A breakthrough in processing challenging medium-low grade collophosphate ore—high in aluminum, complex in composition, and costly to upgrade.
Our new Pre-Concentration & Double Reverse Flotation Process integrates photometric and dense-media separation with reverse flotation to efficiently remove aluminum- and magnesium-containing gangue, without desliming. The technology features a specially developed series of reverse flotation collectors adaptable to phosphate ores from different regions, overcoming long-standing difficulties in froth mobility, separation efficiency, and water recycling.
Key Performance:
1. ~35% reduction in processing cost
2. Recovery of P₂O₅: 80–90%
3. Ambient temperature & weak alkaline-acidic flotation
4. First-of-its-kind industrial system for collophosphate ore
A step forward in making more phosphorus resources viable, sustainably and economical.
