the present invention relates to a mineral processing technology and method for refractory chalcopyrite ores, particularly to a mineral processing technology and method for the separation of chalcopyrite from multiple natural types of copper ores containing chalcopyrite, pyrrhotite, talc and serpentine, which belongs to the technical field of mineral processing.

Xinhai was invited to two mining technology exchange

Sep 21, 2020 according to the problems of cyanide tailings, such as environment pollution, resources waste, and hidden danger, xinhai uses tailings reprocessing, tailings dry stacking, mine fulfillment and other methods to realize the comprehensive utilization of cyanide tailings. there aren’t two the same mines in the world.

may 01, 2021 in this paper, a novel process scheme is proposed for the comprehensive utilization and safe disposal of arsenic-alkali slag by the combination of beneficiation and metallurgy. the new technology is novel since every procedure of high arsenic content is run at room temperature, which guarantees good occupational health.

mar 16, 2016 the cement industry has for some time been seeking alternative raw material for the portland cement clinker production. the aim of this research was to investigate the possibility of utilizing iron ore tailings (iot) to replace clay as alumina-silicate raw material for the production of portland cement clinker. for this purpose, two kinds of clinkers were prepared: one was prepared by

to effectively prevent the accumulation of copper tailings from producing acid mine drainage (amd) and maximize the comprehensive utilization of copper tailings, the process of oxidation roasting was adopted to release sulfur in the form of so 2 to achieve the purpose of sulfur recovery later. based on the amd risk assessment, thermogravimetric (tg) analysis, and differential scanning
