These deposits are rare compared with the other deposit types already discussed. They have produced significant amounts of zinc, lead, silver and sometimes copper. But, most of them are not economical to mine. Figure 9.90 shows copper ore (mostly chalcopyrite and bornite) from the Rammelsberg SEDEX deposit in Germany.

Lead-Zinc Ore Processing Equipment. The lead-zinc ore flotation process often involves several stages, including: Gravity Beneficiation: This method is usually the initial step, especially for galena (a lead sulfide mineral) which has a coarse embedded particle size. Simple crushing followed by gravity beneficiation using a jigger can yield the ...

Abstract The article describes the studies on the material constitution of two lead–zinc ore samples from the Gorevka deposit. The samples are difficult ore because of fine dissemination of galena and its complex intergrowth with sphalerite; feature partial replacement of lead sulfide by anglesite and cerussite; contain colloform galena. The …
