Problems solved by technology

[0002] In the prior art, a single flotation collector is often used in the flotation of sulfide ores. With the change and complexity of the ore, the single drug is gradually replaced by the compound drug that adds multiple collectors at the same time. The purpose is to use the synergistic collection of minerals to achieve a better mineral recovery rate and the desired concentrate grade. Although the compound drug improves the collection and selectivity of minerals, it increases the difficulty and difficulty of dosing. Controllability, high cost of medicine, complicated medicine

Abstract

The invention provides a composite collecting agent for sulphide ore and a preparing method thereof. The composite collecting agent comprises 10-15% of dialkyl monothiophosphate, 15-30% of alkyl monothioformate, 15-40% of dialkyl dithiophosphate, 5-10% of cosolvent, 13-15% of dialkyl dithiocarbamate and 10-20% of water. The composite collecting agent has the advantages that in use, the usage amount is small, cost is low, and the agents are added conveniently; the recovery indexes of metallic copper, gold, silver and the like are improved well; the composite collecting agent has composite action, collecting performance and foaming characteristic in the flotation process, also has the good selectivity and a superior collecting function for useful metal in clay-contained minerals, and can comprehensively recycle the useful metal minerals from complex minerals.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a composite collector for sulfide ore and a preparation method thereof. Background technique [0002] In the prior art, a single flotation collector is often used in the flotation of sulfide ores. With the change and complexity of the ore, the single drug is gradually replaced by the compound drug that adds multiple collectors at the same time. The purpose is to use the synergistic collection of minerals to achieve a better mineral recovery rate and the desired concentrate grade. Although the compound drug improves the collection and selectivity of minerals, it increases the difficulty and difficulty of dosing. Controllability, the cost of the medicament is relatively high, and the medication is complicated. Contents of the invention [0003] In order to solve the above problems, the present invention provides a composite collector for sulfide ore ...
