    13/07/2016· REAGENTS USED IN FLOTATION OF GOLD ORES Conditioning agents are commonly used, especially when the ores are partly oxidized Soda ash is the most widely used regulator of alkalinity Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold18/04/2016· The calcine is then quenched, ground and returned to the plant In fact, flotation has made possible the treating of such ore bodies for the recovery of gold It was never possible to treat these direct by cyanide and difficult to roast ore alone because of the large amount of extraneous heat required Flotation concentrates are usually selfroasting One particular plant uses a flowsheet similar to No 2 Here flotation concentrates are reground The flotationSulphide Gold Ore Treatment by Leaching and Flotation Process06/02/2018· Froth flotation works by exploiting the hydrophobic properties of gold molecules First, ore is ground into an extremely fine powder The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity This mixture is placed into a large tank filled with distilled water Air bubbles are pumped into the tank and the water is agitatedRecovering Gold through the Froth Flotation Process

    23/07/2014· In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity This mixture is placed into a tank or flotation cell filled with distilled water Air bubbles are pumped into the flotation14/07/2016· The later development of flotation for gold ores, has, in most cases, provided a satisfactory pretreatment and has been applied in several ways Flotation removes most of the freed carbon with the concentrate, which is then roasted prior to cyanidation or shipped to a smelter McIntyre, using flotation with cyanidation of concentrate, refloated their cyanidation tailing and returned thisRefractory Gold Ore Treatment MethodsThe present paper describes the beneficiation of lowgrade gold ore by flotation columns and the implications of improved metallurgy on subsequent cyanidation 2 EXPERIMENTAL 21 The gold ore The mineralogical assay of gold ore revealed that the ore is semirefractory containing both free and refractory gold approximately in the ratio of 80:20 About 8590% of gold was locked in arsenopyrite andFlotation and cyanidation of a semirefractory gold ore
