Magnezit cevherinin sulu ortamda kükürtdioksit gazı ile çözündürülmesi ve çözünme kinetiğinin incelenmesi

Abstract

In this study; the kinetic of reaction between magne6i teand sulfur dioxide gas in wa'ter has been investigatec'!,considerating production of various magnesium compoundsespecially; H9(HS03) 2 from mo.gnesite.The effects of magnesite particle si ze, solid to liquidratio, gas floH rate, stirring speed and temperature /-Jerestudied on ss:>lubili ty of magnesite from Erzururn-HasanJ,-aleregion. The obtained experimental data /-Jere analysed onthe basis of the unreacted shrinJ~ing core model for nonecatalyticheterogen reaction.AS a result, it /Vas found that tile dissolution is chemicaly-controlled. 'I'he activation energy for dissolution ofmagnesite was calculated as 81,04 kJ.mol-1.
