Embodiment Construction

[0023] The following are only preferred implementations of the present invention, and the scope of protection of the present invention is not limited to this example, and various technological solutions that have no substantial difference from the concept of the present invention are within the scope of protection of the present invention.

[0024] A copper-cobalt-nickel polymetallic mine in a certain place in Australia is produced from a sedimentary carbonaceous shale deposit, and the valuable minerals in the ore are copper, cobalt, and nickel. The raw ore contains 2.80% copper, and copper exists in five forms: primary copper sulfide, secondary copper sulfide, combined copper oxide, copper carbonate and free copper ions, of which free ion copper accounts for 12.09% of the total copper; cobalt and nickel in the raw ore The grades are 0.16% and 0.16% respectively, and they exist in three forms of independent minerals, mechanical mixing and peaty adsorption. Most cobalt minerals...

Abstract

The invention belongs to a method for beneficiating copper/cobalt/nickel mine and specifically relates to a method for beneficiating ion-state copper/cobalt/nickel mine of ore; copper ore containing a plenty of ion-state copper/cobalt/nickel in raw ore is beneficiated except copper/cobalt/nickel sulphide; copper/cobalt/nickel sulphide mine can be recycled in a conventional beneficiating and floating method; and the ion-state copper/cobalt/nickel cannot be recycled and is lost in gangue along with the emission of floated gangue. According to the invention, regulating agent and precipitator are added to gangue pulp in a stirring manner after floating the copper/cobalt/nickel sulphide mine; the ion-state copper/cobalt-nickel in mine pulp is reacted with the precipitator so as to generate copper/cobalt/nickel of a compound; the copper/cobalt/nickel is recycled so as to acquire a copper/cobalt/nickel concentrate product in a floating method; compared with conventional flotation, cobalt concentrate recycling rate is increased by 34.01%; and nickel concentrate recycling rate is increased by 31.58%.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a beneficiation method of non-ferrous metal ore containing ionic copper-cobalt-nickel ore. Background technique [0002] The ore is a copper-cobalt-nickel ore containing a large amount of ionic copper, cobalt, and nickel. The minerals are intercalated with fine particle size and close symbiotic relationship. Copper in the form of ions and copper oxide accounts for 19%, and cobalt and nickel are mainly in the form of ions. A small amount of copper exists in the form of ions and is adsorbed by peat, so the ore is extremely difficult to separate. It has been 50 years since the ore was discovered. Over the past 50 years, due to the complex nature of the ore, many research institutions at home and abroad have conducted a lot of research work on the recovery technology of the ore, but no effective beneficiation method has been obtained. [0003] my country also has a lot of this type of ore, ...
