Non-explosive rock breaking: Mining all of the reef, all ...
South Africa's reef deposits, especially gold and platinum-bearing ore bodies, are narrow and tabular. While legislation dictates a minimum operation height of 800 mm in areas where people work, some of the country's narrow reef mines have ore bodies with thicknesses of less than 500 mm, which results in ore dilution, as waste ore with zero economic value is also mined.
