Separation of Gypsum by the Flotation Process

Especially, from the views of separation and recovery of gypsum, the following treatment would be recommended which the concentrates risen by flotation were well washed by water, because of the greater solubility of such coexisting salts as NaCl, MgSO 4, MgCl 2 and so on than that of gypsum

2015-6-1  Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

Gypsum - Chemical Formula, Properties, Types, Uses and

Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
