Leaching of metal oxides - UBC Library Open Collections

The leaching of metal oxides in acids has been investigated. The experiments were focussed on the leaching of ferric oxides in perchloric, hydrochloric, sulphuric, oxalic and malonic acids. Additional studies were made of the leaching of aluminum, cuprous, cupric and manganous oxides in the above acids. In dilute solutions of the acids (<0.2M), the rates of leaching of the oxides showed a
