Visualizing Global Gold Production By Country In 2020

Aug 16, 2021 But before gold makes it into jewelry and vaults, it goes through a long and difficult production process that begins with mining. The price of gold broke an all-time high of 2,000oz in 2020, giving miners a brief boost to profitability. However, mine shutdowns due to the pandemic ultimately dented global gold production relative to 2019.
