Minimizing use of hazardous chemicals in mining operations
Improving Safety in Mining Operations with Less Hazardous Chemicals
Mining companies are seeking to improve the working environment for their employees and to reduce their environmental impact by using chemicals that are safer to store and use and eliminate workplace emissions and by eliminating the use of persistent chemicals.
Clariant's xanthate-replacement collectors, copper depressants that replace NaSH and acid mist supressants that are free of PFAS are safer and less toxic, contributing to our customers’ goal of using less hazardous chemicals in their mining operations.
Xanthate-replacement collectors: improving safety in sulfide ore flotation
HOSTAFLOT™ Xanthate-Replacement Collectors:
Clariant Mining Solutions offers HOSTAFLOT™ xanthate-replacement collectors, enabling mining operators to use safer alternatives to xanthate collectors without compromising performance in the flotation of copper ores, polymetallic ores and gold associated to sulfides.
HOSTAFLOT™ xanthate-replacement collectors are ready-to-use liquid collectors that have comparable flotation performance and the following benefits:
- Enhanced safety: ready-to-use, water-soluble, non-flammable liquid formulations that eliminate C2S exposure during preparation and use.
- Operational efficiency: simplified inventory management and elimination of dilution processes to reduce operational complexity.
- Environmental responsibility: no packaging waste with chemical residues to lower the environmental impact of mining operations.
- Versatile application: functions as primary or secondary collector depending on operational needs.
NaSH-replacement depressants: safer and more efficient molybdenum flotation
FLOTICOR™ DP Copper Depressants for NaSH Replacement:
Clariant’s FLOTICOR™ DP copper depressants for NaSH replacement completely replace sodium hydrosulfide (NaSH) in copper-molybdenum flotation.
FLOTICOR™ DP copper depressants for NaSH replacement effectively depress iron and copper sulfides while delivering target molybdenum grade and recovery at significantly lower dosages than NaSH.
FLOTICOR™ DP copper depressants for NaSH replacement eliminate H₂S exposure risks across all process conditions, removing the need for scrubbers while maintaining optimal molybdenum recovery performance. Our water-soluble, odorless formulations work effectively across a wide pH range and fully integrate with existing plant equipment and flowsheets.
Unlike competing alternatives that only partially replace NaSH, FLOTICOR™ DP copper depressants for NaSH replacement enable complete elimination of NaSH from beneficiation plants.
PFAS-free acid mist suppressants: safer electrowinning operations
FLOTICOR™ EW Acid Mist Suppressants:
Clariant’s FLOTICOR™ EW acid mist suppressants effectively control acid mist in electrowinning and electroplating processes without using perfluoroalkyl and polyfluoroalkyl substances (PFAS).
FLOTICOR™ EW acid mist suppressants deliver performance equivalent to PFAS-based suppressants while maintaining complete compatibility with electrowinning electrolytes and preserving cathode quality.
