Process for the production of synthetic dolomite

摘要

A process for the production of synthetic dolomite comprising: grinding a dry and low impurity level mineral dolomite; incorporating additives selected from the group consisting of iron as Fe2O3, silica (SiO2) and magnesium hydroxide Mg(OH)2, calcium hydroxide Ca(OH)2 or a combination of both, in order to react and integrate dolomite impurities as the desired silica (SiO2), iron (Fe2O3), and alumina (Al2O3), in the dolomite; wholly mixing these additives with the ground dolomite in a mixer machine; compacting the mixed materials in order to form briquettes; sieving the briquettes of compacted material to eliminate fines; burning the briquettes to a temperature of 1,700 to 2,200 DEG C. to guarantee a complete sintering; cooling the briquettes and sieving the cooled briquettes.
