Zinc smelting short-flow leaching method

The invention belongs to the technical field of zinc smelting, and particularly relates to a zinc smelting short-flow leaching method. The zinc smelting short-flow leaching method specifically comprises the following steps: S1, neutral leaching is carried out on zinc smelting calcine, and high-temperature high-acid leaching is carried out on the underflow concentrated by a thickener to obtain high-acid ore pulp; S2, directly conveying the high-acid ore pulp to an iron settling reaction tank through an acid leaching storage tank pump to be subjected to spraying and iron settling; and S3, concentrating the ore pulp which is obtained through the treatment of spraying and iron settling in S2 by a thickener, and carrying out filter pressing on the underflow by a diaphragm box type filter pressto obtain zinc-containing leaching residues and filtrate. The zinc smelting short-flow leaching method combines the three-stage leaching of the secondary zinc oxide and the calcine high-acid leachingiron settling process into
