LEAD PASTE SODIUM DESULPHURIZATION SYSTEM

The lead paste slurry which from breaking and separation machine are as raw material for desulphurization. The process is shown in below:

The paste pumped into desulphurization tank, add the desulfurizer（sodium carbonate） to conduct desulfurization reaction, and stirred sufficiently. The mixed liquid of lead paste will be returned to desulphurization tank after compulsory desulphurization.

After the reaction, the liquid and solid are separated by the filter press. The lead cake (desulphurization lead paste) is entered into the smelting system. The filtrate (sodium sulfate) are entered into filtrate tank.
