Recovery of cobalt, molybdenum, nickel and vanadium from an aqueous
ammonia and ammonium salt solution by precipitating vanadium and
subsequent serial ion exchange
摘要:
A process for separating metal values from an aqueous stream containing vanadium, molybdenum, nickel and cobalt. Vanadium is first precipitated, and then nickel, cobalt, and molybdenum are removed by serial ion exchange.
