The significance of optical sorting in the fluorite sorting process.

Fluorspar ore in nature due to its different formation conditions, can be broadly sorted into a single type of fluorspar ore, calcite - fluorspar type ore, quartz - fluorspar type ore, sulfide fluorspar type ore, siliceous rock type fluorspar ore, carbonate type fluorspar ore and barite - fluorspar type ore seven.

In the fluorite ore beneficiation conventional methods are mainly hand-selected, re-election, flotation 3 kinds of methods. Hand sorting is used for fluorite crystallisation of large blocks of fluorite; re-election is used for pre-selection operations of lump ores or flotation for metallurgy; flotation is used for the production of high grade concentrates for the chemical and ceramic industries.

Today brings a new fluorspar sorting method - photoelectric sorting.

What are the technical advantages of photoelectric sorting in the fluorspar sorting process? What impact does it have on the existing fluorspar sorting process? What fluorspar sorting process can be replaced? Firstly, photoelectric sorting can sort fluorspar ores above 0.5cm and accurately sort out high-grade fluorspar concentrates and tailings according to the difference in surface physical characteristics between fluorspar concentrate and waste rock. Enhance the economic value of fluorspar ore and improve mine efficiency.

The following are the implications of photoelectric sorting in various types of fluorspar ore sorting:

Firstly the ability to replace the existing manual hand sorting process and to increase the throughput level of fluorspar ores;

For fluorspar ores in which the economic value of lump ore concentrates is greater than that of flotation fluorspar concentrates, the photoelectric sorting equipment is used to sort out such fluorspar concentrates and throw out the tailings before entering flotation to improve the overall economic value of the fluorspar ore;

High grade fluorspar                              Into flotation fluorspar

For fluorspar ores with low average grade, pre-throwing waste rock from them through sorting to improve the grade of the fluorspar ore entering flotation, reduce the flotation ore handling capacity and save flotation costs;

Some of the fluorspar ore has a high calcium carbonate content, and after entering the flotation process, the flotation chemicals are inhibited from trapping the fluorspar concentrate due to the similarity between calcium carbonate and fluorspar flotation properties, resulting in increased flotation costs, but the collection of fluorspar concentrate after flotation is lower than conventional levels. This type of fluorspar ore is sorted by photoelectricity and pre-thrown waste high calcium carbonate content ore to reduce the calcium carbonate content of fluorspar ore and save production costs.

In the case of fluorspar ore with a calcium carbonate content of 10% or more, the calcium carbonate content in the fluorspar ore is reduced to around 1.0% by sorting. The equipment used is photoelectric sorting equipment - artificial intelligence sorting machine using the characteristic differences between calcium carbonate and fluorite ore, to establish a sorting model, in the sorting process by throwing high calcium carbonate fluorite ore, to ensure the purpose of reducing calcium carbonate in the fluorite concentrate after sorting.
