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

Apr 01, 2004 In the first experiment, pH measurements were made on a calcium sulphate (gypsum) slurry in presence of sodium bicarbonate (without aeration); in the second, pH measurements were made on a slurry of gypsum (25 g CaSO 4 · 0.5H 2 O per l) which was aerated (in a flotation cell); in the third, the pH of gypsum (10 g/l) slurry was set at 10 using

The interaction of clay minerals with gypsum and its

Jun 01, 2015 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.

This paper aims to understand the fundamental interaction mechanism between molybdenite and kaolinite in gypsum solution using kerosene as collector. Micro-flotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral. The results showed that the recovery of molybdenite decreased from 86% to 74%
