2020-5-16When an ore has a low percentage of the desired metal a method of physical concentration must be used before the extraction process begins. In one such method the ore is crushed and placed in a machine where by shaking the heavier particles containing the metal are separated from the lighter rock particles by gravity

2020-4-16Terminology Metallurgy The scientific and technological process used for isolation of the pure metal from its ores is known as metallurgy. Depending upon the nature of metal and the nature of ore different methods are used in the extraction process
2. The concentration of ores The process of removing impurities from ore is known as a concentration of minerals or ore dressing. In metallurgy we concentrate the ores mainly by the following methods. 3. Hydrolytic method In this method we pour the ore over a sloping vibrating corrugated table with grooves. A jet of water is allowed to
Concentration of the Ore. When an ore has a low percentage of the desired metal a method of physical concentration must be used before the extraction process begins. In one such method the ore is crushed and placed in a machine where by shaking the heavier particles containing the metal are separated from the lighter rock particles by gravity

2020-5-7Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal components. Often before roasting the ore has already been partially purified e.g. by froth flotation
