Water Scarce Area Mineral Dry Sorting Solution

The Dry Separation Solution for Minerals in Water-Scarce Areas is an innovative mineral processing system designed for arid and water-scarce environments. It adopts the core process of "more crushing and less grinding, dry separation", which combines high-efficiency crushing with multi-stage dry separation to effectively separate iron ore and other minerals without the need for water washing. This solution is especially suitable for arid and water-scarce areas, environmentally controlled areas and resource utilization of scattered ore bodies.

Core Technology

Dry sorting process flow

Generalized process flow:
Raw ore → coarse crushing (jaw crusher) → medium crushing (cone crusher) → fine crushing (impact crusher) → ultra-fine crushing (roller mill) → multi-stage dry sorting → concentrate collection → tailings dry discharge

Main System Composition

Crushing system:

• Jaw crusher: coarse crushing to 100-200mm

• Cone crusher: medium crushing to 30-50mm

• Impact crusher: fine crushing to 10-20mm

• Roller mill: ultra-fine crushing to 0-5mm

Separation system:

• Dry magnetic separator: processing magnetite, vanadium and titanium magnetite, etc.

• Wind Sorting Machine: Sorting coal, quartz and other minerals.

• Electrostatic separator: separating minerals with different electrical conductivity such as rare earths, zircon, etc.

• Compound force field separator: processing complex symbiotic minerals

Environmental protection and energy saving index

• Water consumption: zero water consumption

• Electricity consumption: 20%-30% lower than the wet method

• Dust emission: <10mg/m³.

• Tailings disposal: dry stockpiling, no tailing ponds

Advantageous features of the program

Environmental Advantages

• Zero water process: completely dry sorting, no wastewater discharge

• No tailings storage: dry storage of tailings, eliminating environmental risks.

• Dust control: the whole process is closed to remove dust, and meets the emission standards.

• Eco-friendly: Reduce water resource extraction, protect the ecological environment.

Economic Advantages

• Investment saving: no need for dewatering, tailings storage and other facilities, reducing investment by 30-40%.

• Low operating costs: 25%-35% reduction in the cost of tons of ore.

• Reduced energy consumption: more breakage and less grinding process, power consumption reduced by 20%-30%.

Application Scenario

Geographic environment

• Arid and water-scarce areas (Northwest, Inner Mongolia, Australia, Middle East, etc.)

• Cold regions (to avoid the impact of icing)

• Remote and decentralized mining areas (reduce infrastructure investment)
