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: A process is provided for separation of at least one metal sulfide from a mixed sulfide concentrate. The process includes: subjecting the mixed sulfide concentrate to flotation in which at least one sulfide including antimony, arsenic and a first metal is floated and at least one sulfide including a second metal is depressed. The flotation yields a first metal concentrate having the at least one sulfide including antimony, arsenic and the first metal and a second metal concentrate having the at least one sulfide including the second metal. The first metal concentrate is leached to yield a further concentrate and a leach solution. The further concentrate includes the first metal and the leach solution includes soluble antimony and soluble arsenic. The process further includes oxidizing the leach solution to yield an antimony precipitate and an arsenic solution, and forming a stable arsenic compound from the arsenic solution.

Abstract: A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell, is dried to produce a manganese concentrate, and is sintered to produce a synthetic manganese oxide. Sintering of such concentrates at 1000.degree. C. yields a product containing greater than 50% manganese.The effect of reagent dosage, pH control, and temperature control on the yield of the synthetic manganese oxide is also disclosed.
