Abstract
An operation method of a flash smelting furnace includes blowing a gas for dispersing raw material and contributing to a reaction, from a lance at an upper portion of a shaft so that the gas forms a spiral flow. A raw material supply apparatus includes a supply portion supplying raw material and a gas for dispersing the raw material and contributing to a reaction into a flash smelting furnace, wherein the supply portion has a lance provided at an upper portion of a shaft that blows the gas so that the gas forms a spiral flow.
