Sphalerite Leaching in Acid Media: a Review

open access: yesMetallurgical and Materials Data, 2023
The reserves of rich ores, from which the production of zinc by the existing conventional roasting-leaching-electrowinning process is technologically possible and economically justified, are decreasing year by year. For this reason, increasing attention has been directed towards researching the possibility of obtaining zinc from complex polymetallic ...
