Embodiment 1

[0065] Such as Figure 1-12 Shown, a kind of graphite flotation treatment process comprises the following steps:

[0066] S1, rough selection of mixed items;

[0067] S101, crushing, transporting the raw graphite ore to a roller mill for crushing and then transporting it to a grading device for grading, controlling the -180 μm product in the grading overflow to reach 70-75%, and the fixed carbon content of the scavenging tailings is less than 1%;

[0068] S102, a sorting, the product obtained in step S101 is input into the classification flotation device, and a part of large flake graphite and a part of fine flake graphite are floated;

[0069] S103, secondary separation, input the remaining product of large flake graphite in step S102 into the classification flotation device again, and float a part of large flake graphite and a part of fine flake graphite, and the remaining product is tailings;

[0070] S2, selection of large scales;

[0071] S201, the large flakes are sel...

Abstract

The invention relates to a graphite flotation treatment process which comprises the following steps: S1, mixed-mesh roughing; S101, crushing; S102, primary separation; and S103, secondary separation. S2, large scale selection, S201, primary selection of large scales, S202, primary grinding of large scales, S203, secondary selection of large scales, S204, secondary grinding of large scales and S205, tertiary selection of large scales; s3, fine scale selection, S301, primary fine scale selection, S302, primary fine scale grinding, S303, secondary fine scale selection, S304, secondary fine scale grinding and S305, tertiary fine scale selection. The invention discloses a device for a graphite flotation treatment process. The device comprises a grading flotation device, a flotation machine and a flotation column. The invention aims to solve or at least alleviate the problem that a traditional multi-section grinding and floating lengthy process cannot well protect large scales and improve the selectivity of fine scales, and provides a graphite flotation treatment process and device.

Description

technical field [0001] The invention relates to the technical field of graphite flotation, in particular to a graphite flotation treatment process and device. Background technique [0002] Graphite is an important non-metallic mineral resource. It has high temperature resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, self-lubricating, thermal conductivity, and electrical conductivity. It is widely used in metallurgy, machinery, electronics, chemical industry, and light industry. , military industry, national defense, aerospace and refractory industries are indispensable non-metallic materials for the development of today's high-tech. [0003] Although flake graphite has very good natural buoyancy, it has specific requirements for protecting large flakes. Therefore, in the production process, the requirements for grinding time and particle size control are different from those of other mineral grinding operations. In the flake graphit...
