Mining Gold Ore Flotation Process In India

sulphide gold ore treatment by leaching and flotation process,the second flowsheet is another application of flotation as applied to a gold ore. in this case the flotation tailings are cyanided for gold recovery. the jig is again employed in the grinding circuit as in gold flowsheet no. 1 for the same reasons. this scheme would be used where it is not possible to make a flotation tailing low enough in gold to be discarded but flotation is warranted for one of the following.quartz vein type gold ore and sulfide gold ore,gold ore,most gold-bearing sulfide ores can be processed by flotation, and some can also be processed by cyanidation, or combined methods, or amalgamation, gravity separation, or combined processes. the choice of flotation or cyanidation process depends on the recovery rate of gold and the degree of comprehensive utilization of associated minerals. if the ore contains more coarse gold, it.improved recovery of a low-grade refractory gold ore using,in addition, the bulk flotation method resulted in the concentrate with low concentrations of sb and as elements. to improve the recovery of low-grade refractory gold ores, flotation should be followed by roasting, biological, or pressure oxidation processes so that the gold could be liberated prior to cyanidation processes..flowsheet development for gold orebodies,economic cut-off gold grade for refractory ores is somewhat higher than non-refractory ores. the mining industry uses a “rule of thumb” of 80% gold recovery to define the transition from a refractory to a non-refractory gold ore. ones under 80% are considered refractory. in assessing the economic benefit of the extra processing.
