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: One or more surfactants and one or more adjuvant gases in the hydrometallurgical and pyrometallurgical processes, which are added thereto in the state of nanobubbles and microbubbles, both the gases used and the nanobubbles and the microbubbles thereof, are in a variable proportion depending on the physicochemical requirements of each of the stages of the process where it is applied. The nanobubbles and microbubbles, of the proposed composition, make it possible to significantly increase the physicochemical properties of these gases such as: flotation speed, oxidizing power, reducing power, contact area provided and coalescence speed.

Abstract: A process for treating oil sands process-affected water containing contaminants, including dissolved organics is provided, comprising: injecting a foaming gas into an oil sands process-affected water to generate an organics-enriched foamate and treated water; and removing the organics-enriched foamate from the treated water to remove contaminants, including at least a portion of the dissolved organics from the treated water.

Abstract: A stabilization process for an arsenic solution comprising thiosulfates, the process comprising: acidifying the arsenic solution to decompose the thiosulfates, to yield an acidified solution; oxidizing the acidified solution to oxidize residual As3+ to As5+ and reduced sulfur species to sulfates, to yield a slurry comprising elemental sulfur; separating elemental sulfur from the slurry to yield a liquid; oxidizing the liquid to oxidize residual reduced sulfur species, to yield an oxidized solution; and forming a stable arsenic compound from the oxidized solution.
