Problems solved by technology

With the reduction of high-grade and coarse-grained lithium ore resources, in the face of poor, fine, and miscellaneous lithium resources, it is difficult to obtain qualified flotation lepidolite concentrate by using traditional chemical solutions.
Secondly, the flotation process is complicated, the dosage of chemicals is large, and the independence of each link is not strong.
With the depletion of ore resources, it is difficult to use a single traditional beneficiation process
In order to obtain ideal beneficiation indicators, the flotation process is becoming more and more complicated, and the cost of chemicals is increasing; the complexity of the process leads to a decrease in flexibility, and a small link may lead to the paralysis of the entire operation

Embodiment Construction

[0014] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0015] Such as figure 1 , figure 2 As shown, the present invention adopts the flotation process to recover lepidolite from the tantalum-niobium ore gravity separation tailings. First, the tantalum-niobium ore recovers the tantalum-niobium through gravity separation. In the selection process, under normal temperature and pressure, coconut oil amine is used as foaming agent, ether alcohol, turpentine and other compound agents are used as collector, and the concentration of 2% to 50% (mass ratio...

Abstract

The invention discloses a process method for flotation lepidolite, specifically: the tailings of tantalum-niobium ore after re-election are deslimed and then enter the flotation process, or directly enter the flotation process, add flotation agents, and perform flotation Obtain high-quality lepidolite concentrate. The invention recovers lepidolite by flotation in neutral pulp, and has the advantages of simple process, low chemical consumption, high efficiency, safety and environmental protection of flotation chemical, and the like.

Description

technical field [0001] The invention relates to a process method of flotation lepidolite. Background technique [0002] Lepidolite is one of the main industrial minerals for extracting lithium. Lithium is an important energy metal. Its application in high-energy lithium batteries and controlled thermonuclear reactions makes it an important raw material to solve long-term energy supply for human beings. Lithium series products are widely used in smelting, refrigeration, atomic energy, aerospace and ceramics, glass, grease, rubber, welding, medicine, batteries and other industries. my country's lithium resources are relatively rich, but the grade is relatively low, the embedded particle size is fine, and the utilization level is low. The resource advantage has not yet been transformed into an economic advantage. In this case, my country should develop the development technology of lithium resources as soon as possible. [0003] Different lithium ores have different properti...
