High-rate Thickener: maximise throughput and water recovery in mining dewatering

May 27, 2026

The FLS High-rate Thickener delivers high-capacity solid-liquid separation in a compact footprint, helping mining operations maximise throughput while recovering more process water. Designed to produce denser, more consistent underflow, high-rate thickeners process roughly 12 times the throughput of conventional thickeners of a similar size, reducing both equipment footprint and overall dewatering cost. Whether applied in tailings dewatering, concentrate thickening or process water recovery circuits, the High-rate Thickener supports sustainable water stewardship and lower total cost of ownership across the mine lifecycle. Backed by FLS process knowhow built over more than a century, every thickener is designed to suit your specific application, ore type and water balance requirements.
