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

Prediction of the metallurgical performances of a batch

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).

Srdjan M. Bulatovic, in Handbook of Flotation Reagents, 2007 Processing characteristics of a massive sulfide ore. When using a conventional flotation reagent scheme and flowsheet, only a few of these ores respond (i.e. lime + NaCN + collector), giving extremely poor metallurgical results. The majority of these ores require a specific treatment process to achieve satisfactory metallurgical results.
