Barytes is also known as Barium Sulphate, Barites or Barite and derives its name from Greek and means heavy. It is a remarkable mineral which comes with a wide range of industrial applications because of its chemical properties. It is chemically inert and comes with high density and low oil absorption property.
Ancient man as early as the Stone Age, in his quest for knowledge and continued survival, started using various natural elements to craft tools. One such natural element would be pieces of volcanic glass (Obsidian) used to craft weaponry, as well as other distinct types of tools. Obsidian and sand stone were used by primitive man in the art of flint knapping. These were used for arrow tips, spears heads and hand-held skinning knives. It was this invention of tool making that began our fascination with various natural raw materials such bronze, steel and glass making.
Magnesium is recognized as an essential nutrient for all species. In humans, magnesium performs an extremely important role with numerous health benefits. This is an aftereffect of the lack of magnesium in the feeding cycle. The magnesium impoverishment in soils and plants, supply animals with deficient magnesium intake, resulting in diminished human intake.
In order to solve these problems and prevent magnesium deficiency, especially in lactating and grazing cattle and sheep it is essential to include some additional amounts of magnesium oxide (MgO, Calcined Magnesite) in their daily feeding.
Perlite is a volcanic rock formed when lava (molten rock) spews out of a volcano and cools in a rapid manner. Because of rapid cooling, water is trapped within the rock, and the lava forms into a glass-like structure.
There are many types of sand that one can use in moulding applications, from natural sands to man-made sands (such as ceramic sand). The purpose of sand as a moulding medium is to act as a good medium for high bonding mould strengths as well as provide a high refractoriness against heat. As a result, there will be fewer casting-related defects due to low refractoriness of the virgin sand.
South Africa is a country rich in mineral resources, one such mineral resource is foundry chrome sand. Optichrome foundry sand is a product designed to specifically to meet the stringent standards within modern foundries.
As Chinese authorities continue the clampdown on polluting industries to clean up local operations, the focus is shifting to magnesia processors. After the rapid downfall in magnesia prices out of China following the scrapping of the quota system, some suggest the downtrend may be reversed if the shutdowns lead to a supply shortage
