Experimental Study on Beneficiation of a Gold Mine in Shandong Province
Taking a gold mine in Shandong as the research object,a gravity concentration-flotation combined process can be used to obtain a gold concentrate with a gold grade of 88.18 g/t,a recovery rate of 17.00%,a silver grade of 16.28 g/t,and a recovery rate of2.01%.Additionally,a flotation gold concentrate with a gold grade of 55.59 g/t,a recovery rate of 76.28%,a silver grade of 89.96 g/t,and a recovery rate of 79.11%can be obtained.The gold grade of the total concentrate is 59.60 g/t,with a gold recovery rate of 93.18%,a silver grade of 80.89 g/t,and a silver recovery rate of 81.12%.The gold mine adopts a gravity concentration-flotation combined process,which can effectively recover cash and achieve comprehensive recovery of associated metal silver.This study can achieve comprehensive and effective recovery of gold and silver resources,providing important guidance for the recycling and utilization of this type of gold resources.
