The article focuses on processes used to obtain hydroxyapatite from phosphate rock in the municipality of Pesca (Department of Boyacá, Colombia) by leaching with nitric acid. An analysis was carried out to evaluate the influence of different concentrations of leaching acid and treatment time on the recovery of phosphorus and calcium ions. The results indicated that maximum recovery of phosphorus and calcium ions was achieved by increasing concentration to 5M. The influence of the concentration of the precipitating agent was also analyzed and it was found that, although increased concentrations improve the pH adjustment rate, the purity of the HAp obtained decreases at higher concentrations, possibly due to the formation of other species associated with sodium hydroxide. Following washing with deionized water, pure HAp was obtained as a final product, which was characterized using XPR, XRD, SEM/EDS and FTIR.

El presente trabajo se centra en la obtención de hidroxiapatita (HAp) a partir de roca fosfórica proveniente del municipio de Pesca del departamento de Boyacá, por medio de la lixiviación con ácido nítrico. Se llevo a cabo un análisis para evaluar la influencia de la concentración del ácido lixiviante y el tiempo del tratamiento en la recuperación de iones de fósforo y calcio. Los resultados indicaron que al incrementar la concentración ácida hasta 5M se logró la máxima recuperación de dichos iones. También se analizó la influencia de la concentración del agente precipitador y se encontró que, si bien, el aumento en la concentración mejora la velocidad de ajuste del pH, se observa una disminución en la pureza de la HAp obtenida, esto posiblemente debido a la formación de otras especies asociadas al hidróxido de sodio. Después de un lavado con agua desionizada se obtuvo como producto final, HAp pura, la cual fue caracterizada por FRX, DRX, SEM/EDS y FTIR.
