Challenges in metallurgical drying include handling the abrasive, dense, and sometimes corrosive nature of mineral materials, which demands robust and durable equipment.
Achieving the precise moisture level is critical; too much moisture affects processing and transportation costs, while over-drying can cause material degradation or dust issues.
Variability in mineral characteristics requires careful dryer design and operation, often supported by testing to optimize retention time, airflow, and temperature. Additionally, high energy consumption and managing environmental emissions from drying processes pose ongoing challenges in metallurgical drying operations(AusIMM, n.d.).
