Tin minerals

Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite was the chief tin ore throughout ancient history and remains the most important source of tin today.

Stannite is a mineral, a sulfide of copper, iron, and tin, in the category of thiostannates.

Abhurite is a mineral of tin, oxygen, hydrogen, and chlorine with the formula Sn21O6(OH)14Cl16 or Sn3O(OH)2Cl2. It is named after its type locality, a shipwreck with tin ingots at Sharm Abhur, a cove near Jeddah in the Red Sea. Abhurite forms alongside other tin minerals like romarchite and cassiterite. Abhurite can vary in color, from pale green/yellow to darker brown/green.

Teallite is a sulfide mineral of tin and lead with chemical formula: PbSnS2. It occurs in hydrothermal veins and is sometimes mined as an ore of tin. Teallite forms soft silvery grey mica-like plates and crystallizes in the orthorhombic system. The Mohs hardness is 1.5 to 2 and the specific gravity is 6.4.

Kësterite is a sulfide mineral with a chemical formula of . In its lattice structure, zinc and iron atoms share the same lattice sites. Kesterite is the zinc-rich variety whereas the zinc-poor form is called ferrokesterite or stannite. Owing to their similarity, kesterite is sometimes called isostannite. The synthetic form of kesterite is abbreviated as CZTS (from copper-zinc-tin sulfide). The name kesterite is sometimes extended to include this synthetic material and also CZTSe, which contains selenium instead of sulfur. Along with perovskite, recent advances have made kesterite promising mat

Cylindrite is a sulfosalt mineral containing tin, lead, antimony and iron with formula: Pb3Sn4FeSb2S14. It forms triclinic pinacoidal crystals which often occur as tubes or cylinders which are in fact rolled sheets. It has a black to lead grey metallic colour with a Mohs hardness of 2 to 3 and a specific gravity of 5.4.

Franckeite, chemical formula Pb5Sn3Sb2S14, belongs to a family of complex sulfide minerals. Franckeite is a sulfosalt. It is closely related to cylindrite.

Canfieldite is a rare silver tin sulfide mineral with formula: Ag8SnS6. The mineral typically contains variable amounts of germanium substitution in the tin site and tellurium in the sulfur site. There is a complete series between canfieldite and its germanium analogue, argyrodite. It forms black orthorhombic crystals which often appear to be cubic in form due to twinning. The most typical form is as botryoidal rounded grape-like masses. Its Mohs hardness is 2.5 and the specific gravity is 6.28. Canfieldite exhibits conchoidal fracturing and no cleavage.

Tusionite is a rare colorless to transparent to translucent yellow brown trigonal borate mineral with chemical formula: MnSn(BO3)2. The mineral is composed of 18.86% manganese, 40.76% tin, 7.42% boron, and 32.96% oxygen. It is a late stage hydrothermal mineral and occurs rarely in granite pegmatites in miarolitic cavities.

thumb|Asbecasite found at its type locality Asbecasite is a calcium titanium beryllium arsenite silicate mineral with the chemical formula . Its type locality is the Binn valley in Switzerland.

Malayaite is a calcium tin silicate mineral with formula CaSnOSiO4. It is a member of the titanite group.

Hemusite (IMA symbol: Hm) is a very rare isometric gray mineral containing copper, molybdenum, sulfur, and tin with chemical formula Cu6SnMoS8.

Mohite is a copper tin sulfide mineral with the chemical formula Cu2SnS3. It is colored greenish gray and leaves a gray streak. It is opaque and has metallic luster. Its crystal system is triclinic pedial. It is rated 4 on the Mohs Scale and has a specific gravity of 4.86.

Kuramite is a mineral of the stannite group. It is named after the Kochbulak Au-Ag-Te deposit locality in the Chatkal-Kuraminskii Mountains in Uzbekistan, where it was first discovered.

Pabstite is a barium tin titanium silicate mineral that is found in contact metamorphosed limestone. It belongs to the benitoite group of minerals. The chemical formula of pabstite is . It is found in Santa Cruz, California. The crystal system of the mineral is hexagonal.

Genplesite is a very rare tin mineral coming from the Oktyabr'skoe deposit in the Noril'sk area, Russia, which is known for nickel and platinum group elements minerals. Its chemical formula is Ca3Sn(SO4)2(OH)6•3H2O. Genplesite is a member of the fleischerite group, and it is a calcium and tin-analogue of fleischerite. It is hexagonal, with space group P63/mmc.

Ferronigerite-2N1S is an iron, tin, alumino-hydroxide mineral that naturally occurs around sillimanite-quartz veins. Ferronigerite-2N1S belongs to the nigerite group, högbomite supergroup. The other constituents of the nigerite group are ferronigerite-6N6S, magnesionigerite-2N1S, magnesionigerite-6N6S, zinconigerite-2N1S and zinconigerite-6N6S. The 2N1S ending stands for the nolanite and spinel structural layers.
