Abstract

Procedimiento de ataque oxidante a alta temperatura de minerales, que contienen al menos un metal perteneciente al grupo constituido por uranio, vanadio, y molibdeno, por un licor acuoso que contiene bicarbonato de sodio y carbonato de sodio en presencia de oxígeno libre insuflado en el medio reaccional, procediendo la separación de los estériles y del licor del ataque que contiene el o los metales solubilizados caracterizado porque el mineral es tratado por un licor acuoso que contiene en su mayor parte bicarbonato de sodio y en menor parte carbonato de sodio, de tal modo que la relación másica bicarbonato de sodio/carbonato de sodio sea al menos igual a 1,5 , porque se inyecta oxígeno libre en el medio reaccional de tal modo que la presión parcial de oxígeno en el reactor se sitúe en el intervalo de 0,1 a 20 bares, y porque la temperatura del medio reaccional es mantenido entre 160 y 300ºC durante un tiempo a lo sumo igual a 6 horas.
