Abstract

The invention relates to an ore concentration technique for tin sulphide ore rough concentrate. The technique comprises the following steps of grinding of tin rough concentrate, sulfide flotation, cassiterite flotation, cassiterite foam flotation and tailing re-flotation. The ore concentration technique combines full ore grinding, sulfur flotation, tin flotation, table concentration and scavenging and is an ore separation method capable of sufficiently and effectively recovering valuable resources, such as valuable metal tin and sulphur (copper) elements, in tin rough concentrate and achieving separation and enrichment of the valuable resources under the condition that the mineral substance composition is not changed. By adoption of technique combining full ore grinding, sulfide flotation, sulfide detinning flotation, cassiterite flotation, cassiterite foam flotation, and table concentration and scavenging of tailings, concentration of the tin sulphide ore rough concentrate is perfected, and the recycling rate of tin metal is increased.

Description

Technical field

[0001] The invention relates to the technical field of a method for beneficiating tin sulfide ore coarse concentrate. Background technique

[0002] In the traditional non-ferrous metal beneficiation process, the tin-bearing sulfide ore is disturbed and affected by the high specific gravity sulfide minerals, not only the tin recovery rate is low, but also the grade of the crude tin concentrate produced is generally 6-13%, and contains a large amount of Sulfide cannot meet the raw material requirements of the smelter. It must be processed by the tin coarse concentrate selection process to produce qualified tin concentrate with a tin content of more than 40% and the impurity content can reach the standard. Sales. Therefore, the pros and cons of the tin coarse concentrate selection process directly affect the economic benefits of the concentrator.

[0003] At present, the selection process of the coarse concentrate of tin sulfide ore is divided into: manual discontinu...
