Red mud processing technological process.
1. Preparation Stage: Loading and Self-Grinding
Loading Unit: Red mud with up to 5% moisture is continuously fed into the loading unit.
MSS-IR-1 and MSS-IR-2 Operation: The red mud undergoes sequential processing in high-speed rotary dry self-grinding mills (MSS-IR-1 and MSS-IR-2). These mills selectively disintegrating minerals and achieving particle sizes from 1mm to 0.05mm.
Cyclone Removal: Dusty particles are efficiently removed using cyclones.
2. Intermediate Processing: Refinement and Separation
Dry Magnetic Enrichment Separator Operation: The prepared material moves to the Dry Magnetic Enrichment Separator, where innovative "know-how" construction ensures efficient separation. Non-magnetic particle capture during collision flows is eliminated. The separator operates in magnetic, centrifugal, and gravitational fields, creating distinct end products, including iron ore and aluminum concentrate.
Aerosol Separators: Particles from earlier stages undergo further refinement using Aerosol Separators. Pneumatic sorting in a gravitational field contributes to efficient particle separation, resulting in multiple end products based on particle characteristics.
3. Final Processing: Aerosol Separation and Product Creation
Aerosol Separators Operation: The refined particles, now in the form of distinct fractions, are directed through Aerosol Separators. Pneumatic sorting and gravitational forces ensure precise separation based on density, weight, form, and size.
Creation of End Products: The final stage yields multiple end products, including a magnetic fraction (iron ore), non-magnetic fractions (aluminum concentrate), and a dry, dispersed fine material. Each product is meticulously sorted and processed, contributing to resource recovery.
