description	PURPOSE:To effectively make the scrap wood contg. harmful matter harmless by melting the ash contg. harmful matter formed by burning scrap wood contg. harmful matter such as copper in an incinerator in the high-temp. furnace of copper producing equipment along with copper ore, and separating the harmful matter. CONSTITUTION:The chipped scrap wood 1 contg. harmful matter such as Cu is sent into an incinerator 2 by a conveyor, etc., and burned. The formed ash is supplied to a blender 4, then transferred to a drier 6 along with the copper ore 5, and charged into a flash smelting furnace 7. Since the furnace 7 is filled with an oxidizing atmosphere and held at a high-temp. of about 1400 deg.C, the Cu in the ash forms Cu2S-FeS along with the Cu in the ore 5, and is recovered as crude copper in a convertor 8. Although a part of Cr forms harmful hexavalent Cr during incineration, all the Cr is converted to trivalent Cr, fixed in slag, and discharged from a slag cleaning furnace 9.
