摘要:【中文】本发明公开了一种锌浸出渣的制粒方法与锌浸出渣物料及其应用,其中,所述锌浸出渣的制粒方法包括:获取锌浸出渣;将所述锌浸出渣与石灰混合,得到混合物料;将所述混合物料进行堆存;将堆存后的混合物料与燃料混合得到配入燃料的混合料,再向所述配入燃料的混合料中混入次氧化锌粉进行制粒,完成锌浸出渣的制粒。本发明提供浸出渣的制粒方法无需采用干燥窑对浸出渣进行干燥,即可使制粒前的物料的水分满足制粒系统的要求,解决现有技术中需采用干燥窑对锌浸出渣进行干燥导致的投资及运行成本较大的问题。 【EN】The invention discloses a zinc leaching residue granulating method, a zinc leaching residue material and application thereof, wherein the zinc leaching residue granulating method comprises the following steps: obtaining zinc leaching residues; mixing the zinc leaching residues with lime to obtain a mixed material; stacking the mixed materials; and mixing the stacked mixed materials with fuel to obtain a fuel-blended mixture, and then mixing secondary zinc oxide powder into the fuel-blended mixture for granulation to complete the granulation of zinc leaching residues. The method for granulating the leaching slag provided by the invention can ensure that the moisture of the material before granulation meets the requirement of a granulating system without drying the leaching slag by adopting a drying kiln, and solves the problem of higher investment and operation cost caused by the fact that the zinc leaching slag needs to be dried by adopting the drying kiln in the prior art.
