Chlorination of boron containing ores by mixture of gaseous chlorine and sulfur chlorides

Present article is devoted to chlorination of boron containing ores by mixture of gaseous chlorine and sulfur chlorides. The low temperature chlorination of initial calcined danburite ore of Ak-Arkhar Deposit was studied. The analysis results of initial materials and reaction products of decomposition of danburite ores by gases mixture were confirmed by means of X-ray phase method, differential-thermal analysis and infrared spectrometry analysis. The optimal conditions for chlorination of calcined danburite ore, including chlorination temperature, process duration and particle size were proposed.
