FOER FARING FOR OXIDIZATION OF FERROJONERS AND ETCARS OF SULFATEX TRACTIONS

摘要

An improvement in a process for selectively removing iron in a ferric state from a sulfate leach solution is disclosed. The improvement comprises selectively oxidizing ferrous ions present in the solution to the ferric state by adding an essentially stoichiometric amount of a peroxosulfuric compound to the solution.
