INTRODUCTION OF LITHIUM SPODUMENE

Lithium spodumene is the primary mineral source for the lithium industry and is a characteristic mineral found in lithium-rich granitic pegmatites. It mainly forms in granitic pegmatite veins. Unlike other pyroxene group minerals, lithium spodumene is a pegmatitic mineral and is often associated with quartz, tourmaline, beryl, and other minerals.

As a provider of comprehensive grinding equipment solutions, Zenith has been committed to developing more efficient, energy-saving, and environmentally friendly grinding equipment of lithium spodumene，such as LM vertical mill，MTW European trapezium mill，XZM ultrafine mill，LUM ultrafine vertical mill and etc.

INTEGRATED SOLUTION FOR DEEP PROCESSING OF LITHIUM SPODUMENE

In the context of the current transformation and upgrading of the energy industry, the lithium battery new energy industry is rapidly emerging. Among these, lithium carbonate, as an important raw material for lithium battery electrode materials, is experiencing a continuous increase in demand. Against this backdrop, the research on the process of extracting lithium carbonate from spodumene has become particularly important.

Overview of the Grinding Process for Producing Lithium Carbonate from Spodumene:

The process of producing lithium carbonate from spodumene primarily includes steps such as crushing and grinding of spodumene or lepidolite, leaching, crystallization, and drying. Among these, crushing and grinding is the first step in the process of producing lithium carbonate from spodumene and is a critical link that determines the quality of the lithium carbonate product.
