Abstract
Process for recovering boron indices from borate, calcium mineral, characterized by comprising: leaching said mineral with a hot aqueous solution of ammonia and a hot aqueous solution of carbon dioxide, said hot aqueous solutions being maintained at temperatures below 83º C , the ratio of ammonia to carbon dioxide being found within the ratio 2: 1 to 1: 1 to form ammonium borate in solution and solid calcium carbonate; separating the liquor thus formed from said solid calcium carbonate and said mineral; and cooling said liquor to precipitate said ammonium borate.
