Product Details
D481, developed by Y&X Beijing Technology Co., Ltd., is a high-efficiency flotation depressant specifically designed to suppress fine graphite, cryptocrystalline carbon, and other carbon-containing gangue minerals in non-ferrous metal ores. It enhances concentrate grade and recovery by reducing carbon interference in flotation circuits.
Key Features
-
Suppresses Carbon and Graphite Gangue
Effectively prevents carbon-containing materials from entering the concentrate, ensuring a cleaner separation and better flotation selectivity. -
Improves Recovery and Concentrate Grade
Reduces collector loss and enhances the efficiency of flotation reagents by eliminating carbon competition. -
Ideal for Non-Ferrous Ores
Suitable for copper, lead-zinc, and gold ores containing fine or microcrystalline graphite. -
Simple to Use
Easily prepared as a 2% solution and added directly to the flotation process.
