Product Details
Sodium Metabisulfite (SMBS), offered by Y&X Beijing Technology Co., Ltd., is a widely used flotation depressant, particularly effective in sulfide mineral processing. It modifies the surface chemistry of target minerals, reducing their floatability and supporting more selective separation in complex ore systems.
Product Features
-
Depresses Sulfide and Oxidized Minerals
Forms a hydrophilic adsorption film on mineral surfaces, preventing interaction with collectors. -
Versatile Flotation Modifier
Can be used alone or in combination with other reagents to enhance separation efficiency in polymetallic or high-carbon ore systems. -
Flexible Dosage
Dosage depends on ore type and plant conditions; recommended to follow on-site reagent guidelines.

Environmental Notes
-
Most of the reagent is consumed during flotation or in subsequent processing steps
-
Remaining traces enter tailings—avoid direct release into water systems
