Embodiment 1

[0016] Grind chalcopyrite and talc until the particle size is less than 74um, take 1g of chalcopyrite and 1g of talc into the flotation cell of the hanging cell flotation machine, add 40mL of water and stir to obtain a uniform slurry, adjust the resulting slurry with a pH regulator The pH is 5, add 100mg / L concentration of 1% inhibitor tragacanth gum and stir for 5min, 20mg / L concentration of 5% collector butyl xanthate and stir for 3min, 10mg / L foaming agent No. 2 oil and stir for 1min , and then inflated flotation to obtain the flotation foam and the product in the tank, and the product is dried, weighed and tested. The results of the beneficiation test are shown in the table below.

Abstract

The invention provides a method for separating chalcopyrite from talc with tragacanth and belongs to the field of separating copper sulfide minerals from hydrophobic silicate gangue. The method comprises the steps that the chalcopyrite and the talc are levigated and put into a flotation tank of a hanging trough flotator, an appropriate amount of water is added into the flotation tank, and stirring and slurry mixing are conducted; pH of slurry is adjusted with a pH adjustment agent; the tragacanth which is an inhibitor, butyl xanthate which is a collecting agent and 2 # oil which is a foaming agent are added into the flotation tank, and stirring is conducted for 1-5min; air flotation is conduced, and concentrate and a tailings product are obtained; and the products are dried, weighed and tested. The tragacanth, the efficient inhibitor, can be adsorbed on the surface of the hydrophobic silicate gangue, so that a selective inhibiting effect is achieved on the hydrophobic silicate gangue; and meanwhile, the tragacanth is non-toxic, easy to degrade and low in cost.

Description

technical field [0001] The invention relates to the technical field of separation of copper sulfide minerals and hydrophobic silicate gangue, in particular to a method for separating chalcopyrite and talc by using tragacanth gum. Background technique [0002] Copper resources are one of the most widely used important basic raw materials in the development of the national economy. They are widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in my country. my country is a country with large copper resources, but in recent years, the growth rate of copper consumption has been significantly faster than the growth rate of production. With the acceleration of infrastructure construction such as communications and electric power and the popularization of automobiles and information technology products, China's demand for ...
