The Economics of Copper Demand, Supply and Options

02/03/2021 Many mines in Chile, which accounts for 28% of global copper supply, closed for at least part of 2020 as a result of COVID-19. This led to a 3.7% dip in copper production globally during the second quarter of 2020. For the year, copper production fell by approximately 1.5% from 2019. Just as demand for copper-intensive manufactured goods and housing was picking up, copper supply was

Economic Impact Copper

Copper mining is controversial because it adds a great deal to the economy, while also striping the land of its resources, and leaving a wake of poor poverty and ill health. Because of the danger, high wages, and frequent layoffs many mining towns see very high unemployment rates. Overall, mining

Gangue from copper mining typically contains silicate minerals and oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock.
