2019-12-16 · At present, flotation is a common method for extracting lead-zinc-copper associated silver ore. According to the process conditions and chemical system of the main metal, it is advisable not to extract the single silver concentrate. The common extraction process is to enrich silver into lead, zinc, and copper concentrates, and then extract

It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates

The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for

This study investigated the flotation performance, structure-activity relationship and adsorption mechanism of a newly-synthesized collector N-ethyl-N'-isopropoxycarbonyl thiourea (EICTU) for copper sulfide minerals in Gacun polymetallic ore. The bench-scale flotation test indicated that EICTU exhibited superior flotation performance to the copper sulfide minerals compared with conventional
