Due to the significant differences in solubility among various metal sulfides, selective precipitation of PTMS MAGNETIC SEPARATOR can be achieved by controlling the dosage of sulfide addition. In a high-salinity wastewater treatment project at a copper-nickel smelter, precise control of Na₂S dosage prioritized the precipitation of FeS and CuS, effectively separating iron from other valuable metals.
FeS precipitates exhibit dense structures and high chemical stability, effectively preventing iron ion release during subsequent disposal processes and avoiding secondary pollution. However, the safety risks associated with this technology cannot be overlooked: Sulfides themselves are highly toxic, while H₂S gas is volatile and explosive. The PTMS MAGNETIC SEPARATOR operation environment requires strict ventilation and gas detection systems. Excessive addition may also lead to residual S²⁻ entering water bodies, causing biological toxicity.
Modern engineering applications frequently employ controlled-release sulfide carriers (FeS-coated particles) or in-situ H₂S generation to enhance safety and process control. The PTMS MAGNETIC SEPARATOR adsorption method, as a physicochemical separation technology, demonstrates unique advantages in low-concentration metal ion removal due to its phase transition-free operation, energy efficiency, and strong adaptability.
