HB-421
Description
Used as an effective flotation collector for copper sulfide, gold minerals. It exhibits strong selectivity for copper in the flotation of copper sulfide minerals. The collector could improve the recovery of copper and concentrate grade. It is particularly effective in the flotation of argillious gold ores and fine-grained gold ores, and it helps to improve the recovery of gold. It could also be used as an effective substitute for xanthates and dithiophosphates, it could help to improve flotation process and reduce dosage of frother.
Packing
200kg net plastic drum or 1000kg net IBC Drum
Storage: Store in a cool, dry, ventilated warehouse.
FAQ
Q1: What are the appearance and physical-chemical specifications of HB-421?
A: It is yellow to brown transparent liquid, with minimum 95% active ingredient. Its specific gravity ranges from 1.0 to 1.05 at 20℃ and the pH value is around 9.
Q2: What kind of mineral reagent is HB-421? What ores is it mainly applicable to?
A: HB-421 is a new-type flotation collector specially for copper sulfide and gold ores, which can replace xanthates and dithiophosphates. It is mainly used for flotation of copper sulfide ore, argillaceous gold ore and fine-grained gold ore.
Q3: What advantages does HB-421 have compared with xanthates and dithiophosphates?
A: 1. It features strong selectivity for copper to improve copper concentrate grade and copper recovery rate;
2. It delivers outstanding flotation performance for argillaceous and fine-grained gold ores to boost gold recovery;
3. It helps cut the dosage of frother, optimize the whole flotation process and lower comprehensive reagent cost.
Q4: Under what ore conditions is HB-421 preferentially recommended?
A: It is preferentially applied to raw copper sulfide ore, gold-associated copper ore, high-argillaceous gold ore and fine disseminated gold ore. It can directly replace xanthates and dithiophosphates in existing flotation processes for trial application.
Q5: Why can the dosage of frother be reduced when using HB-421?
A: HB-421 has auxiliary frothing property with dual functions of collection and mild frothing, thus the matching frother dosage can be reduced as required.
Q6: What are the regular packaging specifications?
A: Standard packages are 200kg net plastic drum and 1000kg net IBC tank, customized packaging is available based on clients’ requirements.
Q7: What are the requirements for product storage?
A: Store the product in cool, dry and well-ventilated warehouse, keep away from direct sunlight and high temperature.
