Abstract

The invention relates to a collecting agent for flotation of cryptocrystalline graphite ore. The collecting agent is a combined collecting agent AM, wherein the combined collecting agent AM is composed of the following components in parts by weight: 60-70 parts of diesel oil, 20-30 parts of ether alcohol and 10-20 parts of C12H25-N(CH3)2CH2COO. The collecting agent has high collecting capacity for cryptocrystalline graphite and excellent selectivity and can obtain high-carbon graphite concentrate from low-grade cryptocrystalline graphite ore through beneficiation, wherein the fixed carbon content of the high-carbon graphite concentrate is 95%.

Description

technical field

[0001] The invention relates to the field of mineral processing, and specifically provides a beneficiation agent that can be used for flotation of aphanitic graphite ore and a use method thereof. Background technique

[0002] Graphite resources are one of the advantageous mineral resources in my country. According to the crystallization degree of graphite, it can be divided into crystalline (flaky) graphite ore and aphanitic (soily) graphite ore. Judging from the proven reserves of graphite resources in my country, flake graphite resources with good selectability account for about 60%, and aphanitic graphite resources with poor selectability account for about 40%. With the development and utilization of graphite resources, crystalline graphite ores with good selectivity are decreasing day by day, and aphanitic graphite resources, which were not valued before, have attracted more and more attention.

[0003] Due to its extremely fine crystal grain size, some ...
