Abstract

The invention discloses a beneficiation method for lead glance and other lead-containing sulfide materials and minerals, including ores, concentrates, tailings and other similar materials or wastes. These materials may be flotation products, filter cakes, ores, tailings, and the like. The process can be used to selectively separate lead components from other metal materials such as zinc, copper, nickel, cobalt, silver, gold, and the like.

Description

technical field [0001] The invention relates to the technical field of leaching lead sulfide, in particular to a method for selectively leaching lead sulfide from lead-containing sulfide materials Background technique [0002] One known beneficiation method is to use flotation to select target minerals. Priority flotation technology is used when the ore contains mixed minerals such as lead, copper, zinc, silver, gold, bismuth, antimony, etc. However, in some cases it is not possible to effectively separate the target metals and produce a single metal concentrate. Typical metal mixtures that are difficult to preferentially float include lead and copper, lead and copper zinc, lead and gold, and lead and zinc. [0003] Downstream processing of concentrates is designed to handle the main metal components, with additional metals adding complexity and incurring penalties or limited payments to the concentrate seller. Take zinc smelters as an example, lead processing requires se...
