Novel gold flotation catching agent

Abstract

The invention discloses a novel gold flotation catching agent. The catching agent is composed of sodium n-butylxanthate, sodium isoamylxanthate and butylamine aerofloat. The weight ratio of the sodium n-butylxanthate to the sodium isoamylxanthate to the butylamine aerofloat is 4 to 8:1 to 5:0.5 to 2. Preferably, the weight ratio of the sodium n-butylxanthate to the sodium isoamylxanthate to the butylamine aerofloat is 6:3:1. The mode that in the traditional gold floatation process, the sodium n-butylxanthate with the single carbon chain is adopted is broken through, different catching properties and selectivity of different carbon chains are adopted, the catching properties of the sodium n-butylxanthate and the selectivity of the sodium isoamylxanthate are complemented, the selectivity of the butylamine aerofloat is added, the three agents are fully mixed, contradiction of the catching capability and the selectivity is resolved, and therefore the catching properties and the selectivity are developed to the great extent. Compared with a traditional agent, the recycling rate of the novel gold flotation catching agent is improved by 0.5 percent, the use number of the agents is reduced by 12 g / t, and the concentrate grade is improved by 0.74 g / t.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a novel gold flotation collector. Background technique [0002] Collector, English name: catching agent, is a flotation agent that changes the hydrophobicity of the mineral surface and makes the floating mineral particles adhere to the air bubbles. [0003] There are many types of collectors, which can be divided into anionic, cationic, amphoteric and nonionic according to their ionic properties; they can be divided into sulfide ore collectors, oxide ore collectors, nonpolar mineral collectors according to their application range Collectors and collectors for deposited metals. [0004] Commonly used sulfide ore collectors include xanthate, xanthate derivatives, black medicine, white medicine, benzothiazole mercaptan, benzimidazole mercaptan, benzoxazole mercaptan, etc. [0005] Oxide collectors mainly include fatty acids and their sodium soaps, alkyl sulfonates, alky...

Problems solved by technology

Within a certain range of collector concentration, as the concentration of the agent increases, the adsorption capacity increases, and the flotation recovery rate increases significantly; when the concentration reaches a certain value, the recovery rate decreases with the increase in concentration and adsorption capacity; When the concentration is too high, the adsorption capacity can continue to increase, but the flotation recovery rate no longer increases, or even decreases.
