The method of construction of F zinc ore mineral concentration process delivered overseas re-election lead-zinc concentrator preselected as follows: 12-100 mm heavy media beneficiation level application under the gravitational field, 12-1.2 mm in diameter and 500 level Separated cyclone mm, medium consisting of ferrosilicon and magnetite 7.5: 92.5 ratio of the composition, the proportion of medium 2.40-2.46 kg / liter. Heavy media beneficiation was 29% light products, heavy products is 96-99% metal recovery. For the high iron content of lead-zinc mine, if not effectively use flotation separation, you can deal with by magnetic separation. Magnetic separation method can be used to select zinc iron spinel from mixed concentrate, the de-iron from zinc concentrates, can get high-quality zinc concentrates. Flotation is the main processing methods polymetallic sulfide ore. Closely related to the flotation effect, using the processes and flotation process conditions and the mineral composition and structural characteristics of the processed ore. When lead-zinc ore contains only matter, the flotation process conditions and processes are relatively more simple. If in addition to lead-zinc composition, but also contains copper minerals, pyrite, precious metals and associated minerals other when they are sorting becomes more complicated. If the ore containing limonite, clay-like minerals, soluble heavy metal salts, graphite, carbonaceous shale and talc, this mineral flotation becomes more complicated. Ore structural features also have a significant impact on the flotation process. Uneven disseminated ore flotation stage must, useful minerals or uneven thickness was fine disseminated ore beneficiation process will cause difficulties on the sulfide minerals in particular were a mixture isomorphism exists, conventional processing methods They are inseparable and need to be recovered by chemical processing or smelting methods. Zhengzhou City, the construction of mining equipment factory is a professional production of mineral processing equipment manufacturers, device models to meet the needs of customers of different classes, and free for customers to do beneficiation tests, you only need to bring 20 kg sample to our factory, you can see dressing effect. Our professional and technical personnel for your design beneficiation process and is responsible for installation and commissioning of the equipment, so that the entire process for you.
