The application of sodium hydrosulfide in minerals
Sodium hydrosulfide Operating Principles in Specific Application Fields
Sodium hydrosulfide Beneficiation Purification Process
As a dedicated regulator for the beneficiation of sphalerite (chemical formula: ZnS):
Elimination of Excess Heavy Metal Interference Before Introduction of Metal Extraction Solution
Recommended dosage range: 3%–13% solution injected into mixing tanks, with a flow rate of 4.5 m³/min for mixing the material stream.
Mechanism of action: HS⁻ preferentially adsorbs on secondary metal particles such as iron and chromium to form a double electric layer, preventing them from attaching to the surfaces of other minerals.
Key benefits: Concentrate sulfur content increased by 12%, while tailings metal residues dropped to within the 0.77‰ standard.
Implementation case: Comparative data from an Anhui smelter shows this method extended the service life of electric zinc removal equipment from 380 hours to 617 hours.
