摘要
The process for removing titanium metal and alloys from nickel metal, nickel metal alloys, cobalt metal and cobalt metal alloys by leaching out the titanium metal and/or alloys with a hydrofluoric acid solution, oxidizing Ti.sup.+3 to Ti.sup.+4 salts in the leached metals or alloys with an aqueous oxidant, and rinsing the leached metal with water to yield nickel metal, nickel metal alloys, cobalt metal, and/or cobalt metal alloys substantially free of titanium and tin.
