grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called ‘beneficiation.’ milling is one of the most costly parts of beneficiation, and results in very fine particles that allow better extraction of the metal. however,
the mining sector covers the extraction and processing of metals and mineral ores and deposits, including coal, copper, iron, limestone, nickel, precious metals, potash, uranium, diamonds, minerals, rare earth elements, and much more. the mining platform identifies mine type (above-ground, underground and solution) and mining method.
