Method and technique employing a novel extractant to enhance recovery of gold and palladium from hydrochloric acid media

An extraction component enabling the concurrent recovery of gold and/or palladium selectively from a hydrochloric acid media containing the base metals and other contaminants. The disclosed extractant disclosed eliminates the conventional multi-step process for such extraction by providing for an extraction method which uses a single solvent extraction reagent. Further enhancing the conventional multi step process, the conventional scrubbing stage is eliminated by a single stripping stage. The resulting solutions can be obtained from leaching many types of material such as copper anode slimes, the treatment of scrap such as electronic circuit boards and plating effluents, PGM, or refractory gold ores.

Noble metal-oxide joined nanoparticles and method for high-purity production of the same

Provided is a clean production method of: producing, with good reproducibility, a composite nanoparticle, which has one high purity noble metal nanoparticle combined with one oxide nanoparticle; and being capable of generating a heterointerface uniformly, with avoiding, for example, residual poisoning substances. Characterized is that a composite nanoparticle (M-A x O y ) is produced by: generating, in an inert gas, an alloy (A-M) nanoparticle, which contains 0.1 at.% to 30 at.% of a noble metal (M), with the balance being a base metal (A) and inevitable impurities, and which has a particle size of 1 nm to 100 nm (preferably 1 nm to 100 nm), to heat the alloy (A-M) nanoparticle and to bring the alloy nanoparticle into contact with a supplied oxidizing gas during transporting the alloy nanoparticle with the inert gas, to oxidize the base metal component (A) in the alloy (A-M) nanoparticle floating in the gases, and to phase separate into the thus-oxidized base metal component (A x O y ) and the noble metal component (M), to thereby obtain a composite nanoparticle (M-A x O y ).

Process for preferentially oxidizing sulfides in gold-bearing refractory ores

A process is provided for recovering gold from refractory sulfide ores. Preferred feed materials have multiple different sulfide mineralogies, with gold being primarily contained within one or more, but not all, of the sulfide mineralogies. Sulfide mineralogies with the highest gold values are preferentially oxidized, while those sulfide mineralogies with relatively little gold remain largely unoxidized. In one embodiment, dissolved arsenic following pressure oxidation is precipitated as ferric arsenate through the control of pH during neutralization. In another embodiment, the oxidized slurry following pressure oxidation is contacted with an oxidizing agent to convert at least a portion of ferrous iron to ferric iron. Following, pressure oxidation, the slurry can be subjected to cyanidation recovery of gold, and liquid from the tailings stream can be recycled upstream of the pressure oxidation step in a substantially untreated form. The process is useful for recovering gold contained as ultra-small masses in sulfide minerals.
