3 stage crushing to reduce ore size below 12 mm

Flotation circuit:

1 stage rougher flotation
2 stage cleaner flotation
2 stage scavenger flotation
Hydrocyclones used for pre-concentration and desliming to enhance flotation efficiency

Concentrate dewatering:

Hydrocyclone-assisted grinding classification:

2 stage ball mill grinding in closed circuit with hydrocyclones to achieve target particle size of 74 μm (D85)
Hydrocyclones ensure efficient classification and improve grinding circuit stability

Tailing handling: Tailings pumped to tailing pond after thickening

Key Features Highlighting Hydrocyclone Efficiency:

Hydrocyclones in grinding circuit reduce over-grinding and improve energy efficiency.
Pre-flotation desliming with hydrocyclones enhances Li₂O recovery and concentrate grade.
Compact design and low maintenance of hydrocyclone systems contribute to overall plant availability and cost-effectiveness.
