Mechano-Activation and SHS of Difficultly Taken Ore
DOI:
https://doi.org/10.18321/ectj84Abstract
Technological parameters of opening refractory ores by mechanical activation which determine remaining and the morphology of the samples after mechanical activation, SHS synthesis and the leaching process has been defined. Mechano-chemical activation of arsenopirita in different modes increases process have been defined. Optimal conditions for activation: time - 30 min at a ratio of grinding media and mineral 2:1. Leaching rate was higher for the activated samples the same amount of time than the original. Extraction of gold for the chosen optimum conditions is 93.2-95%.References
