    Dec 06, 2019· Ores are collection of minerals containing one or more metals [4] [5]. These metals are economically and conveniently extracted from these ores by following certain extraction techniques. The reason behind presence of metals in form of ores and minerals is that, most of metals being highly reactive, cannot exist in free form [6].
