    摘要: A continuous flow reactor for the efficient synthesis of nanoparticles with a high degree of crystallinity, uniform particle size, and homogenous stoichiometry throughout the crystal is described. Disclosed embodiments include a flow reactor with an energy source for rapid nucleation of the procurors following by a separate heating source for growing the nucleates. Segmented flow may be provided to facilitate mixing and uniform energy absorption of the precursors, and post production quality testing in communication with a control system allow automatic real-time adjustment of the production parameters. The nucleation energy source can be monomodal, multimodal, or multivariable frequency microwave energy and tuned to allow different precursors to nucleate at substantially the same time thereby resulting in a substantially homogenous nanoparticle. A shell application system may also be provided to allow one or more shell layers to be formed onto each nanoparticle.

    摘要: A synthetic method of fabricating highly crystalline and uniform nanoparticles of metal sulfides, doped metal sulfides, and multi-metallic sulfides disclosed, using no-toxic and inexpensive reagents. A typical synthetic method comprises the steps of, synthesis of metal-surfactant complexes from the reaction of metal precursors and surfactant, addition of sulfur reagent to the solution containing said metal-surfactant complexes followed by heating to high temperature, aging at that temperature to produce metal sulfide nanoparticles and completing the formation of synthesis of nanoparticles metal sulfides and multi-metallic sulfides by adding a poor solvent followed by centrifuging.

    摘要: A method is provided for the removal of lead contaminants from ores and mineral concentrates, comprising leaching the concentrates, at elevated temperatures, with an aqueous solution containing an aminopolycarboxylic acid. After separating the solution from the concentrates, lead can be precipitated by treating the solution with a sulfide; the solution can be recycled for use as a leachant.

    摘要: Lead constituents may be removed from a dross to produce a copper matte low in lead assay by melting the dross at temperature in excess of 900.degree. C., allowing the molten dross to separate into a lead bullion layer and a matte layer, removing the lead bullion layer from the matte layer, then heating the matte layer to a temperature in excess of 1000.degree. C., and removing the lead sulphide therefrom as a fume.
