how is gypsum ore removed from the gangue

Removal of gangue components from low-grade iron ore

The gangue in iron ore is removed by hydrothermal treatment to obtain the high-grade iron ore. • Removal extents of 10–91% for Si, 39–70-% for Al, and 38–76% for P are achieved by the treatment. • The FeOOH in iron ore changed to Fe 2 O 3 during hydrothermal treatment.

Why is gangue removed from an ore class 12 chemistry CBSE

Gangue is the unwanted material or the impurities present in the ore. It is commercially worthless. Gangue is the impurity that surrounds or is closely mixed with the ore deposit in which the minerals are present. Gangue is composed of waste rocks, stone and extra unwanted materials that are mixed up with the ore while its extraction.

gypsum ore stockpile - quates

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water.
