During the Chinese Spring festival, majority of mining machinery companies were taking a holiday, in this period, these companies business was very cold, but Hongxing Company is obviously contrary. During January, all kinds of secarropas, flotation machines, as well as cement equipment of our company present favourable sales momentum, sales personnel in each departement have exceeded the mandate issued months ago. A brief Introduction to the Ore Beneficiation Method. Flotation Separation The flotation separation is a mineral separation which depends on the difference of physical and chemical properties of mineral surface. Through the process of flotation agent, the useful mineral will selectively attach to the bubble, so that the purpose of separation can be achieved. The flotation separation is mainly used for the separation of non-ferrous metal ores, such as copper, lead, zinc, sulfur, molybdenum and so on. In addition, the flotation separation also can be used for the separation of some ferrous metals, rare metals and some non-metallic you pray, pray such as graphite, apatite, and so on. Gravity Separation The gravity separation is a mineral separation method which depends on the relative density (also named specific gravity) of ore. The mineral particles with different densities will suffer different University force and mechanical force in the moving medium (such as water, air and heavy liquid), which forms proper conditions for delamination and separation, so that the mineral particles with different densities can be separated. Magnetic Separation The magnetic separation is a mineral separation method which depends on the difference of mineral magnetism. In the magnetic field of magnetic separator, different minerals will suffer different acting force. This method is mainly used for the separation of ferrous metals (such as iron, manganese and chromium). It also can be used for the separation of non-ferrous ores and rare metal ores. The production line of the ore beneficiation has a wide application, therefore the economic profits brought about by it is gratifying. But one point should be kept in mind that no mining machinery is durable forever. In order to prolong its lifespan, the maintenance of it has become an extreme vital work each day. The experts in Hongxing would like to share their experience of the equipment as the ensuing, the maintenance and overhaul. First of all, the bearing in the equipment takes on the responsibility of the whole machine s load. Therefore, to a great extent whether it can be well lubricated can affect the running rate directamente. So we should attach great importance to the cleaning of the lubricating oil as well as the inner part of the facility itself. What s more, it should be well sealed. Second, try to avoid the collision of the machines with each other and make sure the equipment clean, never working with corrosive materials in the same environment. At last, the inspection and consolidation of the facility are necessary, you should check out the result and write it down, not only the former record, maintenance and modification but also the usage and workload of each day so as to analyze and identify machinery breakdown. Then you are able to eliminate the hidden danger promptly and precisely.
