Abstract

The invention discloses a novel high-efficiency, energy-saving and environment-friendly flotation reagent belonging to the technical field of coal washing. It consists of the following parts by weight: 30-70 parts of diesel oil, 10-50 parts of sec-octanol, 25-45 parts of heptanol and 15-35 parts of 2-ethylhexanol. The selection aid of the present invention is non-toxic and has no irritating smell, energy saving and high efficiency, high safety, high foaming and collecting performance, and the dosage is 0.1-0.5kg / ton of coal slime, which saves the cost of coal preparation and improves the precision. coal yield.

Description

technical field [0001] The invention belongs to the technical field of coal washing, and in particular relates to a high-efficiency, energy-saving and environment-friendly flotation agent. Background technique [0002] In the process of flotation beneficiation, in order to effectively separate useful minerals and gangue minerals, or to separate various useful minerals, it is often necessary to add certain agents to change the physical and chemical properties of the mineral surface and the properties of the medium. These agents are collectively referred to as Flotation agent. Flotation reagents can be traditionally divided into collectors, frothers, depressants, pH regulators, etc. [0003] At present, with the continuous development of the coal washing industry and washing equipment, the original common flotation reagents generally use poor oil products as raw materials, which have disadvantages such as large dosage, poor effect, and no guarantee for the health of employees...
