Embodiment 1

[0024] A rapid separation agent for flotation of large-scale crystalline graphite ore, comprising the following components: 50% by weight of methyl isobutyl carbinol, 30% by weight of petroleum ether and 20% by weight of acetone.

[0025] A kind of flotation process of large scale crystalline graphite ore, comprises the steps:

[0026] The raw ore is a large scale crystalline graphite ore, the fixed carbon content is 15.28%, and the graphite scale diameter is greater than 0.5mm. The kerosene used in this embodiment is through 60wt% sodium lauryl sulfate, 40wt% sulfated monoglyceride It is emulsified by the emulsifier composed.

[0027] A. Crush the above raw ore to -4mm, and then use a ball mill for grinding, the grinding concentration is 60%, the grinding time is 6min, the grinding fineness is -0.15mm and the content is 55%; the grinding product is added with the above-mentioned graphite After the quick-selection agent, put into a flotation machine and carry out quick-select...

Embodiment 2

[0036] A rapid separation agent for flotation of large scale crystalline graphite ore, comprising the following components: 65% by weight of methyl isobutyl carbinol, 20% by weight of petroleum ether and 15% by weight of acetone.

[0037] The difference between this embodiment and embodiment 1 is: 1) the flotation fast separation agent used is different; emulsified by emulsifiers.

Abstract

The invention relates to a large-scale crystalline graphite ore flotation fast selecting agent and a flotation technology. The agent comprises following components including, by weight, 50% to 65% of methyl isobutyl carbinol, 20% to 30% of petroleum ether and 10% to 25% of acetone. The graphite ore flotation fast selecting agent can rapidly select high-quality large-scale graphite ore from neutral pulp, and high-grade large-scale crystalline graphite concentrate can be obtained through the short selection technology free of regrinding; compared with a traditional large-scale crystalline graphite ore flotation technology, graphite scales can be effectively protected, meanwhile, the consumption amount of the floatation agent can be reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a flotation quick-separation agent and a flotation process for large scale crystalline graphite ore, and belongs to the technical field of graphite flotation. Background technique [0002] my country is rich in graphite resources, and its reserves and output rank first in the world. Graphite ore can be divided into crystalline graphite and aphanitic graphite according to the crystal form, and crystalline graphite is divided into dense crystalline graphite and flake graphite. Dense crystalline graphite ore has a small content in nature, and is rarely developed and utilized. Moreover, its grade is high, and it can generally be used directly after manual selection. The flake graphite is the crystalline graphite with more beneficiation research. Flake graphite usually has better crystallization and natural buoyancy, so traditional flotation process can get higher grade and recovery rate. However, since the size of flake graphite...
