Sodium sulphide These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).
This would interfere with the reduction of the silver sulphide, as the large amount of hydrogen given off prevented the actual contact necessary between the sulphide and the aluminum. The desulphurized precipitate was collected in a filter press, washed free of sodium sulphide, and delivered to the refinery.
Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the in 191520 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in ...
Sodium hydrosulfide (NaSH) is a chemical reagent with numerous applications within predominately three (3) industries: Kraft Paper Milling. In Kraft, pulping sulfidity is controlled through the use of reduction furnaces which reduce sodium sulfate plus caustic soda to sodium sulfide.
It can be used in sulfur dye, reductant of dye intermediate, mordant, flotation agent of ore, depilation agent of leather, paper cooking agent. Moreover, it is widely used in textile, pigment and rubber industry, or used in the production of sodium thiosulfate, sodium polysulfide and sodium hydrosulphide.
Jul 22, 2019· Sodium Sulphide Use in Mining Industry: One of other main sodium sulfuret uses is in the process of ore flotation in mining companies. They use Na2S ( sulfur sodium) ( sodium sulfur ) as an agent in the ore flotation process of Zinc, copper, iron, and other metal ores.
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 membranegrade caustic soda to produce the purest and most consistent product on the market.
Sodium hydrosulfide is the chemical compound with the formula NS. This compound is the product of the halfneutralization of hydrogen sulfide (H 2 S) with sodium hydroxide. NS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution.
Not all sulfide mines will result in the severity of harm experienced at Torch Lake. Moreover, some of sulfide mining''s ecological threats can be mitigated or avoided alto gether. Nevertheless, the decision to allow sulfide mining inevitably is a decision to permit some ecological harm.

Sodium hydroxide + sodium sulphide These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).
Sodium Sulphide (Na2S) /Sodium Hydrosulphide (NS): Commonly used prior to collector addition for the activation of Cu, Pb, and Zn minerals. The choice of whether to use Na2S or NS depends on the pH required in flotation, as Na2S is more alkaline and also, whichever works best (test to verify).

Sulfide reagents used to cause precipitation of contaminants include iron sulfide (FeS), sodium hydrosulfide (NS) (WellingtonOro Water Treatment Plant), sodium sulfide (Na 2 S), calcium sulfide (CaS), and biogenic sulfide generated in situ by
Sodium Hydrosulphide (NS) flakes, liquid, solid. Mining: Flotation agent. NS 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.
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan, Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.
Sodium sulfide is used in many industries; for example, the pulp and paper industry and in leather processing to remove hair from hides. Sodium sulfide may be used in the making of colors and dyes. Sodium sulfide can also be used in the manufacture of other chemicals, metals or in mining
