Research and Reports on Metals

An ore is a special type of rock that contains a large amount of a particular mineral (usually a metal) to make it economically practical to extract that mineral from the surrounding rock Ores can be mined in a number of ways including strip mining Ores are classified based on how they form like magmatic or volcanic ores Carbonate alkaline
