combination of these processes. For refractory gold ore processing, pretreatment technologies, such as fine-grinding, autoclaving, roasting and biooxidation will also be required. The reason for using different process flowsheet is mainly because gold often occurs in different forms and minerals, and each ore has to be treated differently

Gold Tailings Reprocessing Technology

The processing technology uses one-stage grinding, preferential flotation process. The gold and copper concentrate product can be recovered once. In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity

Improved recovery of a low-grade refractory gold

01.07.2014· In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.

Extraction of Gold from a Low-Grade Double

The treatment process of a low-grade refractory gold ore containing sulfide minerals and carbonaceous matters was studied in this work. The gold extraction of this ore by all-sliming cyanidation was only 11.75%. Hence, a pretreatment was necessary. In this paper, a flotation-preoxidation-cyanide leaching process was developed. The concentrate from the flotation procedure was processed using
