tin beneficiation plant

Tin ore dressing plant density is larger than mineral association, as a result, for re-election method tin ore dressing technology is generally adopted. However, due to there are all kinds of iron oxide minerals exist in the minerals, such as magnetite and hematite, these minerals such as gravity separation or flotation are cannot be separated from tin ore dressing plant is very good, so, also can use magnetic separation or flotation tin beneficiation plant operation, etc. Gravity separation method is processing of tungsten, tin, gold ore, especially the processing placer gold, tin ore in the traditional method. In dealing with rare earth metals (niobium, tantalum, titanium, zirconium, etc.) in the sands of application are also common. Gravity separation was used for separating weakly magnetic iron ore, manganese ore, chrome ore.

Also known as dolomite, kaolin is a kind of common clay minerals in nature. Kaolin is a manufacturer of white pigment useful minerals, white degree is a major performance parameters affect the value of the kaolin. And kaolin often contain harmful impurities such as iron, organic matter, dark matter, these harmful impurities will make the kaolin presents different color, affecting the white degree. So before using kaolin must remove the impurities.

Gravity separation method is mainly the density coltan ore processing difference between using gangue mineral and kaolin, will light organic titanium, quartz, feldspar and iron manganese elements such as high impurity removal, thus reduce the influence of impurities of dialogue. Usually adopt the centrifugal separator to remove the high density impurities. Can also use the hydrocyclone group to finish sorting kaolin washing and screening in the process of operation, not only can realize the purpose of washing and grading, also can remove part of the impurities, has the very good application value. But re-election method meets the requirements of kaolin products are hard to come by, finally still have to through the magnetic separation, flotation and calcination method so as to obtain the qualified products.

Almost all of kaolin ore contains a small amount of iron ore, are generally 0.5% 3%, mainly include magnetite, ilmenite, siderite and pyrite colored impurities. Magnetic separation method is mainly by using gangue mineral and magnetic differences between kaolin, remove the colored impurities. For strong magnetic minerals such as magnetite, ilmenite or processed with iron filings, in the process of using magnetic separation method don't kaolin is more effective. For weak magnetic minerals, there are two main methods: one is to roast, make it become a strong magnetic iron oxide minerals, then carries on the magnetic separation; Another way is to use high gradient magnetic field magnetic separation method for magnetic separation. Due to the magnetic separation method does not need to Portable gold trommel use chemicals, basic won't cause pollution to the environment, thus is widely used in the process of non-metallic mineral processing. Magnetic separation method that caused by high iron content of commercial exploitation value does not have the problem of the development and utilization of Carbon in Pulp low grade kaolin has been effectively solved, superconducting magnetic separation machine has the characteristics of high field strength, energy saving, productivity, can directly handle more kaolinite containing impurities.
