Products India's No1 Alum Manufacturer, Supplier

A common method of producing potash alum is leaching of alumina from bauxite, which is then reacted with potassium sulfate. As a naturally occurring mineral, potash alum is known as alum-(K). Other potassium aluminium sulfate minerals are alunite (KAl(SO4)2·2Al(OH)3) and kalinite (KAl(SO4)2·11H2O).

Alunite Alum Stone Goldia

Oct 13, 2018 Alunite or alum stone is dominated by potassium and aluminum salts. Mineral deposits are formed in the surface layers of the soil under the influence of high temperatures typical of volcanic formations. Pure crystals with the formula KAL3 (SO4) 2 (OH) 6 are transparent, distinguished by white and gray shades. In some cases, sodium and iron can act as impurities, which paint alunite in red

Alunite Wikipedia

Alunite is a hydroxylated aluminium potassium sulfate mineral, formula KAl3(SO4)2(OH)6. It was first observed in the 15th century at Tolfa, near Rome, where it was mined for the manufacture of alum. First called aluminilite by J.C. Delamétherie in 1797, this name was contracted by François Beudant three decades later to alunite. Alunite crystals morphologically are rhombohedrawith interfacial angles of 90° 50', causing them to rese

ALUNITE (Potassium Aluminum Sulfate Hydroxide)

Alunite is also known as alumstone and is a source of the chemical known as alum, KAl(SO4)2 12H2O.Some alunite has also been used to recover potassium and aluminum. Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called "alunitization".The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals.

Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
