Embodiment 1

[0013] Put the tin and copper symbiotic sulfide ore from a factory in Gejiu, Yunnan, the copper and sulfur minerals that have undergone mixed flotation, and the copper and sulfur mixed coarse concentrate into the copper and sulfur separation mill (secondary mill), and then carry out copper and sulfur separation flotation selection to produce copper and sulfur concentrates respectively.

[0014] Among them, the ore grinding adopts the combined grinding process of copper-sulfur mixed concentrate with small steel forging ratio and long cone cyclone. This process is to transport the copper-sulfur mixed concentrate to the classification equipment by sand pump for classification. It is 0.074mm particle size. The graded products of -0.074mm grain size directly enter the subsequent sorting process, and the grit products of +0.074mm grain size enter the copper and sulfur separation grinding machine for grinding (with 0.074mm as the classification boundary, -0.074mm grain size The prod...

Embodiment 2

[0017] The single copper sulfide ore from a certain factory in Gejiu, Yunnan Province is subjected to mixed flotation of copper and sulfur minerals, and its copper and sulfur mixed coarse concentrate is put into copper and sulfur separation mill (second stage mill), and then copper and sulfur separation flotation are carried out to produce Produce copper and sulfur concentrates,

[0018] Among them, the ore grinding adopts the combined grinding process of copper-sulfur mixed concentrate with small steel forging ratio and long cone cyclone. This process is to transport the copper-sulfur mixed concentrate to the classification equipment by sand pump for classification. It is 0.074mm particle size. The graded products of -0.074mm particle size directly enter the subsequent sorting process, and the grit products of +0.074mm particle size enter the copper and sulfur separation grinding machine for grinding; the grit products obtained after grinding Enter the copper and sulfur mixe...

Abstract

The invention discloses a copper-sulfur bulk concentrate ore grinding process combining the small steel forging ratio and a long conical cyclone. According to the process, copper-sulfur bulk concentrate is conveyed to grading equipment to be graded through a sand pump, the grading particle size is 0.074 mm, products of -0.074 mm particle size enter a later sorting procedure directly, and sand setting products of +0.074 mm particle size enter a copper-sulfur separating ore grinding machine to be subjected to ore grinding; ore grinding products obtained by conducting ore grinding on the sand setting products enter a pump pool of the copper-sulfur bulk concentrate and then are transferred to the grading equipment to be graded through the sand pump. The products of -0.074 mm particle size enters the later sorting procedure directly, and the sand setting products of +0.074 mm particle size enter the copper-sulfur separating ore grinding machine again to be subjected to ore grinding, and in this way, closed circuit ore grinding is completed by conducting the procedures circularly till ore pulp of required fineness is obtained. Small steel forgings serve as an ore grinding medium of the ore grinding machine. According to the copper-sulfur bulk concentrate ore grinding process combining the small steel forging ratio with the long conical cyclone, the ore grinding efficiency and the grading efficiency can be substantially improved, the investment is low, and the energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of ore fine grinding and classification technology. Background technique [0002] As mine resources continue to change to "poor, fine, miscellaneous, and difficult", the embedded crystal grain size of valuable minerals becomes finer, and the combination of impurity minerals becomes denser. If the fineness of the grinding product fails to effectively and fully dissociate the useful minerals, it will inevitably lead to the phenomenon that the grade of the concentrate product is not high and the impurities exceed the standard due to the influence of impurities, or a large amount of valuable metal minerals are entrained in the tailings. Affect the recovery rate of valuable metal minerals. [0003] The skarn sulfide ore in Gejiu, Yunnan Province has high sulfur content, dense copper-sulfur combination, and fine crystal grain size embedded in copper minerals. Only when γ -200 The dissociation of the monomers can...
