Gypsum utilization on selective reduction of limonitic
The results indicate that gypsum can provide a selective effect on the direct reduction process of laterite nickel ore. A selective effect that lowers the grade of iron can occur due to the formation of iron sulfides. The use of 12% gypsum was able to produce a product with Ni grade of 4.13%, Ni recovery of 91.81%, and selectivity factor of 5.72.

The Basics of Drying Gypsum
The Role of Drying in Gypsum Mineral Processing. After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. If the gypsum ore’s moisture content is greater than 0.5 weight percent, then the material requires drying. A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.

Beneficiation of Raw Gypsum Ore
This process is used because it does not require electricity or water to run. Sieving is used to separate particles by size. The calcium bentonite clay in the raw gypsum ore has a particle size of ~1-5 µm, whereas the gypsum and quartz have a particle size of ~1-2 mm. Therefore, the calcium bentonite clay can be separated through sieving.

Is Gypsum A Ore
Gypsum in its natural state is an ore often found layered with limestone. It is liberated from its natural state most commonly by surface mining. Further processing includes drying the ore to remove excess moisture, then grinding it into a fine powder known as land plaster.
