The tin ore washing-processing line can include washing, screening, gravity separation, milling, and floatation separation. And for different tin mine, different flow sheet can be designed according to the ore natures. There are cassiterite, stannite, multi-metals tin ore, and cylindrite ore in tin mineral catalogue, and different processing flow sheet shall be involved for different tin mineral.

The chemical composition of cassiterite is SnO2 with its tetragonal system of bi-taper, columnar, and sometimes needle-like. Its specific gravity is 6.3-6.5. As the main source of metal tin, cassiterite is kind of tin mineral with highest tin content. Most of tin in cassiterite is in shape of crystals with high single separation degree and big density, so gravity separation is a great enrichment way to get high-grade tin concentrate. For the cassiterite in alluvial tin ore, simple hand selection can help to get qualified concentrate, but it needs large human power with low efficiency. And that is why a tin ore washing production line is needed. The following is about a picture of raw tin ore:

As the picture shows, there is much stick clay in the alluvial tin ore and the main tin mineral is cassiterite. The upper pictures are about lumpy tin after washing by hands. When hand selection is used, only coarse tin can be get and the fine granules will be missing, so a mechanized tin ore processing line will be needed to enrich the fine, medium, coarse tin granules. And here is some tin dressing flow chart to share:

The loader will put the raw tin ore into the rotary washing machine to remove the sticky clay and liberate the tin granules from the packaged mud. This tin log washer can also screen the tin into -8mm and +8mm. The -8mm minerals go for 2LTC6109/8T jigger through vertical spiral conveyor while the +8mm ores will be put into crusher for crushing to be -8mm and the crushed -8mm tin ore will be conveyed to jigger for jigging separation. Tin jig concentrating machine is the core equipment in this gravity separation washing line to separate the tin concentrate from the impurities. There is a large quantity of water in tailings and concentrate, so dewatering screen can be used for the tailings while the concentrate can be discharged into the concentrate pool for further deposit. Dewatering processing can be designed according to requirements of clients. The following picture is about one of Forui tin mining separating site to share:

extraction of tin from its ore - jxsc machine

Rock Tin ore is one of the metals that mankind first discovered. In the early days, our ancestors innovative extraction of tin from its ore, used tin, copper and lead to produce bronzes. Tin and tin alloys have been widely used in modern national defense, modern industry, advanced science and technology and human life because of the ductility, stability of chemical properties, corrosion resistance and melting, small friction coefficient and non-toxic tin salt. Rock Tin ore has the characteristics of strong development, rust resistance and corrosion resistance. Rock Tin can form various alloys with other metals, is easy to be plated on many metal surfaces. In particular, the surface of tin is corrosion-resistant and nontoxic. Rock Tin ore is relatively concentrated in the world, mainly in Southeast Asia, Central South America and eastern Russia, followed by eastern Africa, Western Europe and western North America.

In nature, the tin ore are existing in sand or alluvial raw material, this kind tin ore called sand tin or alluvial tin, the raw material may be with stone, sand, gravel, soil, sticky clay, some times with other magnetic iron, tungsten, ilmenite, hematite, monazite, zircon sand and other minerals. The other type tin ore is hard rock tin ore, the tin is existing in hard rock, such as normal stone, quartz vein above the land. The rock tin ore is mostly like to be with tungsten ore together.

In general, the rock tin ore processing machine of heavy selection are generally used, and the ore dressing of tin ore with a high degree of dissociation of the monomer is basically the same as the ore dressing of gold ore, and the better ore dressing index can Be obtained by simple screening. For ore processing of tin ore with low dissociation degree, it is often necessary to break the secondary structure by bar grinding and other processes, so as to improve the recovery rate and concentrate grade. The basis of the gravitational separation of sand tin ore processing machine is also the principle of gravity separation. According to the specific gravity difference between tin ore and waste stone, the proportion of tin and waste stone in the tin deposit is very good And the beneficiation effect can be obtained by the method and equipment of heavy separation in tin ore processing plant. At the same time, the advanced tin ore processing plant has the advantages of high efficiency, energy saving, environmental protection and so on, the investment of equipment is small, and the operating cost is low. It is an ideal choice for the beneficiation of Sands. The equipment for gravity separation of sand tin ore is mainly jig. Sometimes, the rocking bed is also used to improve the recovery rate of finely grained tin ore. The technological process of gravity separation for sand tin ore is screening, jigging and dewatering. The sand tin ore with a low degree of dissociation, two reelection processes are often needed: screen jig, rod mill, jigging and dewatering.

Extraction of tin from its ore generally adopts gravity separation method, which is determined by the density of tin ore than the characteristics of paragenetic minerals. However, iron oxides such as magnetite and hematite are often associated with tin ores, so gravity separation is not possible. Therefore, magnetic separation and flotation methods will be used in tin ore dressing. Tin ore extraction process flow 1. Ore washing and desliming This step is aimed at raw materials with high mud content and strong cementation. Such raw materials must be washed and desliming before crushing. The mine washing machine is used for washing the ore, and the classifier is used for the desliming and the hydrocyclone. 2. Crushing and screening Using the jaw crusher and hammer crusher, the ore is broken into ore with a particle size below 20mm. Then the vibrating screen is divided into two particle sizes, 0-4mm and 4-20mm. Rock Tin Ore Crushing: for crushing the big rock tin ore stone to a smaller size before grinding. Crushers can be rough rock tin ore jaw crusher, rock tin fine jaw crusher, rock tin cone crusher, rock tin hammer crusher, roller crusher rock, depends on the rock tin ore feeding size and process capacity to use which kind crusher. Rock Tin ore Grinding: after crushing the stone to a smaller size, need to grind to power by tin ore ball mill grinding machine or wet pan mill or other rock grinding machine, so the tin concentrate can be released out from stone. Then go to the gold separation machine and concentration machine( tin ore shaking table). 3.Pre-selection stage After crushing and sieving, the ore of 4-20mm should be pre-processed by using heavy medium cyclone, and then into a grinding section. After grinding, jigs and vibrating screens are used for further separation. The screen is controlled at 2mm, 2mm and then the concentrate is selected by shaking table, +2mm becomes tailings. 4.Flotation process The flotation stage is divided into two steps: mixed flotation and separation flotation. Firstly, the concentrates selected by jig and shaking tables are mixed flotation, then the concentrates are separated by lead and zinc flotation, and the tailings are separated by shaking table. 5. Gravitational separation Slime enters the 300mm cyclone, then overflows through 125mm and 75mm hydrocyclones to remove fine mud, and then the sediment is concentrated and desulfurized by flotation and cassiterite flotation.

Introduction to tin mine The large productivity of the sand washing machine equipment can meet the requirements of the industry that requires the cleanliness of ore and stone. It can be used for the cleaning of mud-bearing ore before the beneficiation process is carried out, and the subsequent process beneficiation index is improved. It is often used in manganese ore, iron ore, limestone, Cleaning of minerals such as tungsten ore, tin ore, and silica sand. Before the beneficiation process, by cleaning the ore, it is possible to effectively avoid mud clogging equipment and screening equipment in the mud-containing mineral raw material, and at the same time, if the raw material contains such soluble components or harmful components, it is also washed in advance. One of the genetic types of tin deposits. According to its genesis, sand-tin deposits can be divided into residual sand deposits, slope sand deposits, karst cave sand deposits in limestone areas, alluvial sand deposits and coastal sand deposits. The distribution of alluvial sand-tin deposits is generally close to the original tin deposits, mostly in the range of 3 to 5 kilometers, rarely reaching 8 to 10 kilometers. The karst cave deposits in the limestone area are important. Tin ore washing equipment Sieve: It can be used with a circular sieve or a roller sieve. Sand washing and recycling machine: Through the sand washing and recycling machine, the washing, dehydration, and recovery of the material under the sieve after the sieve is obtained by the circular vibrating screen. Concentration tank: Separation of mud and water by concentration and sedimentation to achieve tail water purification.

Because the density of cassiterite is higher than that of symbiotic minerals, the traditional process of tin ore beneficiation is gravity beneficiation. With the passage of time, the particle size of cassiterite in the selected ore continues to become finer, and the cassiterite flotation process appears. In addition, because tin minerals often contain various iron oxide minerals, such as magnetite,
