  • Impact of calcium and gypsum on separation of scheelite

    15/05/2019· The impact of calcium and gypsum on separation of scheelite from fluorite using sodium silicate as depressant was investigated by micro-flotation tests, X-ray photoelectron spectroscopy (XPS), zeta potential measurements and solution chemical analysis. The flotation results confirmed that sodium silicate exhibited certain selective inhibition on fluorite. According to the XPS

    01/06/2015· These reagents are used in the industrial flotation of the copper–gold ore examined in this study. The gypsum (calcium sulphate dihydrate) that was added to the ore–clay mineral mixtures had a high purity (⩾99%), and was purchased from Sigma–Aldrich. Kaolinite Q38, sodium bentonite, and quartz were supplied by Sibelco Group, Australia.

    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%
