process for flotation of calcitefluorite ores
Selective flotation of witherite from calcite using ...
for calcite for the separation of fluorite and calcite. Fluorite and calcite could be separated effectively by flotation when the potassium chromate concentration was 9×105mol/L by using NaOL as the collector (Yu, 2015). The purpose of this study is to investigate the separation of witherite from calcite using potassium chromate as a depressant....

EXTRACTING METALS FROM SULFIDE ORES
The flotation concentrate contains sufficient copper for it to be suitable for smelting to recover the metal. Silver, gold and platinum group metals present in copper ores follow the copper in both the flotation circuit and the smelter, and are recovered in the final, electrorefining stage. Electrorefining is discussed in the final Section....

Mining and Beneficiation of Phosphate Ore | IntechOpen
Siliceous ores: these ores contain quartz, chalcedony or different forms of silica. Such ores could be upgraded economically by techniques such as flotation or gravity separation methods. Clayey ores: contain mainly clays and hydrous iron and aluminum silicates or oxides as gangue materials. These impurities could be removed by simple beneficiation techniques such as scrubbing and washing....
The effect of polyacrylic acid on the surface properties ...
In this study, the polyacrylic acid (PAA) was studied as a selective depressant for calcite in the selective flotation of fluorite and calcite, and the implications of this process for the separation of fluorite ore were studied using microflotation tests, and the results were analyzed with Fourier transform infrared spectroscopy (FTIR) and Xray photoelectron spectroscopy (XPS) analyses....
