The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with a lining of carbon and graphite rods is used.

Lithium minerals are usually associated with gangue minerals, such as quartz and feldspar, so the content of lithium oxide in the ore is low. These useful components are enriched through beneficiation to obtain lithium concentrate, which usually includes gravity separation, magnetic separation, flotation, and other processes (Tadesse B et al., …

Talc extraction involves the crushing, grinding, and processing of the ore, which releases particulate matter into the air. These airborne particles, including respirable crystalline silica, can harm air quality. Prolonged exposure to talc dust may harm respiratory health, causing pneumoconiosis and silicosis among miners and nearby communities.

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.

1 Geology. Talc is hydrated magnesium silicate (Mg 3 Si 4 O 10 (OH) 2 ); however, it may contain mineral impurities such as chlorites and fibrous amphiboles, calcite, magnesite, and dolomite. Talc has a characteristic perfect-basal exfoliation known as lamellarity or platiness due to low- to moderate-grade metamorphism during its formation.
