DH QUARTZ – Pure Quartz for Industrial Processing
Quartz (SiO2) in various forms are among the most common minerals in the earth’s crust, second only to Feldspar. Also known as silica or silicon dioxide, it has a hardness of 7 on the Mohs scale of mineral hardness and is one of the most important minerals of the earth’s crust, found in practically all types of rock.
At ASIA MINERAL MINES (AMM), quality quartz is formed as a by-product of the extraction and floating of kaolin. In our case, it is the so-called milky low-pressure quartz, with a whitish turbidity caused by the fine dispersion of air bubbles. It originates from the hydrothermal accompanying quartz and pegmatite (igneous rock) veins of the original acerbic granite, converted to kaolin by kaolinization.
Quartz is found not only as the main component of sands separated during kaolin flotation, but also as larger pebbles and stones from 2 to 10 cm of high-quality pure milk quartz with a quartz content of 98.5% or more, which is then sent for further industrial processing. The density of the solid is 2,600 kg / m3 with a measured radioactivity of 0.1 µSv (microsievert).
Industrial applications for DH QUARTZ include, synthetic quartz, semiconductor silicon, silicon alloys, photovoltaics, uses in the glassmaking industry, uses as industrial filler and abrasives, and more.
