Copper Market heading for a severe supply shortage
Mar 12, 2021· 2021.03.12. Mainstream media and the large mining companies are finally catching on to what we at AOTH have been saying for the past two years: the copper market is heading for a severe supply shortage due to a perfect storm of under-exploration/ lack of discovery of new deposits, clashing with a huge increase in demand due to electrification andRio Tinto - Kennecott Utah Copper Smelter,Ore concentrate (roughly 27% copper content) is the primary feed material for the FS furnace wherein it is smelted into Matte Copper (68% to 70% copper) and S-Slag waste material.
