dc.description | This work intends to document the use of phosphoric rock to obtain thermophosphates, from phosphorus sources, from the municipalities of Iza and Sogamoso, Boyacá. The IFA report indicates that the global demand for fertilizers in relation to P2O5 was 45,4 Mt in 2019, and the prospects for phosphates to obtain products could reach 112 Mt by 2022. To achieve this purpose, the method of calcination in an electric oven is reported as one of the most common techniques for the concentration of P2O5. In this sense, a design of factorial experiments 23 was applied, with two levels (low and high) and three factors: temperature (900°C and 1200°C), calcination time (3 and 5 hours) and source of the mineral (RFIZA and RFPC); the particle size (≤0,149 mm) remains constant. The results obtained show an increase in phosphorus concentration in the processed samples, especially those that were subject of higher calcination times and higher temperatures. | spa |
dc.description.abstract | Este trabajo pretende documentar el aprovechamiento de roca fosfórica para la obtención de termofosfatos a partir de fuentes de fosforita provenientes de los municipios de Iza y Sogamoso, Boyacá. El informe de la IFA indica que la demanda global de fertilizantes en relación con el P2O5 fue de 45,4 Mt en 2019, y las perspectivas de los fosfatos para la obtención de productos podrían llegar a 112 Mt para el año 2022. Para lograr este objetivo, se reporta el método de calcinación en horno eléctrico como una de las técnicas más comunes para la concentración de P2O5. En tal sentido se aplicó un diseño de experimentos factorial 23, con dos niveles (bajo y alto) y tres factores: temperatura (900°C y 1200°C), tiempo de calcinación (3 y 5 horas) y fuente del mineral (RFIZA y RFPC); el tamaño de partícula (≤0,149 mm) se mantuvo constante. Los resultados obtenidos muestran un incremento de la concentración de fósforo en las muestras procesadas, especialmente las que fueron sometidas a mayores tiempos de calcinación y mayores temperaturas. | spa |
