鉛精錬のための方法および装置
Document Type and Number:
Japanese Patent JP5480502
Kind Code:
B2
Abstract:
A method for producing lead involves feeding lead concentrate, flux and solid fuel passing to a feed preparation unit. The prepared, mixed feed is then passed to a lead smelting furnace, such as an ISASMELT furnace or other top entry, submerged lance furnace. Air or oxygen, is injected into the molten charge in the ISASMELT furnace via the submerged lance. The feed mixture is converted into lead bullion and a lead-containing slag. The slag removed from the furnace is formed into lumps having a desirable size range. The slag lumps, together with coke and flux are fed into a blast furnace. In the blast furnace, the slag is converted into lead bullion and discard slag. The lead bullion removed may be subsequently fed to a lead refinery for further treatment.
