Application of tetrachloroethylene mixing with water in comprehensive utilizing nickel anode sludge

The technology of sulfur recovering by the means of tetrachloroethylene mixing with water has its own special characteristics and advantages, comparing with other methods in the field of comprehensive utilizing nickel anode sludge. The technological parameters of every procedures are determined. The separatory filtration process is provided and carried out in order to guarantee the quality of sulphur. The new technology of sulphur recovering which is suitable for high sulphur materials, the advantages include: high concentration rate of previous metals, high leaching rate, low energy consumption, good production quality and recycling use of solvent.
