Phosphate rock grinding mill Phosphate rocks are those minerals that contain the tetrahedral coordinated phosphate anion along with the freely substituting arsenate and vanadate. Chlorine, fluorine, and hydroxide anions also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common. Uses of Phosphate rock: 1. Phos... More

Potassium ore/Polyhalite micro powder grinding mill, grinder mill Polyhalite is an evaporate mineral, a hydrated sulfate of potassium, calcium and magnesium. Polyhalite crystallizes in the triclinic system although crystals are very rare. The normal habit is massive to fibrous. It is typically colorless, white to gray, although it may be brick red due to iron oxide inclusions. It has a Mohs hardne... More

Alunite grinding mill, Alunite grinder mill Alunite is a sulfate mineral, it occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks. It is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide deposits. Alunite also is found near volcanic fumaroles. The white, finely granular masses... More

Steatite is also known as soapstone or soap rock. Steatite is relatively soft (because of the high talc content, talc being one on Mohs hardness scale), and may feel soapy when touched, hence the name. Steatite is a metamorphic rock, and it is composed dominantly of talc, with varying amounts of chlorite and amphiboles. The hardness of steatite will increase after calcined, when heated to temperat... More

Cocoanut shell activated carbon is widely used in domestic water, industrial water and wastewater deep purification and gas adsorption, such as petrochemical, power plants, food and beverage, sugar the wine, medicine, fish industry, water purification process, the effective absorption of water of free chlorine, phenol, sulfur and other organic pollutants, in particular, is a precursor of mutagens (...

Chromites are also called chrome iron ore, or chromic iron ore. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite; substitution of aluminium occurs leading to hercynite. Chromites should be crushed or pulverized to grain or powder after mined and separation. The common pulverizer and crusher... More

Emerald micro powder grinding mill industries in Zambia Emerald is a variety of the mineral beryl colored green by traces amounts of chromium and sometimes vanadium. The emerald deposits of Zambia in the Kafubu River, about 45km southwest of Kitwe, produced around 20% of world production of gem quality emeralds. According to one legend, in the middle ages, the emerald ground into powder, used to st... More

Hornblende is black and, like all amphibole minerals, is characterized by two perfect cleavages that intersect at about 60 or 120. Instead of breaking in broad, single cleavage planes like the micas, the cleavage surface of an amphibole mineral tends to display a large number of small, offset planes that help give the mineral a splintery appearance. The large number of small offset cleavage planes... More
