Usage

Description

Lepidolite, a variety of mica, is a fluorosilicate of potassium, lithium, and aluminum found in pegmatites. It was historically used as a lithium source before spodumene became the primary ore for lithium recovery in the chemical industry. Lepidolite is also characterized by the presence of rubidium as an impurity.

Uses

Used in Chemical Industry:
Lepidolite is used as a lithium source for the chemical industry. It was previously utilized for the recovery of lithium through a process involving sulfuric acid, similar to the method used for spodumene by the Lithium Corporation of America. A more recent method involves heating a mixture of lepidolite and potassium sulfate just below the melting point, followed by extraction with water to obtain a solution of lithium sulfate.
Used in Agricultural Applications:
Lepidolite, being a fluorosilicate of potassium, lithium, and aluminum, is used in the agricultural industry for various purposes. Its composition provides essential nutrients and minerals to the soil, promoting plant growth and overall agricultural productivity.
