TK: Both the rotary kiln approach and the suspension calciner effectively convert spodumene. The primary consideration of which approach is best is the concentrate particle size distribution (PSD). Concentrate produced via dense media separation (DMS) often results in feed size from 3mm to as large as 12mm or sometimes larger.
