Abstract

Froth stability is very important as it affects both grade and recovery in froth flotation. It is desirable to control forth stability in several industries. In this research we aim to investigate the possibility of controlling froth stability and flotation performance through nanomaterials in flotation of complex sulfide ores. Face centered central composite design was used for design of experiments. Flotation was carried out via D-12 Denver flotation cell of 1-liter capacity. Al2O3 and SiO2 nanomaterials were used during the study. Addition of Al2O3 increased froth stability by about 20%.It also increased the grade and recovery of Pb by 40% and 4% respectively.SiO2 was not helpful in increasing froth stability. It was concluded that it is important to select correct type of nanomaterials for a specific ore. Correct type of nanomaterials can help increase dynamic froth stability and flotation performance.
