Dump leaching processing method for waste furnace-constructing refractory materials of aluminum electrolytic bath

Disclosed is a d ump leaching processing method for waste furnace-constructing refractory materials of an aluminum electrolytic bath. The method comprises the following steps that the waste furnace-constructing refractory materials which are sorted from bath residues generated in overhaul the aluminum electrolytic bath are crushed and screened, and then pre-leaching, dump leaching and washing are circularly conducted on the waste furnace-constructing refractory materials; generated pre-leached liquid and dump leached liquid are subjected to oxidative decyanide treatment and then are filter-pressed; and CO2 gas is led in filter-pressed filtered liquid, then the filter-pressed filtered liquid is subjected to carbon-neutralization treatment, through concentration and crystallization, sodium salt is recovered, and mixture of fluorinated NaHCO3, fluorinated Na2CO3 and NaF is obtained. By means of the dump leaching processing method, innocent treatment and comprehensive using of the waste furnace-constructing refractory materials of the aluminum electrolytic bath can be achieved.
