An ore deposit is a concentrated area of ores, and one that is profitable to mine. Geologists test properties of soil and rocks to locate ore deposits. In surface mining, the earth is blasted open, and rocks are taken to a refinery. This method includes open-pit mining, mountaintop removal, strip mining, placer mining, and dredging.

The ore is generally associated with Earthy impurities like Sand, rocks, and limestone Known as Gangue or Matrix. A substance added to ore to remove the impurities is called flux. The combination of gangue with flux in ores forms a fusible material called Slag. The concentration of ore is the process of eliminating gangue from the ore.

Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a ...
