The results showed that the jarosite/alunite residue was dissolved in the high alkaline environment of the mortar, producing CaSO 4 · 2H 2 O and AlOOH. During hydration, gypsum and some of the Ca(OH) 2 were consumed, together with aluminum hydroxide in order to produce ettringite, a fact that improved the mechanical behavior of the produced mortars.
Alunite is a sulfate mineral, it occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks. It is formed by the action of sulfuric acid bearing solutions on these rocks during the oxidation and leaching of metal sulfide deposits.

Taking into account the processing capacity of Ganja Alumina Plant (150,000 tons of alumina per year), this method allows the production of fertilizer, potassium sulfate (370,000 tons per year), coagulant for purification of water from mechanical impurities (49,000 tons per year), table salt (NaCl) (126,000 tons per year), and quartz sand for nonferrous casting and production of construction materials (300,000 .
Alunite is a potential resource for production of alumina and potassium sulfate. Hydrometallurgy is the conventional process employed for this purpose and direct leaching in KOH is suitable as one of the process steps because it does not require prior calcination. In this paper dissolution kinetics of pure natural alunite in KOH is described.
