  Face sheet - NOVA

  Though dry processes are considered to be less efficient than wet processes (Lockhart, 1984), dry separation does have advantages including lower costs for product transportation, dewatering and thickening to recover process water and tailings management. Solid-gas fluidized beds are one of the options for dry separation.
