Abstract

The invention relates to the improved technology for metallurgy beneficiation, in particular to a beneficiation process for copper sulphide ore. After raw ore is ground through a ball mill, pulp is obtained. 1,200 g-1,500 g of lime, 100 g-150 g of lotus leaf and taro leaf juice, 100 g-120 g of lotus leaf and taro leaf residues and 50 g-70 g of pine oil are added in each ton of raw ore, the pH of the pulp is adjusted to be equal to 8, and copper concentrates with the copper content higher than 20% and tailings with the copper content lower than 0.039% are obtained after the pulp is subjected to rough selecting, two-stage fine selecting and four-stage scavenging. The beneficiation production cost is low, a collecting agent is free of toxicity and harm, environment friendliness is achieved, no corrosiveness exists for equipment, the recycling rate is high, and the beneficiation process is mainly used for beneficiation of sulphide ore and oxidized ore.

Description

technical field [0001] The invention relates to a metallurgical beneficiation technology, in particular to a copper sulfide ore beneficiation process. Background technique [0002] The flotation collector is an important drug for recovering minerals. The hydrophobicity of the mineral surface is changed by the collector, so that the floating particles adhere to the flotation collector on the air bubbles, thereby separating the gangue and the slime, and improving Mineral concentrate grade purposes. Current collectors can be divided into anionic, cationic, amphoteric and nonionic according to their ion types. [0003] The commonly used collectors for flotation sulfide ore in my country include xanthate, xanthate derivatives, black medicine, white medicine, benzothiazole mercaptan, benzimidazole mercaptan and benzoxazole mercaptan. A liquid or solid collector is dripped or directly dissolved in the pulp in proportion, and the pulp and the collector are mixed in the mixing tank ...
