Abstract

The invention relates to a novel environment-friendly composite collector for gold ore dressing. This novel environment-friendly composite gold beneficiation collector comprises the following components: 35-45 parts of the main collector, 20-35 parts of the secondary collector, and 15-20 parts of water; wherein, the main collector consists of the following weight Raw material composition in parts: 45‑50 parts of dihydrocarbyl dithiophosphate, 20‑28 parts of isooctyl mercaptoacetate, 8‑12 parts of thiourethane, 5‑9 parts of sodium oleate, dihydrocarbyl thionocarbamate 8-10 parts of acid ester; the secondary collector consists of the following raw materials in parts by weight: 30-35 parts of alkyl hydroxamic acid, 26-28 parts of polyacrylamide, 10-15 parts of isooctyl phosphate. The new environment-friendly composite gold mineral processing collector of the present invention has the characteristics of strong collecting ability, good selectivity, small dosage and foaming for gold minerals, and effectively solves the problem of low recovery rate of fine-grained and fine-grained gold. And the problems of easy loss of fine-grained gold and low recovery rate of gold-sulfur separation during the separation of gold with high sulfur content.

Description

technical field [0001] The invention relates to an 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 refracto...
