Embodiment 1

[0032] Selected raw ore containing Li 2 O0.73%, the main minerals are spodumene, spodumene, beryl, muscovite, sericite, quartz, feldspar, fluorite, tourmaline, kaolinite, calcite, etc., lithium minerals embedded in the ore The characteristics are complex, the embedded particle size is uneven, and mainly fine particles, and the monomer dissociation is poor. Spodumene concentrate obtained by traditional spodumene flotation process contains Li 2 O4.53%, recovery rate 62.37%.

[0033] The complex and refractory low-grade spodumene ore is sorted by adopting the new spodumene flotation process of the present invention, and the sorting steps are:

[0034] (1) Grinding the raw ore, the grinding fineness -0.074mm content is 78%;

[0035] (2) The finely ground pulp is subjected to rough separation of slime to obtain slime products and tailings I. The process conditions of the flotation process are: adding 800g / t of sodium carbonate and 600g / t of sodium hydroxide, and the action time ...

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...
