Sindesar Khurd Mine (SKM) tailings are disposed into tailing ponds. Seeking solution for profitable recovery of metals from the mine tailings, which are rich in minerals and reduce the tailings by 50,000 Tons.
Ore from SK mine is treated in a mill, of which about ~90% waste i.e tailings is generated. Presently the tailings are dumped in tailing ponds (~45%) or utilized in paste fill (~55%), thus the metal content in tailings is getting lost and causing an environmental liability. There is an opportunity to recover precious metals & rare earth elements along with base metals from tailings. An innovative solution is required to recover metals from SKM tailings. The tailing Dam is live, thus metal recovery from Fresh tailings will be targeted instead of legacy tailings.
Typical assay of tailings- Zn <0.2%, Pb <0.1%, Ag-20ppm, Fe-14%, Al-2.8%, Mn- 2.2%, Mg-3.8%
