In the flotation of samples containing gypsum adjusting and maintaining the pH above 8 requires a large amount of base. The pH of the slurry when above 8 decreases when the pulp is aerated as in flotation. To counter, a large amount of lime or other base (for example, sodium carbonate) is …
Utilisation of FGD gypsum for silicate removal from ...
FGD gypsum is produced from the process of wet limestone flue gas desulfurization. Many steelworks, smelting plants and coal-fired power plants adopt this approach to control emissions of sulphur dioxide because of its high desulphurization performance, reliability and low-utility consumption [16], thus generating high amounts of FGD gypsum [17].

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% ...
