The obtained flotation concentrate contains 66.35%g/t gold and 37.06% S with recovery 96.14% and 96.42% respectively. A roasting process was conducted at 900-1000°C for 5.5hrs, followed by cyanide leaching of the residue.

Optimisation of gold recovery by selective gold

2001-2-1  GOLD FLOTATION Collectors The use of charged water soluble collectors such as xanthates and dithiophosphates slow down the rate of flotation of naturally floatable minerals, including native gold, at lower concentrations (Klimpel, 1997). Only the larger chained carbon groups (amyl and butyl) appear to be good gold flotation reagents.
