Pyrometallurgy Roasting Smelting Refining Electrowinning

Typical safe flows are about 7m3/h for a 600x600 cell, 14m3/h for an 800x800cell and 20m3 for a 1000x1000 cell. The EW reaction produces acid at the surface of the anode so you need enough caustic to neutralize the acid and enough mixing to contact the acid with the caustic before it attacks the anode.
