Problems solved by technology

[0002] At present, the sorting process for low-grade quartz vein gold mines is a two-stage closed-circuit crushing process, a two-stage closed-circuit grinding process, and flotation is a roughing process, a second sweeping process, a three-time beneficiation and flotation beneficiation and return in sequence. The process flow is the traditional conventional process used in gold beneficiation. The crushing ratio of the existing process is small, and it is difficult to achieve the goal of "more crushing and less grinding". It is especially not suitable for quartz-type gold mines with high hardness, and the grinding cost is too high. , can not meet the requirement of monomer dissociation

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0025] The beneficiation process flow of prior art quartz vein type gold mine is as follows figure 1 As shown, the raw ore enters the raw ore bin through the 600*600mm grid screen, and the grid screen is equipped with a fixed breaker. The large pieces larger than 600mm are broken by the fixed breaker, and the material on the screen is fed into the jaw crusher through the bar feeder. First-stage crushing, the crushing particle size is less than 80mm, the first-stage crushing product and the second-stage crushing product are combined and sent to the double-layer circular vibrating screen with a screen hole of 10mm for screening through the belt conveyor, and the upper product is sent to the cone through the electric vibrating feeder. The crusher performs secondary crushing. After being weighed by the electronic belt conveyor, the screened produ...

Abstract

The invention discloses a beneficiation method for quartz vein type gold deposit. The beneficiation method for the quartz vein type gold deposit includes the steps of using a jaw crusher to crush raw ore, sending crushed mineral material into a double layer circular vibrating screen to be sieved, putting sieved and qualified mineral material into a grid type ball mill for single stage grinding, returning unqualified mineral material after two stage crushing back to the double layer circular vibrating screen, separating magnetic and non-magnetic minerals after discharging material from single stage grinding passing a magnetic arc, making magnetic minerals for magnetic separation to obtain iron ore concentrate and putting the non-magnetic minerals separated through the magnetic arc into a sorting system after twice classification. Compared with the prior art, with beneficiation method for quartz vein type gold deposit, the content of fine particles of a crushed final product is mostly of 80.3%, crushing efficiency is improved, wear rate of a steel ball is decreased by 9%, ferrous metals can be recycled, synchronous improvement of ore dressing recovery percentage and concentrate grade is realized with the recovery percentage increased by 4.2% and the concentrate grade increased by 3.5 grams per ton, power consumption rate is reduced by 13.86%, and cost is reduced by 15.0%.

Description

technical field [0001] The invention belongs to the field of gold beneficiation, and in particular relates to a beneficiation method and device for quartz vein type gold ore. Background technique [0002] At present, the sorting process for low-grade quartz vein gold mines is a two-stage closed-circuit crushing process, a two-stage closed-circuit grinding process, and flotation is a roughing process, a second sweeping process, a three-time beneficiation and flotation beneficiation and return in sequence. The process flow is the traditional conventional process used in gold beneficiation. The crushing ratio of the existing process is small, and it is difficult to achieve the goal of "more crushing and less grinding". It is especially not suitable for quartz-type gold mines with high hardness, and the grinding cost is too high. , which cannot meet the requirement of monomer dissociation. Contents of the invention [0003] The purpose of the present invention is to improve t...
