Selling High Quality Sodium Hydro Sulphide (Nash) to Leading Textile Dye Manufacturers. Sodium Hydrosulphide is used in paper manufacture as a makeup chemical for sulfur used in the Kraft process, as a flotation agent in copper mining where it is used to activate oxide mineral species, and in the leather industry for the removal of hair from hides.
Nouryon is the global producer of sodium hydrosulfide (NaSH), which is available in different aqueous solutions (including 30%, 40%, 42%, 45% and 60%). We start with elemental sulfur and membrane grade caustic soda to produce the purest and most consistent product on the market.
Abstract. This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na 2 S183;9H 2 O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10 1 10 2 mol/L.

Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S183;9H 2 O.Both are colorless water soluble salts that give strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.Some commercial samples are specified as Na 2 S183;xH 2 O, where a weight percentage of Na 2 S is specified.
Copper monosulfide is a chemical compound of copper and sulfur. It occurs in nature as the dark indigo blue mineral covellite. It is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H 2 S, is bubbled through solutions of Cu(II) salts.
Flotation of the carbonate, oxide and silicate minerals of copper (malachite, azurite, chrysocolla) has been the subject of much research in recent years, but few effective solutions to this problem have been found. With decreasing reserves of sulfide minerals, the economic recovery of these oxides appears to be an important source of copper for the future.
A method of depressing copper sulfides and iron sulfides in a molybdenite floatation recovery process uses alkaline or alkaline earth potysulftdes at high concentrate pH. The method of enriching molybdenite content from a slurry having molybdenite and at least one of iron sulfides and copper sulfides can include the steps of adding an effective amount of a depressing reagent selected from one
A wide variety of copper sulfide options are available to you, such as industrial grade, electron grade, and agriculture grade. There are 619 copper sulfide suppliers, mainly located in Asia. The top supplying countries or regions are China, Pakistan, and Taiwan, China, which supply 98%, 1%, and 1% of copper sulfide respectively.

Jul 17, 20060183;32;Sodium sulfide very efficiently removes copper from protected amino acidcopper complexes. The copper in the amino acid complex was reduced to insoluble cuprous sulfide and the free amino acid was released in pure form. This method is very convenient and rapid, requiring only 510 min and 0.550.75 equiv of sodium sulfide.
Sodium hydro sulfide is the chemical compound with the formula NaHS. This compound is the product of the half neutralization of hydrogen sulfide with sodium Hydroxide NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, and more often as an aqueous solution.
