metal ores process

  • Smelting - Wikipedia

    Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

  • Roasting (metallurgy) - Wikipedia

    Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores.More specifically, roasting is often 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 ...

  • What is biomining? | American Geosciences Institute

    Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them
