A kind of screening method of silicon-calcium colloidal phosphate rock

Abstract

The invention provides a screening method of silicon-calcium collophanite ore. The screening method comprises the steps that water washing is carried out on the raw ore; a screening well is arranged on a screening site; a first-stage screening device, a second-stage screening device and a third-stage screening device are installed in the screening well from top to bottom; and the raw ore passes through the first-stage screening device, the second-stage screening device and the third-stage screening device from top to bottom to obtain ore products in different specifications. By adopting the technical scheme, the screening well and the corresponding multi-stage screening devices are simple in structure, the screening process is simplified, the investment cost of hardware facilities in the screening process is reduced, and the screening accuracy is improved due to the fact that the raw ore is washed with water before screening. In addition, by means of the screening method, the differentore products obtained after screening are applied to different purposes, the best effect is achieved, and the utilization rate of the silicon-calcium collophanite ore is improved.

Description

technical field [0001] The invention relates to the technical field of mineral processing industry, in particular to a screening method for silicon-calcareous colloidal phosphate rock. Background technique [0002] The beneficiation process of siliceous-calcareous collophosphine has always been a major problem in the mineral processing industry. If siliceous-calcareous collophosphine is directly used in chemical production without the corresponding beneficiation process, the The main component is silicate, which is easy to chemically react with other chemical production raw materials to form gelatinous substances, and is easy to adhere to the corresponding pipes in chemical equipment, affecting the normal operation of chemical production equipment. At present, the beneficiation process of siliceous-calcareous colloidal phosphate generally adopts the forward-reverse flotation process, but the investment cost of this kind of beneficiation process equipment is high, and the flo...

[0002] The beneficiation process of siliceous-calcic collophosphine has always been a major problem in the mineral processing industry. If siliceous-calcareous collophosphine is directly used in chemical production without the corresponding beneficiation process, the The main component is silicate, which is easy to chemically react with other chemical production raw materials to form gelatinous substances, and is easy to adhere to the corresponding pipes in chemical equipment, affecting the normal operation of chemical production equipment

At present, the beneficiation process of siliceous-calcareous colloidal phosphate generally adopts the forward-reverse flotation process, but the investment cost of this kind of beneficiation process equipment is high, and the flotation foam is easy to stick. Therefore, for the corresponding mining enterprises, it is urgent to develop a low-cost mineral processing process and rationally utilize various products after mineral processing to improve the utilization rate of siliceous-calcareous collophosite
