The Process Flow of Spodumene Mainly Steps:

The process flow of spodumene mainly includes the following steps:

1. Grinding and grading

Firstly, spodumene ore will be ground to facilitate subsequent processing. The ground ore will be graded to ensure that the particle size of the ore meets the requirements of flotation.

2. Flotation

In the flotation stage, flotation agents are added to separate spodumene from other minerals. This step mainly utilizes the difference in specific gravity between spodumene and other minerals to select spodumene through a flotation machine.

3. Use of adjustment agents

In the flotation process, in order to expand the difference in floatability between spodumene and gangue minerals, adjusters need to be added. Common adjusters include sodium carbonate, sodium hydroxide, and sodium sulfide.

4. Transformation roasting

Transformation roasting is a method of converting spodumene into soluble substances. During this process, spodumene will be transformed into β Mix with sulfuric acid and calcine.

5. Leaching, purification, and lithium precipitation

The transformed calcined spodumene will undergo leaching to dissolve lithium elements. Then impurities are removed through purification, and finally industrial lithium carbonate is obtained through lithium precipitation.

The above is the main process flow of spodumene. It should be noted that the specific process flow may vary depending on factors such as the mineral properties, lithium grade, and impurity content of spodumene
