  • Gold mineral processing Hatch Ltd

    The world's gold production has changed over the past 30 years. The exploration and discovery of large, free milling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, low grade deposits or look for smaller, often more complex ones in remote, often hard to reach locations?
