Research on the Design Alternatives of Unclassified Tailings Paste Fill for a Foreign Lead Zinc Mine
The paper analyzes the characteristics of unclassified tailings paste fill.Taking an overseas lead zinc mine as an example,the tests were conducted on the physical and chemical properties,particle size composition,and strength ratio of the unclassified tailings.Based on the test results,two alternatives are proposed:deep cone thickener fill process and disc filter fill process.After process comparison,the deep cone thickener fill preparation process was selected,and the selection and calculation of the main equipment of the fill preparation station were described in detail.
