Multi-metal smelting/blowing method

The invention discloses a multi-metal smelting/blowing method which comprises the following steps: S1, performing fine grinding on quartz particles to obtain quartz powder with preset fineness; s2, according to the adding amount of the multi-metal material, the amount of oxygen-enriched air and the using amount of quartz powder and pulverized coal are calculated; s3, the multi-metal material is added into the furnace from the furnace top through quantitative feeding and conveying; s4, oxygen-enriched air, quartz powder and pulverized coal are sprayed into a slag layer in the furnace through a spray gun and rapidly react with the high-temperature melt, and metal extraction is conducted; the metal extraction mode is smelting or blowing. According to the multi-metal smelting/blowing method, silica powder and oxygen-enriched air are blown into the furnace together, generation of magnetic iron Fe3O4 is reduced, and the oxygen potential in melt is reduced. According to the multi-metal smelting ...
