Dongou MF is pleased to announce its participation in MiningWorld Summit 2026, taking place from November 16–18, 2026, at the Hyatt Regency Petrovsky Park in Moscow. We invite industry professionals to visit our booth to explore our latest innovations in hydrometallurgy filtration.
About Dongou Microfiltration
Founded in 1986, Dongou specializes in R&D, equipment manufacturing, and engineering applications for precision liquid-solid separation. We master core technologies in polymer-sintered microfiltration membranes, tubular microfiltration membranes, and complete filtration systems. Our solutions serve a wide range of industries, including non-ferrous hydrometallurgy, chemicals, new energy, biopharma, water treatment, and Zero Liquid Discharge (ZLD).
As a National “Little Giant” Enterprise and a Hidden Champion of Zhejiang Province, Dongou is also the Editor-in-Chief of China’s National Standard for Polymer-Sintered Microfiltration Membrane Elements (GB/T 47900-2026).
Core Technologies & Equipment
- Tubular Microfiltration Technology: High flux, high retention, and corrosion-resistant, ideal for complex liquid conditions.
- Precision Microporous Filters: Designed for solution residue removal, clarification, and mother liquor recovery.
- Integrated Filtration-Washing-Dewatering Unit: Perfect for solid-liquid separation of ultra-fine powders, metal salts, and crystalline products.
- Modular Skid Systems: Supporting new line integration, retrofits, and fully automated continuous operation.
- Online Cleaning (CIP): Minimizes downtime and reduces maintenance costs.
Key Applications in Non-Ferrous Hydrometallurgy
| Process Stage | Process Stream | Core Value |
| Metal Salt Washing | Metal salts, crystalline powders, mother liquor | Improves purity and yield |
| Solution Clarification | Leach liquors, wash water, circulating liquids | Reduces suspended solids, stabilizes downstream |
| Post-Extraction De-oiling | Extractants, oil-bearing liquids | Removes trace organics and emulsions |
| Pre-Crystallization Polishing | Crystallization feed, concentrates | Optimizes crystal size and quality |
| Wastewater Reuse & ZLD | Wash water, process water, circulating water | Reduces water footprint and discharge |
