  • How do we extract minerals?

    In a surface mine, hard rock must be drilled and blasted, although some minerals are soft enough to mine without blasting. Placer mining is used to recover valuable minerals from sediments in present-day river channels, beach sands, or ancient stream deposits. More than half of the world's titanium comes from placer mining of beach dunes and sands. In placer operations, the mined
