Abstract :The recovery of rare elemeuts as by-produets from The ash of coal or asphaltite has been important and the amount of them. has been found suitable for ecouomical recovcring. The asp¬haltite in the southeast Anatolia region insert ignore into journalissuearticles values(Turkey); contains molybdemım, vanadium, nickel and uranium. In the present work, the ash sample obtaiend from Şırnak asphaltite was leached with sulphuric acid. This leachatc contains 240 mg / L. Mo, 100 mg / L V, 71 mg,/ L Ni and 175 mg/ L Fe. This leach solution was passed through a cohımn of leugth 100 cm with an internal dia- meter of 1.5 cm. The metal ions were eluated with different H2SO4 Solutions. 97 % of the total Alo as 72 % püre molybdenum and 25 % Mo as a mixture with vanadium werc separated by elution with 0.01 N H2SO4 and 0.1 N H2SO4.
