2 re-election plants for the treatment of alluvial sands should be dispersed and coarsely selected. Focus on the selection process. The crude ore is selected from polyvalent metal have lower levels of sludge and gravel, should preclude the washing operations.
3 ore with useful minerals in uneven thickness and coarseness shall be selected according to the content of metal and the dissociation of useful mineral monomers. For large and medium-sized concentrating plants, when the grades and properties of raw ore are very different, the process of grinding and selecting according to the rich and poor and optional subsystems should be adopted.
4 ores with fine minerals embedded in fine minerals shall be processed by stage grinding and centralized treatment of slime.
5 closed-circuit grinding operations, when the graded particle size is greater than 0.2mm, it is advisable to use the screening machine to close the circuit or set appropriate sorting equipment in the circuit.
For each of the 6 stages of the selection, the concentrates or coarse concentrates should be obtained and some of the tailings should be discarded.
The feeding of 7 re-election operations shall strengthen the operations of slag separation, grading and mud removal, and strictly carry out the separation of mud and sand. When the content of sulfide in the ore is sufficient to interfere with the sorting, effective desulfurization measures should be taken.
The intermediate products of the 8 re-election plants should be separately selected according to the nature of the materials. Fuzhong Mine should adopt multi-selection and less grinding, and select post-grinding process. Poor mines should adopt the first grinding and post-selection process. Medium mines with complex nature and difficult to separate should not be re-elected. It is advisable to use an adaptive joint process.
Before the 9 pieces of slime are sorted, they should be graded and de-sludged, and narrow-level selection is carried out. When there are many waste fine muds in the slime, it is advisable to adopt the process of grading and sorting after de-sludge.
