Abstract
Considering lack of lithium, the authors believe it is advisable to analyze dressability and producibility of spodumene concentrates from mine waste, specifically from tailings of Transbaikal Mining-and-Processing Integrated Works. The analysis includes mineral, chemical and grain-size compositions of raw material, as well as the capacity of spodumene to be separated and recovered. These characteristics make the basis for developing the dressing technology and process flowsheet for the indicated type of technogenic (i.e. resulted from production activities) deposits.
