Abstract :The main raw material used in the production of Sr metal and its compounds is SrSO 4 (celestite) mineral and Turkey has valuable Sr mineral deposits. One of the important steps in the production of Sr compounds is the production of strontium oxalate compound that does not contain alkali compunds as contamination. Strontium is used as a primary raw material in the production of oxalate, superconducting material and luminescence. In this study, the in situ conversion of SrSO 4 into SrC 2 O 4 .H 2 O by ammonium oxalate is investigated and the effect of rotation speed, ball / sample ratio and solution concentration on the conversion reaction has been determined. It was found that the conversion of SrO 4 to SrC 2 O 4 .H 2 O was increased with the increase in mole ratio of (NH 4 ) 2 C 2 O 4 to SrSO 4 . The maximum conversion, above 70 %, was achieved by using (NH 4 ) 2 C 2 O 4 / SrSO 4 mole ratio: 1.5, rotation speed: 500 rpm and ball / sample ratio: 13.Keywords : Celestite, strontium oxalate
