A process for the removal of substantially chromium free sulfate from aqueous alkali metal solutions containing chromate and sulfate which includes mixing said solutions having a pH of between about 2.5 and 4.5 with a calcium-containing material for a time and at a temperature sufficient to form a gypsum precipitate and separating said gypsum precipitate from said solutions ; as well as a process for the production of alkali metal chlorate by electrolysis of alkali metal chloride including said removal.
Méthode pour l'élimination de sulfate pratiquement exempt de chrome dans des solutions aqueuses de métaux alcalins, renfermant du chromate et du sulfate, consistant à mélanger des solutions dont le pH se situe approximativement dans une plage de 2,5 à 4,5 avec une matière renfermant du calcium pendant une période et à une température suffisantes pour former un précipité de gypse, et à séparer ce précipité desdites solutions; procédé pour la production de chlorate de métal alcalin par électrolyse de chlorure de métal alcalin, incluant l'élimination mentionnée plus haut.
