Abstract
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. is disclosed. The method includes 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.
Claims8
An apparatus for recovering copper, bronze and lead from a mixture of copper oxide, tin oxide and lead oxide, the apparatus comprising:
- a reactor into which reductive gas is introduced;
- a mesh structure disposed inside the reactor, wherein a mixture of copper oxide, tin oxide and lead oxide is placed on a top face of the mesh structure;
- a recovering unit disposed below the mesh structure;
- a heater for heating an inside of the reactor;
- and
- a recovering line connected to an upper end of the reactor for recovering vaporized lead inside the reactor.
