摘要

1. The invention concerns a leaching method for oxidised zinciferous materials, particularly for roasted sphalerite, by means of sulfur acid solution, whereas the materials are supplied continuously by means of a worm conveyor, whereas in the tubular part of worm conveyor oxidised zinciferous materials are mixed with reverse electrolyte from zinc electrolysis while maintaining the ratio of oxidised zinciferous materials to reverse electrolyte preferably at 1:8 be volume and up to 90 percent of H2SO4 amount as necessary for dissolving zinc oxide comprised in leached zinciferous materials, and then the pulp so formed is directed to a passage tank where zinciferous materials and the sulfur acid and zinc sulfate are further mixed, and then from the passage tank, the pulp is collected and directed for further leaching, characterised in that roasted sheet zinc preferably in the form of mixture of roasted ore from grains and dusts is subject to conditioning at temperature preferably from 260 to 170 degrees Celsius for 2-4 hours in a closed space, and then the roasted ore from grains and dusts is subject to stirring in the worm conveyor if necessary, or the mixture of roasted ore from threshold and dusts is directed through the worm conveyor to a worm gear feeder, and finally to the tubular outlet where the roasted sphalerite is subject to leaching in a tubular head.IMAGE
