Problems solved by technology

At present, cresol black drug, butyl ammonium black drug, ethyl xanthate, butyl xanthate, ethyl disulfide or a combination of two or three of them are commonly used as collectors for galena in China. The collection and selectivity of galenite and sphalerite are often not taken into account, so that there are large consumption of sphalerite inhibitors, poor separation effect, low comprehensive utilization of resources, and environmental pollution during the flotation separation process of galena and sphalerite. Serious pollution and other problems make it difficult to realize economical, efficient and clean utilization of mineral resources

Embodiment Construction

[0022] In the following examples, only the weight parts of the raw materials are changed, and the method for preparing the collector is the same. In order to more intuitively describe the impact of changes in the weight of raw materials in different embodiments on the beneficiation index, lead-zinc sulfide ore was selected to conduct a closed-circuit test of lead-zinc separation flotation under the same conditions. The closed-circuit test process and process parameters are as follows and see figure 1 shown ( figure 1 The test process and process parameters shown are the results of a large number of test optimizations), the products obtained in the mineral processing test are lead concentrate and zinc concentrate, and the grades and recovery rates of lead concentrate and zinc concentrate are listed in Table 1 , through the change of lead and zinc beneficiation indicators to reflect the performance of collectors synthesized by different raw materials by weight. The lead grade o...

Abstract

The invention provides a galena collecting agent. The galena collecting agent is prepared from the following raw materials in parts by weight: 30 to 50 parts of sodium xanthate salt, 20 to 40 parts of diphenyl amino phosphorodithioic acid, 5 to 15 parts of sodium dibutyl dithiocarbamate, and 10 to 30 parts of sodium carbonate. The collecting agent has the advantages of being high in selectivity, high in collecting capacity, high in mineral floating speed, and low in dosage; the collecting agent applied to lead zinc ore separation is able to raise the concentrate grade and recovery of lead, decrease the loss of lead in lead concentrate, and raise the comprehensive utilization rate of a lead zinc ore resource; the collecting agent is applicable to flotation of lead-zinc sulfide ores, including lean ores and refractory ores.

Description

technical field [0001] The invention belongs to the technical field of beneficiation of nonferrous metal ores, and relates to a galena collector and a preparation method thereof. Background technique [0002] Lead metal is mainly used in the manufacture of lead storage batteries, lead alloys, solder, radioactive radiation and X-ray protective equipment. my country has abundant reserves of lead resources, ranking second in the world. Galena is currently the main source of lead metal extraction. Generally, it is necessary to enrich galena by flotation to obtain lead concentrate. Lead concentrate can only be obtained by smelting lead metal. However, galena is usually associated with sphalerite. To enrich the galena by the selection method, the flotation separation of galena and sphalerite must be carried out first, and to realize the effective separation of galena and sphalerite, the selectivity and collection performance of the galena collector must be the most important....
