AN OPTIMIZATION STUDY ON DISSOLUTION OF THE CALCINED COLEMANITE MINERAL IN METHYL ALCOHOL BY CO2 IN AN AUTOCLAVE SYSTEM USING TAGUCHI METHOD

The process of optimizing the dissolution of colemanite ore insert ignore into journalissuearticles values(2CaO.3B 2 O 3 .5H 2 O); in methyl alcohol by CO 2 in a high-pressure reactor was evaluated by using the Taguchi method. Optimum conditions for the cholemanite mineral were determined to be as follows: reaction temperature: 140°C, reaction time: 50 min, calcination time: 240 min, calcination temperature: 450 o C, solid-liquid ratio: 1/6 g.mL -1 , mixing rate: 500 cycle/min, pressure: 20 bar, grain size: -100 mesh and the amount of CaCl 2 : 7.5 g.
