biotitic contains fine calcite grains along their cleavage planes giving a high content of calcite in the tailings. Fig.4: Biotitic, pyroxene and some opaques (sulphides like pyrite) surrounding the calcite grains Parallel light, x100. The basic principle in column flotation is the use of counter current flow of air bubbles and solid particles. This is achieved by injecting air at the base of

Calcite was primarily floated to avoid negative effect on the subsequent flotation of vanadium-bearing minerals, and then the tailing from calcite flotation was further subjected to direct flotation. The detailed process flowsheet is given in Fig. 1. Flotation products such as slime, concentrate and tailing were filtered, dried, weighed, and analyzed by XRF. Fig. 1 Process flowsheet

1/7/2018 Froth flotation has been used successfully over the last century for the beneficiation of coal and mineral particles. However, the process has been affected by certain restrictions relating to the rate at which the bubble/particle concentrate segregates from the aqueous tailings and to the recovery of ultrafine particles.
