Oct 22, 2012· A New Application For Flotation Of Oxidized Copper Ore – Mining . In another study, sulphidising flotation of oxide copper-cobalt ores, using sodium hydrosulphide as the sulphidising agent, has been practiced in Katanga, Democratic . Flotation of mixed copper .
Sodium Hydrosulfide. Sodium hydrosulfide is used more as a common commercial form than sodium sulfide. It is prepared by absorption of hydrogen sulfide in sodium hydroxide. It is shipped as a 45% solution with a specific gravity of 1.303 and a pH of 10.4. The viscosity is 7 centipoise. The solution tends to crystallize below 62°F (17°C).
Sodium Hydrosulfite is Generally Regarded As Safe for use with Textiles and Textile Fibers for producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food [21 CFR 177.2800(d)(1)].

Patch clamp studies of neuroblastoma cells have shown that in the presence of sodium hydrogen sulfide, the in vitro precursor of hydrogen sulfide, addition of the sulfonated amino acids, taurine or cysteic acid resulted in reversible abolition of the inward of the sodium currents. This effect could also be demonstrated by preincubating cells for 3-20 min within 5-10 mM sodium hydrosulfide ...

Sodium Hydrosulphide (NaHS) flakes, liquid, solid. Mining: Flotation agent. NaHS is also used as a substitute for sodium sulphide for the sulphidization of copper, oxides of copper, lead or zinc making them amenable to collector attack. Commonly used prior to collector addition for the activation of Cu, Pb, and Zn minerals.
In cyanidation, zinc (the Merrill-Crowe Process) is practically the universal precipitant for precious metals dissolved in cyanide solutions although for specific reasons aluminium and charcoal have been used. During the reactions involved in precipitation, the greater part of the zinc dissolves in the cyanide solution and forms various cyanogen complexes such as sodium or calcium zinc cyanide ...

Sodium hydrosulfide hydrate is a hydrated inorganic salt of sodium. It participates in the synthesis of (E)-2-cyano-2-(thiazolidin-2-ylidene)ethanethioamide. Application It may be used as a sulfur nucleophile to induce the C-S bond formation in α,β-dichloro vinyl ketones to form 5- to 8-membered cyclic thioethers.
