  • Patent number: 10144988
    Abstract: A rotation-suspension smelting method, in which a powdered sulfide concentrate and an oxygen-containing gas are sprayed into a high-temperature reaction tower. The oxygen-containing gas is divided into two parts: the second oxygen-containing gas is sprayed in the form of an annular direct flow into the reaction tower and forms a bell-shaped wind curtain; and the first oxygen-containing gas is transformed into a rotation-jet and jetted into the center of the wind curtain. In the space between the gas flows, the concentrate entering in a direction deviated towards the center is drawn in the rotation-jet, and a high-temperature off-gas is sucked in, forming a gas-particle mixed two-phase rotation-jet. The sulfide concentrate is ignited, at the same time, a melt containing matte (or metal) and slag is formed; and the matte (or metal) is separated from the slag at the bottom of the reaction tower, completing the metallurgical process.
