Recovery of magnesium chloride hexahydrate from carnallite ore
Abstract
Abstract THE VARIOUS STANDARD TEXTS ON MINERALOGY GIVE THE COMPOSITION OF CARNALLITE AS MGCL2.KCL.6H2O. IN INDUSTRIAL USAGE, THE TERM "CARNALLITE ORES" IS USED AS REFERRING TO THE FOREGOING SALT MIXTURE TOGETHER WITH VARIOUS OTHER SALTS SUCH AS SODIUM CHLORIDE AND OTHER INSOLUBLE MATERIALS WITHER AS A BROKEN ORE OR IN THE FORM OF A NATURAL DEPOSITE. I HAVE FOUND THAT BY TRATING CARNALLITE ORES WITH ANY ONE OF THE LOWER SATURATED MONOHYDRIC ALIPHATIC ALCOHOLS HAVING FROM 1 TO 4 CARBON ATOMS SUCH AS METHANOL, ETHYLANOL, PROPANOL, ISOPYOPYL ALCOHOL, N-BUTYL ALCOHOL, SECONDARY-BUTYL ALCOHOL, ISO-BUTYL ALCOHOL AND TERTBUTYL ALCOHOL, THE MAGNESIUM CHORIDE HEXAHYDRATE GOES INTO SUUTION LEAVING THE POTASSIUM CHLIRDE AND OTHER SALTS AND INSOLUBLE MATERIALS AS AN INSOLUBLE RESIDUE.
