摘要
The present invention relates to a method and an apparatus for recovering copper, bronze and lead by allowing methane gas to flow into a reactor and heat-treating a mixture of copper oxide, tin oxide and lead oxide under a temperature condition of 700-900° C., and comprises the steps of: placing a mixture of copper oxide, tin oxide and lead oxide in a reactor; increasing the temperature inside the reactor; and allowing a reductive gas to flow into the reactor so as to heat-treat the mixture.
