2 Main Methods Of Extracting Metals From Their Ores

  • making metals

    the first stage in making metals is to mine the ore bearing rock. sometimes huge amounts of ore are needed to make a small amount of metal – most copper, for example, exists in sulphide ores that contain as little as 0.25% copper. the metal then has to be extracted from the rock using furnaces and electrolytic processes. finally, before the metal
