Now complete the following example -
Input: The present invention refers to a method an and an apparatus system for the treatment of floating slag in order to produce coarse high purity graphite, wherein a concentrate is formed which contains at least about 90 percent of carbon, said concentrate being treated with a diluted acid solution, and the paste being subsequently subjected to attrition aided by an adjuvant so as to form a novel synthetic laminated graphite having a carbon content of 99+ percent by weight, with at least 70 percent of the mass retained in the mesh +100, and a total recovery of graphite carbon from the feeding step of more than 85 percent by weight.
Output: Se dan a conocer un método y un sistema de aparato para la beneficiacion de la escoria flotante a fin de producir grafito de gran pureza grueso en donde se forma un concentrado que contiene por lo menos aproximadamente 90 por ciento de carbono, se trata con una solucion de ácido diluida, y la pasta luego se somete a una atricion ayudada por un adyuvante para formar un grafito lamelar sintético novedoso de contenido de carbono de 99+ por ciento en peso con por lo menos el 70 por ciento de la masa retenida en la malla +100 y una recuperacion total del carbono grafítico a partir de la alimentacion de más del 85 por ciento en peso.
