Elements that Form Gypsum. Gypsum. Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate (SO4 2). The sulfate then bonds with calcium (Ca) and water (H2O) to create gypsum. Video of the Day.

You can obtain enough Gypsum fragments to craft up to eight …
It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.
