摘要： The present disclosure relates to a method for recovering gold in a cyanide tailing by hierarchical ramified flotation. The present disclosure divides a cyanide tailing into coarse and fine-grained products through screen classification, making preparation for hierarchical ramified flotation. The present disclosure 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 present disclosure 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 present disclosure has an advanced process, a good separation effect, and can effectively recover fine-grained gold in the cyanide tailing.

摘要： Methods for niobium concentration from a carbonatite host rock are presented. A basic process for niobium mineral concentration involves performing niobium mineral flotation, on a sufficiently liberated ore slurry, using at one least aromatic hydroxamate collector; and at least one lead salt as a performance modifier. A more optimized process further includes dispersion. A further optimized process includes: magnetic separation, dispersion, sulphide removal, fine suspended particle removal, and niobium cleaner flotation stages. The use of one of number of tested lead salts during flotation improves the yield, and lowers the cost as a significantly lower amount of the collector is required. The process is useful for recovering a variety of species of niobium minerals such as fersmite, pyrochlore, columbite, fergusonite, niobium-containing rutile, and niobium-containing ilmenite.

摘要： There is provided methods for separating a target material from a raw material by mixing the raw material with water to form a slurry, adding a collector compound to the slurry to modify a relative hydrophobicity of a surface of the target material, adding a facilitator compound to enhance the modification of the relative hydrophobicity of the surface, and forming a froth including a concentrate of the target material. Disclosed methods may also include adding a facilitator compound to a raw material slurry that has been treated with a collector compound and a reagent for neutralizing the collector compound.

摘要： Apparatus is providing featuring a synthetic bead having a solid-phase body with a surface, and being configured with a predetermined electric charge so as to respond to a corresponding predetermined electric field; and a plurality of molecules attached to at least part of the surface, the molecules comprising a functional group selected for attracting and attaching one or more mineral particles of interest to the molecules. Some combination of the solid-phase body or the surface may be configured from a polymer. The polymer may be polyethylenimine. The polyethylenimine may be engineered or configured to be highly charged so as to be used to collect the mineral particles of interest and then manipulated through and by the corresponding predetermined electric field.

摘要： The invention resides in the use of a bacterial cellulose as a depressant for readily flotatable silicate minerals in an ore flotation process. Depending on the particular ore being treated, from 0.2-1.5 lb/ton of ore of the bacterial cellulose is effective as a talcose mineral depressant. Usually only about 0.10-0.25 lb/ton of the bacterial cellulose will produce optimum results.
