    Abstract: A composition and process are provided for the recovery of the values of zinc, molybdenum, copper, lead, iron (pyrite), and iron-containing small amounts of gold or uranium, or both, from ores comprising these mineral sulfides. The aqueous composition is the impure form of an alkali metal alkyl trithiocarbonate compound. The process comprises employing said aqueous composition as a collection agent for the above minerals in an ore recovery process.A process for the separation of zinc values from lead values from an ore comprising both is provided by employing an alkali metal alkyl trithiocarbonate compound as a collection agent for zinc.In addition, both a composition and process are provided for the recovery of the values of iron, copper, and lead from ores comprising these values. The composition consists essentially of a dispersant and an impure form of an alkali metal alkyl trithiocarbonate compound. The process comprises employing this composition as a collection agent for the above minerals in an ore recovery process.

    Abstract: Cost effective and environmentally acceptable reagents and a method for flocculating fine particles from liquid suspensions are provided. A method for selectively flocculating fine particles from a slurry is also provided. The reagents comprise orange peel extract, corn husk extract and mixtures thereof. The method generally comprises the step of adding a reagent to a suspension of fine particles, mixing the combination of reagent and suspension and allowing the flocculated fine particles to settle out of suspension.

    Abstract: A process for separating molybdenite from copper and iron ores is disclosed. A copper concentrate containing molybdenite is treated during an attritioning stage with a surfactant which is an alkyl ester of sodium and/or calcium succinic or succinamic acids and a molybdenite concentrate is recovered by flotation. The molybdenite concentrate contains at least 90% of the original molybdenite and less than 5% of the undesirable ores.

    Abstract: Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.

    Abstract: Disclosed herein is a method for separating an arsenic mineral from a copper-bearing material, including the steps of grinding a copper-bearing material containing arsenic, adding water to the copper-bearing material to prepare a slurry, and adding a flotation agent including a depressant, a frother, and a collector to the slurry and blowing air into the slurry for performing flotation to obtain a copper concentrate, wherein the depressant is a chelator. As the chelator, a polyethyleneamine or the like is used. Particularly, when triethylenetetramine is used as the chelator, the amount of triethylenetetramine to be added is preferably 1 to 10 equivalents relative to the amount of soluble copper generated by oxidation of the copper-bearing material, and the pH of the slurry is more preferably adjusted to 7 or more but 8 or less before the slurry is subjected to the flotation.
