✅ Z-6 (Sodium Isobutyl Dithiocarbamate) 

Z-6 (Sodium Isobutyl Dithiocarbamate) is a high-selectivity, medium-to-high strength dithiocarbamate flotation collector used in the beneficiation of copper, gold, silver, and activated zinc sulfide ores.
Positioned between Z200 and Z-5 in collecting intensity, Z-6 provides excellent selectivity, improved pyrite rejection, and strong adsorption on target sulfide minerals, making it highly effective in both rougher and cleaner flotation circuits.

Because of its balanced collecting strength and superior selectivity, Z-6 is widely used in copper–gold deposits, gold–silver flotation, and complex sulfide ores requiring tight control over iron sulfide flotation.

Compared with Z200/ZDTC, Z-6 offers stronger adsorption and improved kinetics; compared with Z-5, it offers higher selectivity with less over-collection, making Z-6 ideal for operations targeting higher-grade concentrates.

Engineered for modern flotation plants, Z-6 delivers:
• Strong adsorption on chalcopyrite, bornite, chalcocite, and precious-metal sulfides
• Improved selectivity against pyrite, pyrrhotite, and arsenopyrite
• Superior recovery of fine and refractory gold-bearing sulfides
• Excellent performance in copper–gold and copper–zinc flotation circuits
• Cleaner concentrates with reduced sulfur and penalty elements
• Stable performance across wide pH and pulp chemistry ranges
• Synergistic action when used with xanthates, dithiophosphates, DTP-type collectors

Z-6 is especially effective in:
• copper–gold (Cu–Au) flotation
• gold and gold–silver flotation in pyritic ores
• activated sphalerite (CuSO₄-treated zinc ores)
• complex Cu/Pb/Zn differential flotation
• cleaner flotation stages requiring high-grade concentrates
• fine-grained or partially oxidized sulfide ores

Z&Z supplies Z-6 with consistent active content, strict quality control, and export-grade packaging for mining companies and flotation reagent distributors worldwide.

Packaging:
• 25 kg bags
• 50 kg drums
• Liquid formulations available in IBCs（如客户需要）
