| titleOfInvention | Method and equipment for purifying calcium chloride from fluorine-containing solid waste |
| abstract | Relates to a method and equipment for purifying calcium chloride from fluorine-containing solid waste, which comprises the steps of firstly carrying out carbonation reaction on the fluorine-containing solid waste, and then separating a purification interference source, such as sulfate, in the carbonated fluorine-containing solid waste; and then, carrying out hydrochlorination on the carbonated fluorine-containing solid waste after separation, carrying out solid-liquid separation and cyclic leaching after acid leaching of the hydrochlorination, and purifying calcium chloride from the acid leaching solution and the derived solution of the partial acid leaching in the cyclic leaching, so that the interference of sulfate on the subsequent purification of calcium fluoride can be avoided, and the yield of the intermediate product calcium chloride can be improved. |
