Mineral processing technology determines concentrate grade, metal recovery rate, equipment investment and production cost. Improper process matching will lead to low output, high energy consumption and poor beneficiation effect.

1. Select Process According to Ore Properties

Magnetic Metal Ore – Magnetic Separation

Suitable for magnetite, hematite, manganese ore, titanium ore and chromium ore. Magnetic separation features large processing capacity, high automation, no chemical pollution and low maintenance cost, ideal for large-scale continuous mining production.

Non-ferrous & Fine-grain Non-metallic Ore – Flotation

Applicable to copper ore, lead-zinc ore, molybdenum, fluorite, graphite and phosphate ore. Flotation accurately separates fine embedded minerals through reagent adjustment, effectively improving concentrate grade and recovery rate.

High-density Precious Metal Ore – Gravity Separation

Perfect for gold ore, tungsten ore, tin ore, placer and coal. Gravity separation requires no chemical agents, with low investment and environmental protection advantages, suitable for small and medium-sized mines.

Low-grade Refractory Ore – Chemical Processing

Chemical leaching processes (CIL, CIP) are adopted for low-grade gold ore and oxidized ore to extract valuable metals and improve resource utilization.

2. Select Process According to Mineral Embedding Particle Size

Coarse-grain embedded minerals are suitable for simple gravity separation and magnetic separation with low energy consumption. Fine and micro-grain embedded minerals require flotation or chemical processing with precise grinding and classification procedures to achieve full mineral dissociation.

3. Select Process According to Production Capacity

Small and temporary mining projects prefer simple gravity separation and dry magnetic separation for fast commissioning and low cost. Large standardized mineral processing plants adopt combined magnetic separation and flotation processes to meet high-yield and high-quality production requirements.

4. Select Process According to Environmental Protection and Cost

For strict environmental protection areas, choose pollution-free processes such as gravity separation and dry magnetic separation. For high-grade concentrate requirements, flotation or combined processes are recommended. For cost-sensitive projects, simple physical separation processes are the best choice.

Conclusion

The principle of mineral process selection is matching technologies with ore characteristics and production demands. Reasonable selection and combined application of gravity separation, magnetic separation, flotation and chemical processing can maximize beneficiation efficiency, reduce operating costs and realize sustainable mining production.
