In this edition of "Conflict Minerals Compliance Basics," we will give the derivatives of tin, tantalum, tungsten and gold.
| Conflict Mineral | Derivative Metal | Trade |
| Tin | Cassiterite | Tin Cassiterite Tetrabutyltin starting material for the di- and tributyl compounds. Tributyltin oxide, a colorless to pale yellow liquid used in wood preservation. Triphenyltin acetate, an off-white crystalline solid, used as an insecticide and a fungicide. Triphenyltin chloride, a white crystalline solid, used as a biocide and an intermediate in chemical synthesis. Trimethyltin chloride also a biocide. Triphenyltin hydroxide, an off-white powder, used as a fungicide and to sterilize insects. Azocyclotin, a colorless crystalline solid, used as a long-acting acaricide for control of spider mites on plants. Cyhexatin, a white crystalline solid, used as an acaricide and miticide. Hexamethylditin used as an intermediate in chemical synthesis. |
| Tantalum | Tantalum Columbite | Tantalum Columbite-tantalite Tantalum oxide is employed in making optical glass and has piezoelectric, maser, and laser applications. Tantalum alcoholate is used as a catalyst, intermediate for pure tantalates, preparing thin dielectric films. Tantalum carbide is used in cutting tools and dies, cemented carbide tools. Tantalum(V) chloride is used in chlorination of organic substances, intermediate, production of pure metal. Tantalum fluoride is used as a catalyst in organic reactions. Tantalum disulfide is used as a solid lubricant. Tantalum carbide is used as an abrasive. Tantalum salts is used in paint and dye industry, in glass and ceramic industry. Tantalum oxide is used to make special glass with high index of refraction for camera lenses. |
| Tungsten | Wolframite | Tungsten Wolframite Tungsten Carbide is used in metalworking, mining, cutting tools bits, heat- and erosion-resistant parts, coatings, seal rings and petroleum. Calcium and magnesium tungstates are widely used in fluorescent lighting. Tungsten salts are used in tanning industries. Tungsten disulphide is used as a dry high temperature lubricant (stable to 500°C). Tungsten bronzes and other compounds are used as pigments for paints. |
| Gold | Gold | Gold Gold Potassium dicyanoaurate, K[Au(CN)2], used in gold electroplating baths. Chloroauric acid, HAuCl4, used as an intermediate in the production of other gold compounds and occasionally for colouring ceramics. Gold salts are also used as anti-inflammatory drugs in the treatment of rheumatoid arthritis. |
