Gravity Concentration an overview ScienceDirect

In the various gold rushes of the nineteenth century, many prospectors used gold panning as a means to make their fortune—another ancient method of gravity concentration. Gravity concentration, or density-based separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of low-grade complex ores.

An enhanced gravity concentration flowsheet was tested, which began by screening the residue into three size fractions: +180 μm, 180–53 μm and −53 μm. The 180–53 μm fraction was treated with a spiral as a roughing unit and then a shaking table as a cleaning unit, whereas the fine −53 μm processing is addressed in the third publication.
