Vermiculite - Palabora Mining Company Ltd

Vermiculite is mined from a separate pit, located adjacent to the copper pit. The mining operation involves blasting the ore in the pit, which is approximately 50 metres deep, loading the ore onto trucks, and transporting it to the surface, where it is then sent to the nearby Vermiculite Plant. The pit is a lot shallower than the open copper pit.

What is Vermiculite? - The Vermiculite Association

Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes. Every care is taken in mining operations to minimize the impact on the environment and to restore land to its natural condition when mining ends.

Vermiculite - Wikipedia

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Large commercial vermiculite mines currently exist in the United States of America ...

Vermiculite is a clay mineral group with the general chemical composition (Mg,Fe,Al) 3 (Al,Si) 4 O 10) (OH) 2 4(H 2 O). Often occurring as an alteration product of biotite mica or chlorite in the near-surface zone of weathering, vermiculite is typically found associated with ultramafic rock types such as peridotite and pyroxenite that have been previously altered by intrusions of granite ...

Palabora Mining Company Ltd

The exfoliation process is carried out commercially by passing crude vermiculite through a furnace chamber in a controlled manner. The crude vermiculite then expands at right angles to the cleavage planes, producing concertina-shaped particles many times their original volume. Exfoliated vermiculite can be obtained from commercial exfoliators.
