Froth Flotation Method For Sulphide Ores In United Kingdom

aspects of froth flotation for a stibnite ore from Xikuangshan and some other locations in China (Hu, 1988; Anderson 2012). On the basis of the aforementioned considerations and to the best of the authors’ knowledge, a comprehensive and updated assessment focusing on key aspects of the froth flotation of stibnite ores is still

    Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation

    Flotation of mixed oxide sulphide copper-cobalt minerals

    Jul 01, 2019 While flotation is a common method to concentrate sulphide ore in the DRC, oxide ore requires sulphidisation prior to flotation with xanthate collectors (Crundwell et al., 2011). The flotation of sulphides and sulphidised oxides must be done separately as reagents used for sulphidisation of the oxide minerals will cause depression of sulphide

    what is the role of depressant in froth floatation process

    However, sometimes the ore we are using also has other sulphides present in it as impurities. For example, lead sulphide generally has zinc sulphide also present as impurity which will also float in the froth floatation process along with the lead sulphide. To make sure that lead sulphide floats but zinc sulphide do not float, we add depressants

    The process is best suitable for sulphide ores. The process is based on different wetting characteristics of the ore and gangue particles with water and pine oil. The ore is wetted by oil and impurities are wetted by water. Ore particles are adsorbed on potassium or sodium ethyl xanthate (as a collector) and come at the surface along with the froth
