01 Magnetic-flotation-gravity separation process of zinc-tin polymetallic sulfide ore. Polymetallic sulfide ores generally contain iron minerals (such as magnetite) and sulfur minerals (such as pyrrhotite, pyrite). Therefore, iron-containing minerals and sulfur-containing minerals should be removed as much as possible before zinc and tin …
