Autoclave reduction of jarosites and other metal sulfates : a new approach to major waste problems

Abstract

Industrial jarosite is a waste product of the zinc industry. It is considered a serious environmental problem, due to the quantity produced and the mobile hazardous metals it contains. Over 50 million tons are already stored worldwide. The jarosite sludge autoclave treatment process described in this thesis is a technically and economically feasible alternative to storage, which is only a temporary solution.
