Benefits of using sodium hydrosulfide in mineral processing
Improved recovery: With sodium hydrosulphide, the efficiency of the flotation process is significantly improved, meaning a higher percentage of the target mineral is recovered, optimizing the output and profitability of the mining operation. 1.For example, in some copper ore beneficiation, the co...Read more -
The key role of sodium hydrosulfide in ore flotation
Flotation is a method of separating and enriching ores by changing the hydrophobicity or hydrophilicity of the ore surface. The principle is that hydrophobic particles will float on bubbles for easy scraping, while hydrophilic particles will sink. Sodium hydrosulfide, as a flotation reagent, can ...Read more -
