Surface properties of copper-sulfide minerals with sodium

Sep 01, 2020· Sodium hydrosulfide, NaHS, is a flotation reagent for several copper minerals. For example, NaHS is used commonly in Cu–Mo flotation as a depressant for chalcopyrite ( WillsB, 2016, Bulatovic, 2007, Ansar and Pawlik, 2007 ).Biogenic Sulphide Reagent in Hydrometallurgy,Uses under consideration by a number of mining companies include: (1) replacement of sodium hydrosulphide . in the SART process for cyanide regeneration and copper recovery in the processing of gold-copper ores, and (2) replacement of sodium hydrosulphide for use in the separation of copper and molybdenum in flotation. Biogenic

Sodium hydrosulfide NaHS PubChem

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 hydrosulfideSodium Hydrosulfide an overview ScienceDirect Topics,Copper (I)-catalyzed tandem thiolation and 6- exo -dig heterocyclization of 1- (2-chloro-3,3,3-trifluoroprop-1-enyl)-2-ethynylbenzenes with sodium hydrosulfide affords 1 H -isothiochromenes in a highly regio- and stereoselective way with moderate to excellent yields ( Scheme 83) 〈12S966〉.

Sodium Hydrosulfide Handbook

Sodium hydrosulfide, NaHS, is a highly alkaline liquid with a pH range of 11.5 to 12.5. The liquid solution is typically yellow to dark green in color and has a strong hydrogen sulfide (rotten egg) odor. Solutions of NaHS are considered stable in normal transportation. Solutions range from 20 to 45% strength by weight and weigh 9.6 toSodium hydrosulfide Wikipedia,Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H2S) with sodium hydroxide. NaHS and sodium sulfide are used industrially, often for similar purposes. Solid NaHS is colorless. The solid has an odor H2S owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide(Na2S), wh
