Due to the change in composition of processed raw materials at Balkhash Copper Plant (BCP), it is required adjust technology used melt copper sulfide concentrates Vanyukov furnace (VF). It promising use additional carbon-containing fuel that burns bubbling zone increasing melting temperature and partially reducing slag oxides ensure autogenousity temperature. However, part solid does not burn w...
