Abstract: The present disclosure discloses an application of cuprous sulfide in a recovery of Au (III) from aqueous solutions, which relates to the fields of hydrometallurgy and precious metal recovery. The method of the present disclosure uses cuprous sulfide nanoparticles to recover Au (III) from aqueous solution, and undergoes gold adsorption under mechanical stirring. The method described in the present disclosure can efficiently recover Au (III) from aqueous solutions, has good recovery effects on Au (III) from acidic waste liquid, and has the advantages of energy conservation, environmental protection, and low cost.

Abstract: A system for removing contaminants from emissions including a reverse venturi shaped fluidized bed device featuring a method for tilting and/or agitation. The system includes numerous component devices such as, but not limited to, an influent source, a fluidized bed device, a post filter device, and an effluent discharge, each of which are able to be isolated, integrated, bypassed, and/or reconfigured for application specific emissions requirements. The filter media is a mass of reactive material disposed within the fluidized bed which is in intimate contact with the emissions as they pass through the fluidized bed. The mass of reactive material contains an amalgam forming metal which chemically binds with the emissions that are passing through the system. Methods for removing contaminants from gaseous and non-gaseous emissions are also provided.

Other components by weight include manganese; cerium; carbon; phosphorous; sulfur; aluminum; silicon; chromium; copper; and zinc. Combined with layers of sand, brick chips and/or charcoal, the iron composition can be used to create a water filter for filtering inorganic arsenic species and soluble metal ions out of water. To enhance hydrous ferric oxide complexation and precipitation, the iron composition may be treated with food grade acids or a water mixture.

The sorbent body comprises an activated carbon matrix defining a plurality of pores, sulfur and an additive adapted for promoting the abatement of toxic elements from the fluid stream. At least one of the additive is formed into the sorbent body by in-situ forming such as in-situ extrusion. The sorbent is useful for abatement of, e.g., arsenic, cadmium, mercury and selenium from gas streams.
