and other minerals. However 1 and D. D. Harbuck ABSTRACT The U.S. Bureau of Mines conducted laboratory studies on sulfuric acid (H2S04) digestion of alunite [KA1a(S04)z(OH)6] as a means for treating domestic deposits of this mineral.of alumina additional compounds can be present.Abstract Alunite was considered as a potential alternative resource for potassium and alumina production. The disintegration of alunite was a principal step to extract valuable components and therefore was highly relevant to great and efficient utilization. In this research

or Ca(OH) 2 to an ...High-temperature roasting of alunite in the presence of K2CO3 gives rise to a reaction that results in up to an 80% recovery of its potassium content as K2SO4 by leaching of the roasted mixture. K2SO4 is also generated from the reaction between the added K2CO3 and the S03 driven off during roasting of the alunite. This limits the environmental and corrosive problems involved in the thermal ...Alunite Franchise | 16 followers on LinkedIn. Franchise Opportunity Available!
