Abstract

The invention relates to a flotation method of spodumene ore. According to the method, in a spodumene ore flotation process, a regulating agent C2-C6 organic polybasic acid solution or a salt solutionthereof is added into ore pulp and performs pulp regulating, wherein the C2-C6 organic polybasic acid is one or a plurality of materials selected from citric acid, tartaric acid, oxalic acid, succinic acid and malic acid, and the use amount of the C2-C6 organic polybasic acid is 0.05-0.5 kg / t. raw ore. According to the invention, the new regulating agent is added on the basis of the common spodumene flotation method, so that the spodumene flotation separation performance is improved, fine-grain spodumene flotation does not need desliming, the recovery rate is high, the flotation process is simplified, and the utilization rate of lithium resources is increased.

Description

technical field [0001] The invention belongs to the technical field of lithium ore beneficiation, in particular to a spodumene ore flotation method. Background technique [0002] In the beneficiation of spodumene, flotation is the most important treatment method used in current industrial production. The common method of spodumene flotation is "three alkalis and two soaps". "Three alkalis" refers to the adjustment of flotation. Agents are sodium carbonate, sodium hydroxide, calcium chloride, "two soaps" means that the collectors for flotation are oleic acid (soap) and oxidized paraffin wax soap. For fine-grained spodumene, it needs to be ground to a finer particle size before the monomer can be dissociated. A large amount of fine mud is produced during the grinding process, which reduces the sorting performance of spodumene flotation. The commonly used " During flotation with the method of "three alkalis and two soaps", it is necessary to remove the fine mud or go through m...
