Problems solved by technology

However, the anode residues that are put in are due to reasons such as fast feeding speed, large single piece weight, and fixed position, which cause the residues to partially accumulate in the lead pot 4 and block the feeding port, making continuous feeding impossible.
Pyrometallurgy is currently the main processing method in China, and smoke pollution and lead vapor pollution have not been effectively controlled due to technological limitations

Abstract

The invention discloses an anode residual treatment process suitable for non-ferrous metal pyrometallurgy. The process comprises the following steps of: 1, washing anode residual sheets by using cleanwater; 2, making the anode residual sheets into blocks; 3, drying flow: carrying out drying to remove moisture on the surfaces of the anode residual blocks (1); 4, putting: continuously putting the anode residual blocks (1) into a recovery device; and 5, smelting recovery: putting the put anode residual blocks (1) into a smelting device to make a new anode plate. Among above steps, material conveying is carried out by adoption of a conveying line (2). The process has the advantages of being short in residual smelting time, continuous in putting, high in working efficiency and good in smoke collection effect.

Description

technical field [0001] The invention relates to the field of non-ferrous metal smelting, in particular to an anode butt treatment process suitable for non-ferrous metal pyro-smelting. Background technique [0002] Nonferrous metal smelting raw materials are mixtures of various metals, including gold, silver, copper, zinc, tin and other precious materials. The pyrometallurgy process is the process of gradually separating, extracting and purifying various precious metals from liquid raw materials. At present, the smelting process of domestic non-ferrous metals mainly adopts fire smelting-heating the molten raw material liquid metal liquid to different temperature ranges "usually 400°C to 1100°C", so that a certain metal is precipitated as a solid mixture and floats in the liquid surface, and then the mixture is removed from the heating pot and separated from the liquid, which completes a pyro-smelting cycle. [0003] Taking the lead fire smelting process as an example, accor...
