Copper-lead-zinc ores can be divided into sulfide ores and oxidized ores, and oxidized ores can be divided into oxidized ores and mixed ores according to the degree of oxidation. Mixed flotation and concentrate regrinding process is adopted in the process, which can reduce the cost of grinding and is easy to manage. At the same time, new non-toxic flotation reagents are applied, which is
Feb 20, 2020 · The mixed froth flotation process lead and zinc sulfide ore are to float the mixed concentrate of lead and zinc sulfide first, and then separate …
Sulfide lead ore process divides into priority flotation process , mix-separating flotation , asynchronous flotation ,and so on . Application. The lead zinc ore procesing mainly deals with lead zinc sulfide and oxide ores with close intergrowth, uneasy dissociation and uneven particle size distribution. Features. 1.Preferred flotation
Sep 09, 2020 · The lead-zinc oxide and the gangue minerals are intricately inlaid, intersecting each other. During the flotation process of lead-zinc oxide ore, sulfides should be added to sulfide the minerals to facilitate the subsequent flotation treatment. The following issues need to be paid attention to during the sulfidation treatment of lead oxide ore: First, white lead ore, lead alum and molybdenum lead ore are easier to sulfide
In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, it’s a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents
Jul 09, 2019 · 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite
lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic. Get Price
Sulfide ore coarse raw body stronger collectors than it used to be able to get better than xanthate separation efficiency, copper and lead sulfide ore sorting. 3.Black medicine. The black drug sulfide ore effective collector, the collector than xanthate weak dialkyl dithiophosphate of the same metal ion solubility product than that of the
The flotation method is usually used for sulfide ore. Oxidized ores are beneficiated by flotation separation or combined gravity-flotation separation. For lead-zinc ores containing multiple metals, combined magnetic-floatation separation, gravity-floatation separation, gravity-magnetic-floatation separation, etc. are generally used
