  • Roasting (metallurgy) Wikipedia

    Roasting is a process of heating of sulfide 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 gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

  • Introduction to Mineral Processing

    Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

  • Refining Process Against Impurities Chemistry

    Zone refining: Metals such as germanium, silicon, gallium, indium and boron are made free from impurities using this method.In this process the impure metal is attached to a circular mobile heater at one end. As the heater is moved, the pure metal crystallizes out and the impurities pass on to the adjacent part of the metal.
