Abstract

The invention relates to a novel environment-friendly composite gold ore dressing collector. The novel environment-friendly composite gold ore dressing collector comprises, by weight, the following components: 35-45 parts of a main collector, 20-35 parts of an auxiliary collector and 15-20 parts of water; wherein the main collector comprises, by weight, the following raw materials: 45-50 parts ofdihydrocarbyl dithiophosphate, 20-28 parts of isooctyl thioglycolate, 8-12 parts of thiourethane, 5-9 parts of sodium oleate and 8-10 parts of dihydrocarbyl thiocarbonyl carbamate; the auxiliary collector comprises, by weight, the following raw materials: 30-35 parts of alkyl hydroxamic acid, 26-28 parts of polyacrylamide and 10-15 parts of isooctanol phosphate. The novel environment-friendly composite gold ore dressing collector has the advantages of strong collecting capacity, good selectivity, small dosage and foaming property for gold ore, and effectively solves the problems that the ore dressing recovery rate of fine grains and micro fine grains is low, the fine-grained gold is easy to lose when gold with high sulfur content is separated, and the gold-sulfur separation recovery rate is low.

Description

technical field [0001] The invention relates to a novel environment-friendly composite gold beneficiation collector, which belongs to the technical field of nonferrous metal mining. Background technique [0002] Flotation is the most widely used mineral comprehensive recovery technology. In principle, it can separate various minerals. It is a high-efficiency "separation process". Most gold ore dressings in the world are recovered by flotation. The flotation process Collectors are usually added to improve gold recovery. [0003] Gold ore resources are important mineral resources. With the increasing demand, the easy-to-handle gold ore resources are getting less and less, while the refractory gold ore resources are getting more and more attention. Refractory gold ore resources mainly include carbon-bearing gold ore, fine-grained embedded gold ore, gold-bearing polymetallic sulfide ore, and arsenic-containing gold sulfide ore. For the fine-grained embedded gold ore in the ref...
