METHOD FOR PROCESSING NON-FERROUS METALURGING SLINGS.

摘要

Non-Ferrous Metallurgy Slag Processing Method "The present invention is correlated with a non-ferrous metallurgy slag processing method containing iron and valuable metals to produce a clean slag free of harmful substances and valuable metals, or reduced in one and suitable in that form for building material.The use as slag is reduction furnace (18), with the help of reducing agents (19), so that at least 5% of slag iron is reduced to At the same time, some of the valuable metals, such as zinc, lead, arsenic and cadmium 15 vaporize, the reduction furnace contents 18 are continuously mixed to prevent the separation of a metal phase from the slag. generated slag-metal (21) is discharged from the cooled, milled and milled reduction furnace (18) to give a finer size .. finally, a metal fraction (26) is separated of a clean slag (25).
