Flotation - Mineral Processing Metallurgy

2016-1-11  The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

2014-12-1  1. Introduction. In the mineral processing industries, froth flotation is a common process for separation of the valuable from gangue minerals. Effective control of flotation circuits is a difficult task owing to several variables involved, unavoidable changes in ore characteristics and non-linear and dynamic nature of the process (Bonifazi et al., 2002).

Flotation of Metallurgical Grade Silicon and Silicon Metal ...

2017-8-24  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 HF conditioning time, frother type, and the concentration of both HF and frother. Although Brij 58 produced the highest recoveries of the frothers that was tested, good recoveries were ...
