Abstract: PURPOSE: Provided is a hydrometallurgical zinc production process by which zinc and other valuable metal elements such as lead, gold and silver, as well as the by-product elemental sulfur are recovered from zinc concentrates which are sulfides containing not only zinc but also other valuable metal elements such as lead, gold and silver. CONSTITUTION: In one method, a zinc concentrate is leached as elemental sulfur and other by-products are stripped from the surfaces of the particles in the concentrate by means of a grinding machine such as a ball mill. The ferric ion consumed by leaching is regenerated for recycled use by introducing oxygen into the post-leaching solution flowing through feed pipes(2). This method can shorten the leach time by a substantial degree. In another leaching method, a solution containing free sulfuric acid and ferrous ions and a zinc concentrate are charged into an autoclave having a pressurized atmosphere and as oxygen gas is supplied, the internal temperature is adjusted between 90 deg.C and 120 deg.C, whereby the ferrous ion in the solution is oxidized to increase the ferric ion concentration to 2-60 g/L whereas pressurized leaching of the zinc concentrate is performed simultaneously. Following this one-step oxidative leaching process, the resulting slurry is subjected to a grinding/leaching step in which by-product elemental sulfur is stripped from the surfaces of the particles in the leached zinc concentrate and, thereafter, the slurry from the grinding/leaching step is subjected to another pressurized leaching step.
