Advanced Chemical Solutions for Optimized Sulfide Ore Processing
Clariant Mining Solutions delivers advanced flotation reagents that optimize recovery, concentrate grade, and operational efficiency in sulfide ore processing. Our comprehensive portfolio includes customized collectors tailored to specific ore mineralogy, frothers optimized for bubble size and stability, depressants for graphite, pyrite and for copper-moly separation (NaSH replacement), filter aids for concentrates, and acid mist supressants for electrowinning operations.
HOSTAFLOT™ Flotation Collectors
Clariant Mining Solutions flotation collectors are engineered to increase sulfide recovery rates and concentrate grade during sulfide ore processing.The HOSTAFLOT™ flotation collector product line includes:
- HOSTAFLOT™ formulated collectors including dithiophosphates (DTP), thionocarbamates (TC), dithiophosphinates (DTPI), and customized formulations to maximize recovery and grade as the ore changes throughout the life of the mine.
- HOSTAFLOT™ xanthate-replacement collectors as a safer and more sustainable alternative for sulfide ore flotation without compromising recovery. Ready-to-use, non-flammable, water-soluble liquid collectors that eliminate the exposure to hazardous decomposition products like C₂S that can take place during preparation and use of xanthates.
- HOSTAFLOT™ collectors for coarse particle flotation to improve recovery of particles larger than 200µm when trying to increase mill throughput or designing coarse gangue rejection circuits.
FLOTANOL™ Frothers
Clariant Mining Solutions’ frothers optimize sulfide flotation through precise froth stability and bubble control to maximize mineral recovery. They are customized for each operation's specific needs to improve bubble mechanical strength for coarse and fine particle recovery while allowing effective drainage.
Specially formulated FLOTANOL™ frothers for coarse particle flotation improve flotation circuits operating at larger particle sizes.
FLOTICOR™ DP Depressants
Depressants designed to optimize mineral separation in sulfide ore flotation operations.The FLOTICOR™ DP depressant product line includes:
- FLOTICOR™ DP copper depressants to replace NaSH in copper-molybdenum separation, eliminating H₂S exposure while maintaining recovery at lower dosages
- FLOTICOR™ DP pyrite depressants to reduce iron content in copper concentrates
- FLOTICOR™ DP carbon depressants to suppress carbonaceous gangue interference in carbon-containing ores
- FLOTICOR™ DP clay and silicate depressants to minimize interference of talc, biotite, mica, feldspar and other silicates in flotation
Coarse Particle Flotation Reagents
HOSTAFLOT™ collectors and FLOTANOL™ frothers optimized for recovery of particles larger than 200µm.
Clariant Mining Solutions’ coarse particle flotation chemical solutions enable greater energy efficiency, increased throughput, and improved tailings handling. Whether increasing grind size to increase throughput or designing new circuits with coarse gangue rejection, Clariant’s coarse particle flotation reagents help optimize sulfide flotation performance.
FLOTICOR™ FA Filter Aids
Reduce moisture content and optimize filtration rate in filtration of sulfide ore concentrates and tailings.
FLOTICOR™ EW PFAS-free Acid Mist Suppressants
Non-fluorinated suppressants for acid mist in electrowinning and electroplating operations to decrease airborne acid concentration. Clariant’s acid mist suppressants are completely compatible with the electrolyte solutions and preserve cathode quality.
Flotation Solutions for Frequently Occurring Sulfide Minerals
Clariant Mining Solutions offers an extensive portfolio of high-performance flotation reagents specifically designed for the following sulfide minerals:
Los colectores HOSTAFLOT™ están formulados para lograr la mejor recuperación y grado posibles en sus operaciones de flotación de cobre, independientemente de que procesen cobre de mineralización primaria, secundaria o de óxido. Nuestros espumantes FLOTANOL™ se producen a la medida de sus necesidades para ayudarlo a obtener la espuma adecuada para maximizar la recuperación de materiales gruesos o finos, y nuestros aditivos FLOTICOR™ pueden ayudarlo a trabajar con minerales difíciles con pulpas de alta viscosidad o contaminantes indeseables.
Los depresores de sulfuros FLOTICOR™ DP son reemplazos eficientes del NaSH para deprimir el cobre en la flotación de molibdeno en concentrados de cobre-molibdeno.
Los depresores de pirita FLOTINOR™ DP añadidos a la alimentación de la flotación rougher, al concentrado de la flotación rougher o incluso al concentrado del primer limpiador en un circuito con múltiples etapas de limpieza, reducen el contenido de hierro en el concentrado al deprimir minerales de sulfuro de hierro como la pirita.
Los colectores HOSTAFLOT™ están formulados para obtener la mejor recuperación posible y el grado más elevado en el concentrado a granel de cobre-molibdeno. Existen productos con bajo contenido de aceites y compuestos aromáticos que cumplen con requisitos sanitarios, ocupacionales y ambientales más estrictos.
Los depresores de sulfuros FLOTICOR™ DP son productos de reemplazo del NaSH más seguros para la separación Cu-Mo que eliminan el riesgo de exposición al H2S en todas las condiciones del proceso, mantienen la recuperación y ley del molibdeno, y generalmente pueden usarse en dosis más bajas que el NaSH.
Los colectores HOSTAFLOT™ de Clariant Mining Solutions están formulados para lograr el mejor grado y recuperación posibles para sus necesidades mineras únicas. Nuestros colectores son más selectivos contra la cromita y el talco, y proporcionan un aumento en la recuperación de los minerales del grupo platino (PGM) y un concentrado con un menor contenido de cromo y talco.
Los colectores HOSTAFLOT™ están formulados para lograr la mejor recuperación posible y selectividad cuando fuese necesario. Nuestras soluciones incluyen la flotación de minerales que contienen plomo, zinc, cobre, níquel y cobalto. Nuestros espumantes FLOTANOL™ se producen a la medida de sus necesidades para ayudarlo a obtener la espuma adecuada para maximizar la recuperación de materiales gruesos o finos.
Los colectores HOSTAFLOT™ están formulados para lograr la mejor recuperación posible y cumplir con las especificaciones del concentrado. Nuestras soluciones pueden ayudarlo a optimizar su plata y oro asociados a la flotación de sulfuros. Nuestros espumantes FLOTANOL™ mejoran la resistencia mecánica de las burbujas, lo que aumenta la recuperación de las partículas gruesas y permite un buen drenaje de minerales de la ganga.
