Title:
COPPER SLAG DEPLETION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/242607
Kind Code:
A1
Abstract:
A copper slag depletion device and method. The device comprises a copper slag depletion treatment furnace (10) and a wire feeding device (20), wherein the copper slag depletion treatment furnace (10) uses electrothermal or plasma heat as a heat source; the copper slag depletion treatment furnace (10) is provided with a copper slag inlet, a wire feeding hole and a matte opening; the copper slag inlet is used to introduce copper slag (a), and the matte opening is used to discharge copper matte (c) obtained by a reduction and depletion treatment; the wire feeding device (20) is used for feeding a carbon powder wire (b) into the copper slag depletion furnace (10) by means of the wire feeding hole so as to perform a reduction and depletion treatment on the copper slag (a). The copper slag depletion device is capable of improving the reduction and depletion efficiency of copper slag, and has a short process, low costs, may simultaneously recover heavy metals such as lead and zinc in the slag, and other effects.
