Abstract

The invention relates to a gold ore flotation collecting agent and a preparation method thereof. The collecting agent comprises the following components in parts by weight: 25-35 parts of mercaptobenzothiazole, 5-10 parts of dibutyl ammonium dithiophosphate, 3.3-6 parts of an auxiliary agent and 55-60 parts of a solvent. The problems that a single agent is poor in gold selectivity and weak in collecting capacity are solved, and the problem that the ore dressing recovery rate of fine-grain and micro-fine-grain gold is low is effectively solved. The gold ore collecting agent has the advantages of being good in selectivity, high in collecting capacity and the like, and a good flotation effect can be achieved with a small dosage in the roughing process. The method has the advantages of wide raw material sources and simple preparation process.

Description

technical field [0001] The invention relates to the field of flotation, in particular to a gold ore flotation collector and a preparation method thereof. Background technique [0002] At present, most gold ore beneficiation is recovered by flotation, and xanthate collectors are usually used in the flotation process to recover gold minerals. [0003] For example, CN102049355A discloses a high-carbon and low-sulfur gold ore flotation agent and a flotation method thereof. Flotation agents include activators, regulators, foaming agents and collectors. The flotation method is to pulverize and grind the high-carbon and low-sulfur gold ore to -200 mesh, and then add activator, regulator, foaming agent, and collector in turn after pulping, and stir evenly; the gold concentrate and Rough separation tailings, gold concentrate is selected to obtain gold fine powder and concentrated tailings, rough separation tailings are swept to obtain scavenging gold ore and tailings, tailings are ...
