Abstract

The invention belongs to the field of metal mineral separation and provides a combined collecting agent for improving production index of carbonous gold ore and application of the combined collectingagent in floatation of carbonous gold ore thereof. The combined collecting agent comprises, by weight, 3-6 parts of a collecting agent J-622, 2-3 parts of ammonium dibutyl dithiophosphate, 0.5-1 partof kerosene and 0.5-1 part of octaphenyl polyoxyethyiene (OP)-10. The floatation comprises the steps that ore grinding is conducted first; sodium hydroxide as a regulator and MFA as a water purifyingagent are added, and size mixing is conducted; an activator and a collecting agent are added, rapid floatation is conducted, and concentrated gold ore 1 and roughing tailings are acquired; regrindingis conducted on the roughing tailings, and the water purifying agent, MFA, is added when regrinding is conducted; and then floatation is conducted, and concentrated gold ore 2 and tailings are acquired. The concentrated gold ore 1 and the concentrated gold ore 2 serve as qualified concentrated gold ore products. According to the combined collecting agent, the aid-dispersion mechanism is utilized;dissolution dispersity of medicament in an ore pulp is increased; consumption of the collecting agent is reduced by a large margin; collecting capacity of gold is improved greatly; the cost of medicament is lowered; and economic benefits of enterprise production is improved.

Description

technical field [0001] The invention belongs to the technical field of metal beneficiation and relates to a collector for flotation, in particular to a combined collector for improving the production index of carbon-containing gold ore and its flotation application. Background technique [0002] Carbon-bearing gold ore is a refractory ore, mainly because it is often difficult to obtain ideal results through conventional flotation agents. At present, there are many collectors for carbon-bearing gold ore separation, but conventional single collectors have problems such as poor separation effect, high chemical consumption, high beneficiation cost, and poor separation effect. Some combined collectors have stable Poor performance, difficult to disperse in pulp. In addition, in the actual production on site, carbon, as the carrier of gold, often absorbs a certain amount of gold and enters the overflow of the thickener, which not only causes a low recovery rate of gold, but also d...
