Gold extraction machine; Lead zinc extraction Use physical and chemical properties differences of mineral surface in the mineral particles sorting process, formerly known as method of flotation, which is the most widely used method of mineral processing. Almost all the ore can use the method of flotation, such as Gold, Silver Mine, galena, sphalerite, chalcopyrite, copper-fai, molybdenite, nickel sulfide minerals; Such as pyrite, malachite, white lead, zinc Ling, hemimorphite and mine Hematite, cassiterite, wolframite, ilmenite, Beryl, spodumene, and rare earth minerals, uranium ore and other minerals of the sorting; Graphite, sulfur, diamonds, quartz, mica, feldspar and other non-metallic minerals and silicate minerals and fluorite, apatite, barite, and other non-metallic mineral salts and potassium salt, rock salt and other mineral salts. Another important purpose of the flotation is to reduce the fine coal ash from coal and to remove fine-grained pyrite. With flotation processing more symbiotic metal minerals, such as from copper, lead, zinc, and other metal ores separate copper, lead, zinc and pyrite, and other concentrate, and can reach a very high sorting indicators.
