RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., 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/sulphide, sodium hydrogensulfide/sulphide can be widely used in mining, leather, paper pulp, water treatment and other industries. Rubber auxiliaries are mainly used in tire manufacturing, rubber pipes, rubber shoes, cables and other industrial rubber products.
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 U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in ...
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.
Mining Action Group The Mining Action Group is a volunteer, grassroots effort to defend the clean water and wild places of Michigan's Upper Peninsula from the dangers of sulfide mining – previously known as Save the Wild U.P.
Solvay is the established market leader worldwide for high grade sodium sulphide (yellow qualities) Sodium Sulphide. Sodium Sulphide is applied in the leather industry, waste water treatment, soil remediation, the mining industry and pulp paper and amongst others.
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.
Sulfide reagents used to cause precipitation of contaminants include iron sulfide (FeS), sodium hydrosulfide (NaHS) (Wellington-Oro Water Treatment Plant), sodium sulfide (Na 2 S), calcium sulfide (CaS), and biogenic sulfide generated in situ by
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.

Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution.
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.
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.
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.
