High Pressure Acid Leach

High Pressure Acid Leach Overview The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore...

Uranium processing

Sulfuric acid leaching circuits commonly employ either manganese dioxide or chlorate ion to oxidize the tetravalent uranium ion (U 4+) to the hexavalent uranyl ion (UO 2 2+) Typically, about 5 kilograms (11 pounds) of manganese dioxide or 15 kilograms of sodium chlorate per ton suffice to oxidize tetravalent uranium...
