Partial Roasting of a PGM Concentrate

Roasting tests were conducted in a bench-scale rotary kiln on a sample of Merensky concentrate supplied by Lonmin. The kiln was purged with air to maintain high oxygen partial pressures (~0.21 atm O₂). Test temperatures from 350 °C to 700 °C and residence times from 2 to 30 minutes were explored.

Roasting an overview ScienceDirect Topics

K.G. Thomas, A.P. Cole, in Gold Ore Processing (Second Edition), 2016 Abstract. Roasting of ores and concentrates can be defined as the heating of a material to cause reaction and the expelling of volatile matter without causing fusion. Oxidative roasting is used extensively to pretreat base and precious metal–bearing materials and to oxidize iron sulfides to generate sulfur dioxide for

Kiln vs flash calciner FLSmidth

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.
