Spodumene is a lithium-containing mineral with the chemical name lithium aluminum silicate. It is an important lithium mineral and one of the main raw materials currently used in the lithium industry. Spodumene usually appears in gray, green or light pink, and sometimes it can also take on a transparent to semi-transparent crystal form. Its chemical formula is LiAl(SiO3)2, which contains lithium, aluminum, silicon and oxygen elements.
Spodumene Process flow
Phase One: Crushing
The raw spodumene ore is preliminarily crushed through crushing equipment (such as crushers, hammer crushers, etc.) to break the ore blocks into smaller particles.
Phase Two: Grinding
The crushed spodumene particles are sent into the grinding equipment for fine grinding treatment. Commonly used grinding equipment includes vertical grinding mills, ball mills, etc. Through grinding operations, the spodumene particles are further refined into the required powder form.
Phase Three: Grading
The ground spodumene powder is usually classified to obtain a particle size distribution that meets the requirements. Classification can be carried out through equipment such as vibrating screens and cyclones, where powders are categorized according to different sizes to obtain the required particle size grades.
Phase Four: Magnetic separation
Spodumene ore may contain some magnetic minerals or impurities. To improve the purity of spodumene, magnetic separation operations can be carried out. Magnetic separation equipment (such as magnetic separators, magnetic separation rollers, etc.) can remove magnetic impurities and improve the quality of spodumene.
Phase Five: Drying
After grinding, spodumene powder usually needs to undergo drying treatment to remove moisture content, improve stability and storability. Commonly used drying equipment includes rotary dryers, air flow dryers, etc.
Phase Five: Packaging and Storage
The spodumene powder processed by the grinding process will be packaged and properly stored for subsequent transportation and use.
Note: The specific process flow may vary due to differences in the nature of the ore, product requirements, and production equipment. In practical applications, it is necessary to carry out process design and adjustment based on specific circumstances.
Main uses
