Abstract
Un procedimiento para producir una solución de molibdato de amonio purificada a partir de trióxido de molibdeno de calidad técnica, caracterizado por calentar el trióxido de molibdeno de calidad técnica a una temperatura lo suficientemente elevada y durante un período de tiempo lo suficientemente elevada y durante un período de tiempo lo suficientemente prolongado para hacer el potasio soluble en agua caliente, enfriar el trióxido de molibdeno calentado hasta una temperatura menor de aproximadamente 400ºC. a un régimen de enfriamiento de por lo menos aproximadamente 30º C. por minuto, lixiviar el trióxido de molibdeno enfriado con agua caliente para lixiviar el potasio del mismo, separar el trióxido de molibdeno del agua de lixiviación, digerir el trióxido de molibdeno separado en una solución de amonio para formar una solución purificada de molibdato de amonio y separar la solución purificada del molibdato de amonio de los sólidos no digeridos.
