explain the froth floatation process askiitians

This process is called concentration of ore. This process is mainly used for sulphide ores. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. In this process, a suspension of a powdered ore …

sulphide ore is concentrated by the method 1. froth

The method is based on the different wetting characteristics of the gangue and the sulphide ore with water and oil. The gangue preferrentially wetted by water and the ore by oil. The crushed ore along with water is taken in a floatation cell. Various substances are added depending on the nature of the ore and a current of air is blown in

Flotation is one of the first steps in the concentration of the valuable sulphide minerals [6,7,8]. Xanthates are the most common collectors used to concentrate DRC ores with typical recoveries averaging around 85% for copper and 60% for cobalt, and concentrate grades consisting of up to 45% Cu and 4% Co [ 8 ]

4. Flotation-roasting-cyanidation leaching process for high-sulfide gold ore. The symbiotic relationship between gold and sulfide in high-sulfide gold ore is close, and most of the gold is wrapped in sulfide, so the gold recovery rate of direct leaching will be extremely low. In addition, the consumption of gold leaching reagent is large, so as the cost of direct leaching of raw ore. Therefore, it is not appropriate to do high sulfide …
