Influence of reagent dose on the flotation selectivity of copper ore from LGOM area(SW Poland)

摘要

The influence of amount of flotation reagents on the efficiency of copper ore flotation in standard laboratory experiments was investigated.The aim of the study was to evaluate the effect of collector and frother amount on the selectivity of copper upgrading during flotation process of dolomite-shale ore from Fore-Sudetic Monocline area(Legnica-Glogow Copper Basin).The amount of collectors added in industrial conditions was the starting point for the process assessment.Since the dose of flotation reagents influences on the quality and quantity parameters of obtained concentrates,a decrease or increase of reagent dosage can have a major impact on the overall metal production costs at the mining-metallurgical complex.
