Abstract
La invencion se relaciona con un metodo para mejorar el resultado del lavado y la filtrabilidad de un material de desecho finamente molido generado en la industria metalurgica. De acuerdo con el metodo algun otro solido finamente molido es agregado al primer precipitado de desecho antes de la filtracion, el cual es tambien removido del proceso, y el cual permanece estable en las mismas condiciones que el primer precipitado de desecho.
