Traditionally, the beneficiation of lithium-bearing pegmatite ores can follow different routes, with flotation and Dense Media Separation (DMS) being the most common. The standard beneficiation routes, involving crushing, screening, and DMS, can produce a spodumene concentrate but cannot fully address the issue when schist is present in high proportions.

The goal is to remove schist early, typically 5 to 20% of ROM, before the DMS stage, improving feed quality and process selectivity. Since commissioning, the SBS installation has delivered improvements to CBL’s spodumene beneficiation circuit.
