In the metallurgical industries, POWDER high-performance ball valves can operate and isolate in extreme environments with corrosive and abrasive solids for isolating and directing the flow of hot slurry within HPAL, POX and other autoclave applications.
High Pressure Acid Leaching
HPAL was developed to extract mineral from concentrate nickel laterite ores by injecting an acid lixiviant and high-pressure steam into slurry feed in an autoclave vessel.
