Zicron Mining
Zircon is a non-metallic mineral with the chemical formula ZrSiO4. This mineral is commonly found contained in igneous rocks, metamorphic rocks and sedimentary rocks.
Zircon sand is a zircon mineral in nature in the form of sand. Zircon sand lies in Central Kalimantan and West Kalimantan, especially around rivers. In addition, zircon in the form of tin deposits is also widely found in Bangka Belitung.
The presence of zircon is usually found together with secondary deposits where the parent rock is deep igneous rock, secondary tin deposits in Bangka Belitung, and secondary gold deposits in Kalimantan.
Zircon Benefits:
Zircon is widely used in materials for the ceramic industry, refractories (furnace coatings or reactors that are high heat resistance), to dyes. The use of zircon in Indonesia is growing in a number of industrial sectors, including:
- Ceramic industry
- PSZ (Partially Stabilized Zirconia) glass industry
- Zircon flour industry (micronized zircon)
- Zirconium chemical industry
- Refractory brick industry
- Printing sand industry.
Properties and Characteristics of Zircon Sand
Zircon sand or zirconium silicate is a mineral that is corrosion resistant and has good stability at high temperatures. Zircon sand is not soluble in water but in an acidic solution. In addition, zircon sand can also precipitate in alkaline solutions.
Zircon sand can decompose at temperatures above 1,650 degrees Celsius. Generally, zircon sand contains elements of iron, titanium dioxide, alumina, hafnia, and other elements that cause the color of this mineral to vary, such as clear white, yellow, greenish, reddish brown, brownish yellow, and dark.
The characteristics of zircon sand in each place can be different. This is because the mineral impurities in zircon sand are strongly influenced by the initial process
