2500 TPD Lithium Spodumene Flotation Plant with Hydrocyclones in Australia

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:

• Hydrocyclones for initial thickening of spodumene concentrate
• Followed by thickener and press filter for final dewatering and dry stacking

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.
