  • What are the main methods of mining? | American

    There are four main mining methods: underground, open surface (pit), placer, and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsTo isolate pure gold, mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller pieces At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel The gravellike material then enters rotating drums filled with steel balls In these drums, the ore is ground to a fine slurry or powderExtracting Gold | HowStuffWorksThe Chemistry of the Extraction of Gold MJ Nicol, CA Fleming and RL Paul 1S1 General Principles 1511 The chemistry of gold compounds Gold is the most noble of all the metals and this is the key to both its eternal romance and its many practical uses in industry It is the only metal, for example, that is not attacked in air or water by either oxygen or sulphur, and its durabilityThe Chemistry of the Extraction of Gold SAIMM

  • Metal extraction and the reactivity series The

    The method used to extract a metal from its ore depends upon the stability of its compound in the ore, which in turn depends upon the reactivity of the metal Therefore, the method of extractionFor the extraction of highly reactive metals from their ores electrolysis is used and for extraction of metals of medium reactivity calcination, roasting and reduction methods are used While metals of low reactivity are extracted from their ores by roasting and refining Although mostly low reactive metals are found in free states such as the gold is generally found in free state or withOres and Minerals Introduction, ExtractionHowever, extraction of gold also has different gold leaching methods, but generally, it uses gold leaching methods such as gold ore gravity separation, gold ore magnetic separation, gold ore flotation separation, gold ore amalgamation, gold ore cyaniding and the latest resin pulp separation, carbon paste adsorption as well as dump leaching Inquire Now; method used to extract gold from its oremethods of extracting gold from ore
