A method comprising:
- pumping a mercury product solution into a disposal well, wherein the disposal well is classified as a United States Environmental Protection Agency (EPA) Class I Industrial and Municipal Waste Disposal Well.
A method comprising:
- reacting an acid and elemental mercury and/or a mercury-containing compound in a reaction vessel to form a mercury product solution;
- withdrawing a first portion of the mercury product solution from the reaction vessel leaving a second portion of the mercury product solution in the reaction vessel;
- and
- introducing an additional volume of the acid and the elemental mercury and/or the mercury-containing compound into the reaction vessel and reacting the additional volume of the acid and the elemental mercury and/or the mercury-containing compound in the presence of the second portion of the mercury product solution to produce an additional volume of the mercury product solution.
