Taramani Chennai 600 113, India Received 22 August 2002; accepted 15 April 2004 ABSTRACT Beneficiation of a low grade gold ore was studied by column flotation. The quality of the concentrates obtained by flotation column was found to be much superior compared to that of conventional flotation cells.
Flotation of Sulphide Ores HZL Experience. V.P. KOHAD Hindustan Zinc Ltd., Zawar Mines, Udaipur 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants. This technology has acclaimed importance as a versatile process for the beneficiation of vast variety of sulphide minerals.

Abstract. Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.
It was describe by the use of 600 series of flotation reagents which were developed primarily for the purpose of depressing carbonaceous and siliceous slimes in the flotation of gold ores. Carbonaceous material not only greatly increases the bulk and moisture content of a flotation concentrate, but its presence makes cyanidation of the concentrate difficult or impossible owing to reprecipitation of the gold during treatment.
assignificant quantities ofuranium and gold are also recovered intheflotation, these processes areconsidered later. The fact that pyrite isnormally floated after gold recovery leads tothe most interesting aspect ofpyrite flotation. Cyanide isinherently adepressant forpyrite, and the traces of cyanide present in the gold plant
Starting with ore containing 1.4 g/t of gold, it has been possible to generate a sulphide concentrate with 6.1 g/t of gold by physical beneficiation of the ore through froth flotation. Thiourea leaching of this flotation concentrate after pressure, pre oxidation has resulted in gold extraction of 98%, with an overall gold recovery of 74%.
Because of the weak metal bonding force, the native gold has the characteristics of small surface wettability and easy to float. The production practice shows that the native gold and many heavy metal sulfide belong to the floating minerals,it39;s easy to be collected by Xanthate Flotation Collectors.
