Abstract

Se refiere a un proceso de extracción de boro a partir de salmueras de origen natural o industrial, o bien del boro contenido en un mineral que contiene boro, donde dicho proceso se realiza sin necesidad de ajuste de acidez y libre de solventes, a través de las siguiente etapas: a) proveer una forma de solución acuosa el material que contiene boro de una salmuera natural o industrial, o de una solución suspensión de un mineral particulado que contiene boro; b) adicionar el extractante, cloruro de Bario; c) separar el precipitado de borato obtenido de la etapa anterior; d) disolver e hidrolizar el precipitado para obtener ácido bórico.It refers to a boron extraction process from brines of natural or industrial origin, or from the boron contained in a mineral that contains boron, where said process is carried out without the need for acidity adjustment and free of solvents, through the following steps: a) providing an aqueous solution form of the boron-containing material from a natural or industrial brine, or from a suspension solution of a particulate boron-containing mineral; b) adding the extractant, Barium chloride; c) separating the borate precipitate obtained from the previous step; d) dissolve and hydrolyze the precipitate to obtain boric acid.
