Mercury is mainly used in scientific instruments.The graph below shows the mercury extraction data for the world and two Verhulst function fits to the data in order to extrapolate into the future.
Mercury extraction rate for the world and a Verhulst function fit to the data.
The red curve is a fitted with total amount to be extracted of 1000x10^3 tonnes and the blue curve is for a fit with two Verhulst functions. It appears that mercury is highly depleted.
