small and medium scale gold ore processing

This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration The flowsheet is ideal for a pilotplant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore

In many countries elemental mercury is used in artisanal and smallscale gold mining Mercury is mixed with goldcontaining materials forming a mercurygold amalgam which is then heated vaporizing the mercury to obtain the gold This process can be very dangerous and lead to significant mercury exposure and health risks
