  • The Use of Radiotracers to Locate and Eliminate Gold

    "Free gold particles occur in many base metal and precious metal mines throughout the world Occasionally mine operators are unaware of the presence of free gold particles in their ores because they have not seen free gold hand specimens or at the working face of the mineDue to the high density and malleability of gold, large circulating loads of free gold particles can build up over time inSAG mills, rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding The most common type of rod mill is the overflow mill There are two typed of ball millsGold Extraction & Recovery Processescoarse gold from conventional grinding circuits these circuits are often designed so that the grinding mill output is size classified, with large (or high density) particles being removed before the tails are returned to the mill because of the high relative sg of gold, and the fact that some forms of gold such as free gold do not break apartCoarse gold reCovery using flotation in a fluidized bed
