    摘要: 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.

    摘要: To enable high-added-value low-specific-gravity hollow particles to be efficiently mass-produced by using, as a raw material, coal ash discharged when coal is combusted; enriching low-specific-gravity hollow particles contained in the raw material coal ash by classification to reduce the weight of the coal ash to be subjected to wet specific gravity separation; subjecting the raw material coal ash which have been reduced in weight to wet specific gravity separation to obtain low-specific-gravity components; and dehydrating and drying the low-specific-gravity components.
