Flotation stabilization and optimization SAIMM
Flotation stabilization and optimization implemented successfully at a level above the advanced stabilization Mintek’s re into flotation control began in the late 1980s when Mintek looked into the optimization of flotation circuits, particularly grade and recovery These tests involved xanthate addition and its effect on grade and recovery The Keywords flotation optimization, air rate, reagents, frother, froth depth, depressant * Anglo American Platinum © The Southern African Institute of Mining and Metallurgy, 2013 ISSN 22256253 This paper was first presented at the 5th International Platinum Conference 2012, 18–20 September 2012, Sun City, South AfricaA practical approach to plantscale flotation optimization Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA 1 Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et al, 2011)Flotation of NickelCopper Sulphide Ore: Optimisation of
A strategy for the identification of optimal flotation
The optimization process achieves the best solution by optimizing cell design, flotation circuit structure and metallurgical conditions The optimization process has three phases The first phase assumes that every flotation stage has the same residence time and calculates feasible flotation circuits, metallurgical conditions and cell volumesflotation are difficult to change in the industrial process eg: size of the flotation cells, impellers speed, retention time, variability of feed and others were kept constant For optimization the variables selected were pH, concentration of collector and concentration of frother The test results do not showedOptimization of Flotation for the Reduction of Heavy flotation process conducted in a Jameson cell was the subject presented in [32] To this end, we used taxonomic methods, which are an innovative approach to optimize the process Copper grade in concentrate (E), copper grade in tailings ( ), and copper recovery in a concentrate (H) were selected as factors for the evaluation of the flotation perMultidimensional Optimization of the Copper Flotation in
