Method and apparatus for recovering copper bronze and lead from a mixture of copper oxide tin oxide and lead oxide

摘要

The present invention relates to a method and apparatus for recovering copper, bronze and lead by introducing methane gas into a reactor and heat-treating a mixture of copper oxide, tin oxide and lead oxide under a temperature condition of 700°C to 900°C, Disposing a mixture of copper oxide, tin oxide, and lead oxide in the interior of the reactor, heating the interior of the reactor, and introducing a reducing gas into the interior of the reactor to heat-treat the mixture.
