World Gold Production and Consumption by Country

Sep 05, 2021Its gold mining industry is minuscule so almost all of its consumption is imported. The major use of gold is for jewelry and other ornamental uses. Gold is also seen as a storehouse of value. The United States consumes around 193 metric tons of gold per year. Consumption is mixed between industrial, investment, and jewelry use.
