Separation technology capable of solving mineral derichment problem in grinding and classification system

Abstract

The invention discloses a separation technology capable of solving the mineral derichment problem in a grinding and classification system. The technology is characterized in that a mineral feeding box is connected with a mineral feeding pump, the mineral feeding pump is connected with a hydrocyclone, an underflow outlet of the hydrocyclone is connected with a mineral feeding opening of a separation device, the hydrocyclone flows over to enter the next technology, a product outlet of the separation device is connected with a concentrate groove, a tailing discharging part is connected with concentration equipment which is connected with a grinding machine, and the grinding machine is connected with the mineral feeding box; and the technology comprises the steps that pulp is fed into the mineral feeding box, and then is conveyed into the next-stage technology through the overflowing product of the hydrocyclone, the underflow product of the hydrocyclone is fed into the separation device, qualified products of the separation device are concentrates, tailing pulp of the separating device is fed into the concentration equipment, and the underflow pulp of the concentration equipment is fed into the grinding machine to be ground. According to the separation technology, various problems caused by derichment of target minerals in the grinding and classification system are thoroughly solved, and the aims of improving the recycling rate and grade of the target minerals, improving the grinding machine treatment amount and reducing energy consumption of the grinding machine are achieved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a sorting process capable of solving the problem of anti-enrichment of minerals in the grinding and grading system. Background technique [0002] Grinding is an indispensable link in the mineral processing technology, and it is also the process link with the largest energy consumption. According to statistics, the energy consumption of ore grinding accounts for about 40%~60% of the total energy consumption of the concentrator, and as the ore embedded particle size becomes finer , Usually multi-stage grinding is used to achieve the purpose of dissociation of individual minerals, and the cost of grinding will further increase. Classification equipment is the key supporting equipment for grinding operations. Its function is to send the materials with qualified particle size to the next operation link, and at the same time return the materials with un...
