Abstract

The invention provides a flocculent precipitation method for microgranular chalcopyrite by using a mixed flocculant, belonging to the technical field of flocculent precipitation. The method comprises the steps: firstly, preparing the mixed flocculant, wherein the mixed flocculant is formed by mixing anionic polyacrylamide, carboxymethyl cellulose and polyaluminium sulfate; after flotation, adding the microgranular chalcopyrite into the mixed flocculant and lime milk; after flocculent precipitation, further dewatering the microgranular chalcopyrite. The dosage of the mixed flocculant is 2-8g / t relative to the weight of ore pulp. The method increases the precipitation speed of chalcopyrite, reduces lime dosage, increases the underflow concentration of a thickener, can solve the problem of solid persisting in chalcopyrite, and increases the economic benefit. The method has the advantages of simple preparation, low operation cost and obvious effect.

Description

Technical field

[0001] The invention relates to the technical field of flocculation and sedimentation, in particular to a method for applying a mixed flocculant to flocculate and sediment fine chalcopyrite. Background technique

[0002] Jiangxi Jiujiang, Shangrao, Anqing, Anqing, Tongling, Anhui, and other places are a very important deposit in the middle and lower reaches of the Yangtze River in my country. This type of deposit is a large-scale comprehensive deposit of copper, sulfur and iron. , Iron resources are the main mining target. There are many other places in the country for such resources. Typical examples are the Wushan Copper Mine, Chengmenshan Copper Mine, and Dexing Copper Mine in Jiangxi; Anqing Copper Mine in Anhui and Jinding Mining in Jing County.

[0003] Due to the small mass and large specific surface area of ​​fine-grained chalcopyrite, the particles have high specific surface energy, and the mineral surface has oily agents, so it is very easy to form a floati...
