Fatty Amine Collector (Ether Amine Type)
CAS Number: 61790-33-8
Fatty amine ether amine collectors are cationic collectors primarily used in reverse flotation of silica from iron ore and phosphate concentration circuits. They selectively float quartz, feldspar, and aluminosilicate gangue minerals while leaving iron oxide or phosphate minerals in the flotation cell. These reagents are supplied as liquid concentrates and are typically used in conjunction with starch depressants to achieve high-grade iron ore concentrates.

Applications
- Reverse flotation of silica from iron ore concentrates
- Phosphate ore flotation (silicate rejection)
- Potash ore (sylvinite) flotation
- Feldspar and quartz separation circuits
- Bauxite desiliconization by flotation
Key Features
- High selectivity for silicate gangue over iron and phosphate minerals
- Effective in both cold and warm water flotation conditions
- Works synergistically with starch and dextrin depressants
- Liquid form enables easy dilution and dosing
