Tin

A relatively scarce element, tin is a soft silvery-white metal with high malleability and low melting point. It is highly rust-resistant as well as fatigue-resistant. Its abundance in the Earth’s crust stands at just 2 parts per million (ppm). This is comparatively low when related to 63 ppm for copper, 94 ppm for zinc, and 12 ppm for lead.

Tin ore exists as cassiterite (SnO₂), the only mineral that holds commercial significance as a source of tin. However, tin in small quantities is also found in canfieldite, stannite, teallite, cylindrite, franckeite and other complex sulphides.

Applications

There are a number of applications of this soft, white metal. Tin has a great property of forming alloys with other metals, which makes it apt for wide-scale industrial applications. The metal is widely used in the production of tinplate, or as coatings for steel containers to prevent corrosion. Tin and its alloys are used for making solders, for bearing metals and as metallic coatings. Inorganic compounds of tin, such as Tin (IV) oxide are used in glazes and ceramics.

Organic compounds of tin are utilised in making pesticides, wood preservatives, plastics, and fire retardants. Molten glass is floated on molten tin to produce a flat surface of window glasses. Also, tin salts are used as sprays onto glass for making coatings which are electrically conductive.

Global mine production and reserves

As per the latest United States Geological Survey (USGS 2025) data, China and Indonesia continue to dominate global tin mine production, with China remaining the largest producer, followed closely by Indonesia and Myanmar. Other notable producers include Peru, Bolivia, and Brazil, contributing to a diversified global supply base.

In terms of reserves, China and Indonesia hold significant tin reserves, along with Brazil, Bolivia, and Australia, which also possess substantial economically recoverable resources.

Globally, tin resources are widely distributed, with major concentrations in Southeast Asia, particularly Indonesia and Myanmar; South America, including Bolivia, Brazil, and Peru; Australia; China; and parts of Africa, supporting long-term supply potential for the metal.
