Embodiment 1

[0030] The phosphate rock mined in a certain area has a comprehensive grade of phosphorus of 8-20%, a grade of silicon of 30-40%, a grade of calcium of 15-22%, and a grade of magnesium of 4-8%.

[0031] Phosphate ore photoelectric beneficiation and separation process includes the following steps:

[0032] (1) The high-magnesium raw ore is transported to the PEX250*1000 jaw crusher through the belt conveyor, and the crushed ore is transported to the double-layer circular vibrating screen through another belt conveyor. The upper screen of the circular vibrating screen is 50*50mm The screen, the lower screen uses a 20*20mm screen. After screening, the ore > 50mm is transported to the jaw crusher into the hopper through another feeding belt and crushed again. The 20-50mm ore (20- The average grade of 50mm ore is 12-15%, which can be used as photoelectric sorting raw material) through another transfer belt to the stacking point as photoelectric sorting raw material. Transport to t...

Abstract

The invention provides a photoelectric beneficiation sorting process for phosphorite. The process comprises the following steps of screening phosphorite raw ore; conveying the ore obtained through screening into a photoelectric sorting machine through a belt conveyor, conducting X-ray ore radioscopy and substance recognition , recognizing each piece of ore through X-rays, collecting data through adetector, and recognizing and distinguishing the ore and waste rock through an intelligent algorithm; and after recognition by the photoelectric sorting machine is completed, a high-speed gas exhaustgun is used for accurate striking to separate concentrate from tailings , and then photoelectric beneficiation of the phosphorite can be completed. In the process of screening the phosphorite raw ore, the raw ore is crushed and vibrated to obtain ore with the particle size larger than 50 mm, then the ore is crushed again, and obtained ore with the particle size being 20-50 mm is conveyed into thephotoelectric sorting machine to be subjected to photoelectric sorting. At present, the process is only targeted at medium-phosphorus-layer high-magnesium phosphorite, the sorting effect is remarkable, and when the grade of sorted raw ore is 17.5%, the yield can reach 40% or above, and the recovery rate is high.

Description

technical field [0001] The invention relates to a phosphate ore beneficiation process, specifically adopting photoelectric technology to realize the separation of phosphate ore. Background technique [0002] At present, the most commonly used beneficiation methods for phosphate rock are gravity beneficiation and flotation. The process of gravity beneficiation is simple and the processing capacity is large, but the beneficiation recovery rate is low; Chemicals will cause certain pollution, environmental protection issues are difficult to deal with, and the requirement for tailings to be wet-drained and stacked will greatly limit the establishment of flotation plants. [0003] Flotation, also known as flotation beneficiation, is the most widely used and most effective mineral processing method for the separation of fine particles and fine particle materials. According to the different properties of the ore surface, according to the different effects of the ore on water, air bu...
