However, the low grade and fine size range of the metal-bearing minerals make their recovery difficult using unique gravity concentration methods. An enhanced gravity concentration flowsheet was tested, which began by screening the residue into three size fractions. The 180–53μm fraction was treated with a spiral as a roughing unit and then ...
