Abstract

See full text

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.
