A Brief History of Metals | SpringerLink
There are usually eight metals identified in antiquity: copper, gold, silver, tin, and iron as discussed, along with zinc, lead, and mercury. These metals were easy to recover from sulfide minerals by smelting as a consequence of the low melting points of zinc and lead.
Tin Statistics and Information | U.S. Geological Survey
Nearly every continent has an important tin-mining country. Tin is a relatively scarce element with an abundance in the earth's crust of about 2 parts per million (ppm), compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead. Most of the world's tin is produced from placer deposits; at least one-half comes from Southeast Asia.
