Sustainable Production
A Balanced Tin Supply. World tin production has been quite stable in recent years, with refined tin production between roughly 330,000 tpy and 370,000 tpy. This is made up from mine production between 270,000 tpy and 310,000 tpy, and the balance by 50,000 – 70,000 tpy of secondary refined tin production.
