An oxide superconducting wire includes an oriented metal substrate, an intermediate layer formed on the oriented metal substrate, and an oxide superconducting layer formed on the intermediate layer. The oriented metal substrate has an in-plane orientation of 7 or less. The intermediate layer is formed of a single layer.

This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.

The system and method for remediation of oil-contaminated sand provides for washing and separation of sand from oil and oil-based contamination. The system includes a feed hopper for receiving a volume of oil-contaminated sand in communication with a cleaning tank for receiving the volume of oil-contaminated sand therefrom. A mechanical stirrer mixes the volume of oil-contaminated sand with a surfactant solution in the cleaning tank. An ultrasonicator ultrasonicates the volume of oil-contaminated sand and the surfactant solution in the cleaning tank to create a mixture of washed sand and oily wastewater. A collection tank then receives the mixture. A band filter covers an open upper end of the collection tank, such that the mixture of washed sand and oily wastewater is filtered to separate out the washed sand, which may then be collected. The separated oily wastewater is then collected in the collection tank.

Process for producing a suspension by precipitation of a solid from a solution, wherein at least two solutions of salts are combined with one another in a stirred vessel so as to form a sparingly soluble solid, where portions of suspension are taken off continuously or discontinuously, the portions taken off in this way are processed in a combination of two separation apparatuses, where gas is separated off in a first separation apparatus which is selected from liquid-gaseous separation apparatuses, and mother liquor is separated off from precipitated sparingly soluble solid in a second separation apparatus selected from solid-liquid separation apparatuses, and the mother liquor is taken off, and the solid which has been separated off or enriched in this way is returned to the reaction mixture.
