Applications:
Mining Flotation:
- SDMDTC enhances the separation of valuable minerals from waste rock during froth flotation. It forms complexes with metal ions, aiding the selective flotation of certain ores.
Fly Ash Treatment:
- SDMDTC immobilizes heavy metals in fly ash from coal combustion, reducing their environmental impact. This makes fly ash safer for use in cement production or as a soil amendment.
Heavy Metal Treatment:
- Its chelating properties make SDMDTC ideal for removing heavy metals from industrial wastewater and contaminated soils, facilitating environmental remediation.
- Cobalt Removal in Zinc Smelting (Hydrometallurgy):
- SDMDTC selectively extracts cobalt during zinc purification in hydrometallurgy. This process ensures cobalt impurities are removed, meeting zinc product purity standards and allowing cobalt recovery.
- The selective complexation of cobalt by SDMDTC enables efficient separation from zinc, aiding in the purification process and cobalt recovery.
Agricultural Soil Treatment:
- SDMDTC remediates soils contaminated with heavy metals by forming complexes, reducing bioavailability and mobility of the metals.
Industrial Wastewater Treatment:
- Used in industrial settings to treat wastewater containing heavy metals, helping to meet regulatory discharge standards.
Safety Information:
- Always wear appropriate personal protective equipment (PPE) when handling SDMDTC.
- Avoid inhalation, ingestion, and skin contact. Ensure usage in a well-ventilated area.
Storage Conditions:
- Store in a cool, dry place, away from heat and direct sunlight. Ensure the area is well-ventilated to maintain optimal conditions.
- Keep the container tightly sealed to maintain product integrity and prevent contamination or moisture ingress.
