How Much G Has Been Mined? World G Council

Each , global g mining adds approximately 2,5003, tonnes to the overall aboveground stock of g. While g production has shown an upward trend in recent s, this is likely to level off in coming s. Accurately estimating the amount of g still within the ground is no easy task, and this estimate may change in response to several factors, such as
