Ore dressing method of spodumene quarry

Abstract

The invention discloses an ore dressing method of a spodumene quarry, which comprises the following steps: raw ore grinding, slime floating, spodumene fast roughing, spodumene fast selecting, spodumene slow roughing, spodumene slow selecting and other steps, and a spodumene concentrate is finally obtained. The spodumene quarry separated by adopting the ore dressing method has good separation index, and the grade and the recovery rate of the spodumene concentrate are high. The ore dressing method is a new spodumene flotation process with the advantages of economy, applicability, simplicity, cleanness, strong controllability and good separation effect and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a spodumene ore beneficiation method, in particular to a flow structure of spodumene flotation. Background technique [0002] my country is rich in spodumene mineral resources, ranking fourth in the world. However, at present, the utilization efficiency of spodumene resources in my country is not high. The utilization of spodumene resources with uneven and complex properties is not ideal. Often due to the finer particle size of spodumene, various types of gangue minerals, severe mudification, and complex properties, it is difficult to recover spodumene by flotation. It is difficult to obtain spodumene concentrate with high grade and recovery rate. For these complex and low-grade fine-grained spodumene mineral resources, most mines either have not been effectively developed due to the difficulty of sorting, or because of the complex nature of the ore, only part of the spodumene concentrate has been sorted out, but the concentrate...

[0002] my country is rich in spodumene mineral resources, ranking fourth in the world. However, at present, the utilization efficiency of spodumene resources in my country is not high. The utilization of spodumene resources with uneven and complex properties is not ideal. Often due to the finer particle size of spodumene, various types of gangue minerals, severe mudification, and complex properties, it is difficult to recover spodumene by flotation. It is difficult to obtain spodumene concentrate with high grade and recovery rate

For these complex and low-grade fine-grained spodumene mineral resources, most mines either have not been effectively developed due to the difficulty of sorting, or because of the complex nature of the ore, only part of the spodumene concentrate has been sorted out, but the concentrate grade Both the recovery rate and the recovery rate are low, and the impurity content is high

[0003] The traditional spodumene flotation process mostly uses fatty acids as collectors to directly float spodumene minerals. Although this process can float most of the spodumene minerals that are easy to float, but when the coarse concentrate is used for spodumene Due to the complex properties of gangue minerals, spodumene and gangue minerals are closely related, which makes it difficult to separate spodumene and gangue minerals, and it is difficult to obtain high-grade spodumene concentrates

At the same time, it is more difficult for those spodumene minerals with poor buoyancy and finer particle size to be recovered by flotation, which makes the overall utilization level of such spodumene resources not high

[0004] The Chinese invention patent "Spodumene ore dense medium-strong magnetic separation process", patent number CN101147888A discloses a spodumene ore separation method, which proposes the recovery of spodumene by the combined process of dense medium separation and strong magnetic separation, However, for gangue minerals with complex properties, such as ores containing a large amount of mica and lepidolite, it is difficult to separate lithium minerals from mica-like gangue minerals by using strong magnetic separation, resulting in low concentrate grades; Spodumene mineral, difficult to recover by heavy media beneficiation

Therefore, this process only has a certain effect on spodumene ore with high grade, simple embedded distribution characteristics and easy selection, but cannot be applied to complex and difficult-to-separate low-grade spodumene ore, and the scope of application is narrow
