 · Tin has been identified as a critical and strategic mineral in the Draft List of critical minerals by the USGS. Tin has a primary appliion for solder as well as flatpanel displays (indiumtinoxide), where the top producer is China and the top supplier is Peru ( Geological Survey, 2018). While tin is present in greisen, pegmatite, placer, and skarn deposits in the United States, the ...
