Document Type and Number:
WIPO Patent Application WO/2020/057266
Kind Code:
A1
Abstract:
A copper smelting device, comprising a furnace body (100), a feeding port (101), a smoke outlet (106), a slag outlet (102), a copper matte port (103), and a primary air vent (104). A copper matte layer (112), a slag layer (113), and a gas layer (114) are sequentially arranged in the furnace body (100) from bottom to top. The feeding port (101) is arranged on a top wall of the furnace body (100). The smoke outlet (106) is arranged on the top wall of the furnace body (100). The slag outlet (102) is arranged at one end of the furnace body (100). The copper matte port (103) is arranged at an end of the furnace body (100) opposite to the slag outlet (102), and the copper matte port (103) is located at the bottom of the copper matte layer (112). The primary air vent (104) is located on a side wall of the furnace body corresponding to the slag layer (113), and is used to blow oxygen-enriched air into the slag layer (113). The dimensions in the width-wise direction of the inner wall corresponding to the slag layer (113) are greater than 2.5 m and less than or equal to 4.5 m so as to expand the scale of single furnace processing of concentrates, thereby improving labor efficiency and reducing operating costs.
