GENERAL KNOWLEDGE

Detailed explanation-1: -In any case, it is clearly attested in the Assyrian texts from their trading stations in Anatolia that the Assyrians traded in tin and textiles in exchange for silver and gold with the indige-nous population of Anatolia during the Kültepe-Kanesh period c. 1920–1750 BC.

Detailed explanation-2: -The only mineral of commercial importance as a source of tin is cassiterite (SnO2), although small quantities of tin are recovered from complex sulfides such as stannite, cylindrite, franckeite, canfieldite, and teallite. Most tin is used as a protective coating or as an alloy with other metals such as lead or zinc.
