Abstract
A method and device for producing a crude copper. The method comprises: mixing and reacting copper smelting molten slag (1), a carbon-containing reductant (2) and an inert gas (3) under pressure, the pressure of the inert gas (3) being 100 kPa to 800 kPa. The device comprises: a furnace body (4) and gas nozzles (411) disposed on the furnace body (4), the gas nozzles (411) being located on the sidewall of the furnace body (4) and connected to the center of the molten pool.
Claims7
A method for production of blister copper, comprising the following steps:
- in a production device, mixing copper-smelting molten slag, a carbon-containing reducing agent and pressurized inert gas followed by reaction to obtain blister copper and post-reaction slag, wherein the inert gas has a pressure of 100 kPa to 800 kPa, and wherein the production device comprises:
- a furnace body, which furnace body comprises a molten pool inside and is provided therein with a gas nozzle, a feed port, a blister copper discharge port and a slag discharge port;
- wherein the gas nozzle is disposed on the sidewall of the furnace body and leads to the middle part of the molten pool;
- and
- wherein the copper-smelting molten slag and the carbon-containing reducing agent are introduced to the production device via the feed port through a runner, respectively;
- the inert gas is charged to the production device via the gas nozzle.
