Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name "gypsum" is derived from the Greek word "gypsos," which means "plaster" or "chalk.".

One main source of nickel besides nickel sulfide ore is laterite nickel ore. Laterite ore is more sustainable and has abundant reserves. Nowadays, nickel demands are increasingly needed either for the manufacture of stainless steel or nickel-based batteries. This study aims to study the smelting process of limonitic laterite nickel ore. The smelting …

Rare earth elements are widely found in many minerals, some of which, such as bastnaesite, monazite, and xenotime, are of great commercial value. Cerium (Ce) is the rare earth element with the highest content in light rare earth ore. Solvent extraction is the most effective and efficient method to recover and separate Ce from other light rare earth …

The price of gypsum powder is generally calculated in tons. Its price varies with its accuracy and use. The price of gypsum powder is between $28.8-$403.6 per ton according to its whiteness and fineness. …

Abstract. The celestite ore from Sivas, Turkey which was subjected to this experimental study contained mainly celestite and gypsum as gangue minerals. …

When dehydration occurs, gypsum (CaSO 4 ·2H 2 O) may transformed to plaster of Paris (hemihydrate mineral: CaSO 4 ·O·5H 2 O), which usually leads to structural failure [33,44]. This shows that the existence of water molecules in the rock structure may help ore response to thermal treatment. ... Dash et al. (2019) demonstrated that thermal ...

Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in portland cement. Varieties of gypsum known as "satin spar" and "alabaster" are used for a variety of …

A 300 g mass of gypsum concentrate was added to the 1.0 L flotation tank. Distilled water (1.0 L) was added, and the pulp was stirred and mixed for 3 min, followed by adjustment to the required pH using sulfuric acid. After 5 min of pulping, the depressant was added to the slurry and conditioned for 3 min.

1. A method for separating a suspension containing gypsum granules, calcium carbonate granules and an aqueous solution, wherein the aqueous solution comprises at least one sodium salt and wherein the aqueous solution has a sodium ion concentration of at least about 3 g/L, said method comprising: a step of separation of …

Arsenic (As)-bearing gypsum sludge, one of the biggest As-bearing wastes, has seriously threatened ecological security due to the great mobility and leaching toxicity of As.Unfortunately, most of this sludge was discharged into tailing ponds without treatment. In this paper, a novel co-process of As-bearing gypsum sludge, waste carbon cathode …
