ZDTC (Diethyl / Dibutyl Dithiocarbamate) is a high-selectivity flotation collector offering strong adsorption and superior pyrite rejection for copper, gold, silver, and activated zinc ores.
ZDTC (Diethyl / Dibutyl Dithiocarbamate) is a highly selective dithiocarbamate flotation collector widely used for the recovery of copper, gold, silver, and activated zinc sulfides.
As a stronger and more versatile alternative to standard Z200, ZDTC offers greater adsorption strength, improved selectivity, and enhanced metallurgical performance in complex and challenging ore bodies.
ZDTC is typically available in Diethyl and Dibutyl formulations, allowing concentrators to select the most suitable collector strength and selectivity for their ore type.
Both formulations exhibit strong chemisorption, excellent pyrite rejection, and outstanding performance in cleaner flotation, making ZDTC one of the most reliable collectors for high-grade, low-sulfur concentrates.
Engineered for high-performance sulfide flotation, ZDTC delivers:
• Stronger adsorption compared to Z200 and Z200A
• High selectivity for chalcopyrite, bornite, chalcocite, and fine gold-associated sulfides
• Excellent pyrite and pyrrhotite rejection
• Superior performance in refractory or finely disseminated gold ores
• Improved cleaner-stage flotation and concentrate grade
• Enhanced performance in copper–zinc and copper–gold separation
• Stable activity across broad pH ranges
• Excellent synergy with xanthates, dithiophosphates, and thionocarbamates
ZDTC is especially effective in:
• copper–gold ore bodies (Cu–Au)
• gold and gold–silver flotation with high pyrite levels
• activated zinc flotation (CuSO₄-treated sphalerite)
• copper–zinc differential flotation
• fine-grained, low-grade, or refractory sulfide ores
• cleaner flotation circuits requiring high-grade concentrates
• operations where xanthates cause excessive pyrite collection
