to acceptable rates of gold recovery at the sluices, and when sands with the presence of fine and fine gold are mined, losses increase even more To reduce the loss of gold on the devices of the Derokertype, a scheme was tested with the division of the flow of deep filling sluices (DFS) into two flows: oversize and undersize (Fig 1)4 Regrinding process of gold ore The regrinding process is mainly to disentangle the gold mineral and obtain higher grade final gold concentrate It is to regrind the coarse concentrate obtained after coarse selection, and the process adopts a closedcircuit grinding process Use overflow ball mill to grind coarse concentrate to0043mmA HardtoSeparation Gold Beneficiation Process and Equipment
Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes The choice among these processes depends on the mineralogical characterization and gold content of the ore Recently, the recovery of gold using gravity methods has gained attention because of low cost and Introduction Froth flotation is the largest tonnage separation in mineral processing by which valuable mineral is separated from waste rock Advances in control and optimisation of the froth flotation process are of great relevance since even very small increases in recovery lead to large economic benefits (Ferreira and Loveday, 2000, Modelling for froth flotation control: A review ScienceDirect
Therefore, in this work, the initial sample corresponds to the product of gravimetric concentration using Jigs, which was subjected to free gold recovery processes; these waste sands were used as feed material in the monazite beneficiation process A total of 1400 kg of sample was well mixed and homogenized for further concentration Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ) Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 )Beneficiation of Gold and Silver Ores SpringerLink
