Abstract: |
Large quantities of cyanide-containing tailings produced in cyanidation processes need to be de-cyanided prior to final disposal. Effects of washing ratio on efficiency of replacement washing of cyanide tailing pressure-filtering cake produced by all-slime cyanidation process were investigated. The results of small-scale laboratory tests show that washing efficiency rises approximately linearly with washing ratio within 2—3. Rising washing ratio beyond three results very limited impact on washing performance. Industrial-scale tests confirm that there is a suitable range for selecting of washing ratio to compromise cyanide washing efficiency and facility utilization. |
