Addn. of paper residue from paper manufacturing into metal producing process - as redn. agent in the pyro-metallurgical mfr. of metal, to reduce cost of coke and wood

摘要

Method of adding carbon as reducing agent into a process for pyrometallurgically producing metals consists of adding the paper residue resulting from the production of paper. The waste residue from the paper manufacturer may be added to the metal production process as loose or briquetted material with the paper material being predried to a required moisture content. USE/ADVANTAGE - In the production of Zn, ferrochrome, ferromanganese, ferromolybdenum, ferrovanadium, Pb, Sn and the working up of copper pyrites, etc.. Cost of obtaining coke or oak wood are minimised and the waste disposal costs for the paper manufacturer are reduced.
