The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore apply gravity separation. However, all kinds of Iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation. Herein, magnetic separation and flotation separation will be used.

Step 1: Wash the ore The original sand tin ore enters the cylinder washing machine through the loader for washing. (The content of cohesive soil in the ore is high, these cohesive soils enclose tin minerals and waste rock, making it impossible to separate and hindering the normal progress of gravity beneficiation process, so the ore must be washed.) step2: screen the ore The cylindrical ore washing machine is very effective for washing such clay-bearing ores. At the same time, the ore washing product can be sieved into two particle levels, particles larger than 8mm and particles smaller than 8mm. step3: crush the ore Particles larger than 8mm enter the fine crusher for crushing, so that the final particles are smaller than 8mm. Materials smaller than 8mm are transported to the silo by screw conveyor and mixed with the finely crushed materials. An automatic feeding device is set under the silo to evenly feed the materials into jig machine. step4:gravity separation As the core equipment of the re-selection process, the jig machine is used to separate cassiterite and waste rock, obtain high-purity cassiterite, and discard the waste rock . step5:dewater the ore The concentrate and tailings of the jig are discharged with a large amount of water, so the tailings need to be dehydrated, and the concentrate directly enters the concentrate pool and can be excavated after natural precipitation. We can also dehydrate the concentrate and tailings separately according to the customer's specific requirements.

[Introduction]: The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore is gravity separation. However, all kinds of iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation. Herein, magnetic separation and flotation separation will be used.

[Application]: Gravity separation is the traditional method for tungsten, tin and gold, especially placer gold and placer tin. It is also common in the application of rare metal placer ores(niobium, tantalum, titanium, zirconium and so on). It is also used for weak magnetic iron ore, manganese ore and chrome ore.

Put the 20~4mm ore into heavy medium cyclone to be selected. Then the ore will enter into the rod mill. After that, it will be preselected in jig. The tailings over 2mm will be abandoned, and the ore below 2mm will be put into shaking table.

After the bulk flotation, the concentrate will be fine grinded, then will be do the flotation separation of lead zinc ore. After that Lead antimony concentrates and zinc concentrates will be produced.

The tin pulp enter into 300mm hydrocyclone, then overflow to 125mm and 75mm hydrocyclone group to remove the fine mud. The sand setting will enter into the process of thickening, desulphurization by flotation, and then cassiterite flotation.

Tin is a typical metal inasmuch as it's extremely malleable, ductile, and readily forms a grayish protective oxide on its surface, but it's much weaker than metals such as iron so it's not used as a construction material. It has a relatively low melting point, but a relatively high boiling point, which means it's a liquid over a wide range of temperatures and can be usefully employed as such in a number of industrial processes.

Although we think of tin as an everyday material, it's actually much less common than comparable metals such as copper or zinc. In terms of abundance, tin is roughly halfway down the list of chemical elements: the 49th most common in Earth's rocky crust, existing in concentrations of about 2 parts per million (0.0002 percent). There are tin deposits right across the world, though most tin now comes from the southern hemisphereand chiefly from south-east Asia. The most important producer countries are now China, Indonesia, Peru, Bolivia, and Brazil.

In any tin ore productionline, crusher and grinding mill is basically co-existed. For different production rate, we use different crushing, grinding and auxiliary equipment to compose of production line in tin mining.Tin ore crushing production line is mainly composed of jaw crusher, ball mill, classifier, magnetic separator, flotation machine, thickener and drier, with feeder, lifter and conveyor as supplements. SBM can provide various tin ore crushing and grinding equipment for you. Our expert can help you design a professional tin production line with reasonable price and high efficient which production volume ranges from 40t to 1000t per hour. The tin production line which is designed by SBMs engineers has many advantages of high efficiency, low energy cost, high production capacity and economy and rationality.

We know that the hardness of tin ore is 3.75. Both impact crusher and cone crusher can be used in tin ore crushing production line as the medium-fine crusher. But cone crusher is much more favorable. Big tin ore lumps that dig out from the deposits are fed to the jaw crusher and then transported to the transfer station. Actually, to ensure the capacity and the performance of the whole tin ore crushing plant, our SBM engineers always recommend our customers using it in the crushing plant. When the tin ore aggregates pass through the cone crushers, they are to be crushed to about 0~40mm (output size depends on the customers requirements, it is adjustable). Then the subsequent vibrating screen will separate the qualified one from the crushed aggregates and belt conveyor will convey them to store pile sites. The oversize ones will be crushed again by the cone crushers.

For tin ore crushing, there is jaw crusher for primary crushing; cone crusher for medium crushing and short head cone crusher for fine crushing. For tin ore grinding, we can provide you with ball mill which is the most widely used and coal mill, Raymond mill, trapezium grinding mill, etc. Different equipment has different application. SBM manufacture different crusher and grinding mill which has widely application.

Jaw crusher is used as Primary crushers and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 MPa. It is widely used both domestic and abroad in metallurgy, architecture, rock crushing, chemistry and silicate industry.

Cone crushers is used to crush all kinds of ores and rocks with medium hardness or above-medium hardness in many industries, such as metallurgy, construction, road, chemical and silicate industries. It is very suitable for intermediate crushing and fine crushing of ores and rocks.

formation of tin ore deposits: a reassessment - sciencedirect

formation of tin ore deposits: a reassessment - sciencedirect

Tin granites display advanced degree of fractionationTin granites are of ilmenite series (reduced), irrespective of S-, I-, or A-type affinityHydrothermal tin solubility is optimal under reducing and highly saline conditionsHydrothermal tin ore formation requires oxidation, fluid mixing, cooling

About 85% of all historically mined tin of about 27 million tonnes Sn is from a few tin ore provinces within larger granite belts. These are, in decreasing importance, Southeast Asia (Indonesia, Malaysia, Thailand, Myanmar), South China, the Central Andes (Bolivia, southern Peru) and Cornwall, UK. Primary tin ore deposits are part of magmatic-hydrothermal systems invariably related to late granite phases (tin granites, pegmatites, tin porphyries), and may become dispersed by exogenic processes and then eventually form placer deposits within a few km from their primary source, due to the density of cassiterite, its hardness and chemical stability. Alluvial placer deposits were usually the starting point for tin mining, and have provided at least half of all tin mined. The small-volume and late granite phases in spatial, temporal and chemical relationship to tin ore deposits are highly fractionated. Systematic element distribution patterns in these granite phases and their associated much larger multiphase granite systems suggest fractional crystallization as the main petrogenetic process controlling magmatic evolution and magmatic tin enrichment. Oxidation state controls the bulk tin distribution coefficient, with low oxidation state favoring incompatible behavior of divalent tin. Low oxidation state is also mineralogically expressed by accessory ilmenite (FeO TiO2) as opposed to accessory magnetite (FeO Fe2O3) in more oxidized melt systems. This difference in the accessory mineralogy and hence metallogenic potential (tin-bearing ilmenite-series versus barren magnetite-series granites), can be easily detected in the field by a hand-held magnetic susceptibility meter. The hydrothermal system is a continuation of the magmatic evolution trend and necessary consequence of the crystallization of a hydrous melt. The exsolved highly saline aqueous fluid phase, enriched in boron and/or fluorine plus a wide metal spectrum, can be accomodated and stored by the intergranular space in crystallized melt portions, or accumulate in larger physical domains, accompanied by focused release of mechanical energy (brecciation, vein formation), dependent on emplacement depth (pressure). The hydrothermal mobility of tin is largely as Sn2+-chloride complexes; the precipitation of tin as cassiterite involves oxidation. Tin typically characterizes the inner high-temperature part of much larger km-sized zoned magmatic-hydrothermal systems with the chemical signature Sn-W-Cu-As-Bi in the inner part (greisen, vein/stockwork/breccia systems, skarn) and a broader halo with vein- or replacement-style Pb-Zn-Ag-Sb-Au-U mineralization of lower temperature. This zoning pattern may also occur telescoped on each other. Active continental margins are the favorable site for both copper (gold) and tin (tungsten) systems. However, the narrowly segmented metal endowment and the episodic nature of ore formation suggest additional controls. These are the build-up of a subduction-derived metal and fluid inventory in the lower continental crust by flat-slab subduction (very little magmatism) for coppergold in the main arc, followed by large-scale intracrustal melting during mantle upwelling in the back arc for tin (chemically reduced reservoir rocks) and/or tungsten mineralization (less sensitive to oxidation state).
