FMR 4 – Step Processing To Win Fine Metals
Situation: As in ore and slag processing there are in several waste mixes , even also in filter dust, metals in different concentrations and grainsizes contained. Very often there are losses in the fines. Stockpiles of tailings are existing and waiting for a new processing technology to win the worthy elements economically. The reason for metal losses in the case of filterdust is a melting of plastic content by heat if there is a dry processing with fine particles . Therefor we make the last step of attrition in wet processing to avoid remelting by temperature influence.
