dc.descriptionSeventy-five percent of the phosphate rock extracted is used for the production of phosphoric acid. However, during the leaching process, it is also possible to dissolve calcium compounds, allowing for the extraction of phosphorus and calcium ions from the resulting solution. This study focused on the application of hydrometallurgical processes directly to phosphate rock to obtain calcium phosphates with potential applications in the manufacture of biomaterials. After a physicochemical characterization of four phosphate rock samples, one sample was subjected to a hydrometallurgical process using nitric acid. The leachate was then neutralized with sodium hydroxide to achieve a pH between 4.5 and 12. One sample of the precipitate was dried at ambient temperature, while another was dried at 70°C. Depending on the pH and the Ca/P molar ratio, three types of calcium phosphates were obtained. X-ray diffraction analysis identified the three phases as octacalcium phosphate, hydroxyapatite, and monetite, all of which are recognized as biomaterials.
dc.descriptionEl 75% de la roca fosfórica extraída se destina a la producción de ácido fosfórico, pero en el proceso de lixiviación también es posible disolver compuestos de calcio, permitiendo obtener iones de fósforo y calcio en la solución resultante. El presente trabajo se centró en la aplicación de procesos hidrometalúrgicos directamente a la roca fosfórica para la obtención de fosfatos de calciocon potencial aplicación para fabricación de biomateriales. Luego de una caracterización fisicoquímica de 4 muestras de roca fosfórica, una muestra de roca fosfórica fue sometida a un proceso hidrometalúrgico con ácido nítrico. El lixiviado se neutralizó con hidróxido de sodio a pH entre 4.5 y 12. Una muestra del precipitado se secó a temperatura ambiente y la otra a 70°C. Con este proceso, dependiendo del pH y la relación molar Ca/P se obtuvo tres tipos de fosfatos de calcio. A través de la difracción de rayos X se identificaron que las tres fases eran fosfato octacálcico, hidroxiapatita y monetita, las cuales son reconocidas como biomateriales.
