Abstract

The invention relates to a spodumene ore processing method and belongs to the field of ore production. The spodumene ore processing method aims at solving the technical problem of providing an ore processing method for spodumene ore. The spodumene ore processing method is formed by steps of ore grinding, roughing for two times, scavenging and selecting for two times and finally the spodumene concentrate is obtained. The spodumene ore processing method has the advantages of being simple in technological process, good in used medicament selectivity, strong in collecting capability and low in medicament amount, greatly reducing processing costs and enabling obtained spodumene concentrate level to be more than 6 % and the recovery rate to be more than 85 %.

Description

technical field [0001] The invention relates to a beneficiation method of spodumene ore, which belongs to the field of ore production. Background technique [0002] At present, the basic source of lithium products, a new material for lithium batteries that is highly praised by the world, is mainly lithium extracted from ore and lithium extracted from brine. Lithium extraction from brine is much more affected by the natural environment and conditions than lithium extraction from ore. Lithium extraction from brine also requires intermediate products (such as lithium chloride and lithium carbonate). Battery-grade lithium products for lithium batteries need to be purified from industrial-grade products. Due to the high ratio of magnesium to lithium or harsh natural conditions, lithium extraction from brine in China has not been able to reach production capacity, and lithium extraction from ore is the main method. The ore lithium extraction technology is mature, the versatility ...
