Tin processing Britannica

Tin processing, preparation of the ore for use in various products. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is

Recycling - International Tin Association

The Recycling Input Rate (RIR) is a percentage of the contribution to this total of secondary tin, both in refined and unrefined forms, and in 2018 the RIR of tin was 31%, with re-refined tin contributing approximately 13% and the remainder reused or reformulated alloys. These rates have varied between 30-35% over the last decade, with dips ...
