MECHANICAL ACTIVATION OF WASTE COPPER SLAG IN THE PRESENCE OF REDUCTANTS
Maqola haqida umumiy ma'lumotlar
This empirical work looks into the technological raw material for the synthesis of zinc, mechanical activation of waste copper slag in the presence of reductants. On the phase makeup of the charge, the effect of mechanically activating slag with coal has been identified. Under the following circumstances, partial breakdown of zinc ferrite and fayalite has been observed: ratios of 1:2 for slag to coal, 4:1 for balls to powder, and 40 minutes for mechanical activation. It has been discovered, that zinc extraction from treated slag has been affected by hydrochloric acid leaching conditions. The largest amount of zinc that could be extracted into solution from activated slag was 33%, compared to only 9% from the original slag. The results demonstrated that the suggested technique for removing zinc from used copper slag is ineffective and should not be used in actual applications
