Abstract: Provided is a method for recovering gold in a cyanide tailing by hierarchical ramified flotation. The method divides a cyanide tailing into coarse and fine-grained products through screen classification, making preparation for hierarchical ramified flotation. The method then conducts flotation of the coarse and fine-grained products with suitable process parameters and reagent systems, and selects a suitable coarse-grained flotation product as a carrier of fine-grained flotation to maximize the recovery efficiency of fine grains. The method improves the overall recovery rate of gold with the hierarchical ramified flotation of coarse and fine grains, series-carrier flotation and combined reagent enhanced flotation. The method has an advanced process, a good separation effect, and can effectively recover fine-grained gold in the cyanide tailing.

Abstract: The invention provides methods and compositions for improving a froth flotation type separation. The method uses a thickener to improve the effectiveness of an emulsifier. The improvement allows for low dosages of emulsifier to work well so the emulsifier does not cancel out the effectiveness of other additives in the slurry such as collectors, frothing agents, regulators, depressors, deactivators, and/or activators.
