2023721 · Froth flotation is a commonly utilized beneficiation technique for effectively separating apatite from other gangue minerals, such as calcite. It is difficult to achieve good separation with fatty acid collectors due to their similar interactions with apatite and calcite. In this work, sodium N-lauroyl sarcosinate (SNLS) was used as the collector for the …

202421 · This paper presents a comprehensive study on the selective flotation of a multi calcium-bearing minerals ore, focusing on the efficient removal of dolomite and calcite impurities from a carbonaceous sedimentary phosphate ore. Commercial fatty acid (FA) and phosphate ester collectors were investigated in a reverse flotation process, assessing the …

202411 · The birth of froth flotation process took place with beneficiation of graphite after comminution [32]. Crushing and grinding of graphite to appropriate sizes are pre-requirement for this process. This process is based on the hydrophobic nature of graphite which can be selectively separated from hydrophilic minerals suspended in a water medium.
