The present study presence the potential of nano inorganic based frothers for the flotation of PGMs. Froth flotation is one of the oldest mineral processing technologies, initially invented 115 years ago for the treatment of sulphide (copper, lead and zinc) ores.

7 Citations. Explore all metrics. Abstract. Flotation experiments performed on metallurgical grade silicon have demonstrated that silicon (Si) can be floated in diluted solutions of hydrogen fluoride (HF) and a frother. The recovery was found to depend on …

Silica sand or quartz sand, its main component is SiO2 and the content below 98.5% is called silica sand. High-purity silica sand that meets the requirements is often obtained by mineral processing and purification, including washing and desliming, magnetic separation, gravity separation, flotation and other combined processes.
