Abstract

The process
of optimizing the dissolution of colemanite ore (2CaO.3B₂O₃.5H₂O)
in methyl alcohol by CO₂ 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 ^oC,
solid-liquid ratio: 1/6 g.mL^-1, mixing rate: 500 cycle/min,
pressure: 20 bar, grain size: -100 mesh and the amount of CaCl₂: 7.5
g.  

Keywords
