| description | 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.
