Abstract
The invention uses evaporites, e.g., from dried prehistoric lake beds to sequester carbon. The invention provides a method of sequestering carbon comprising: (a) dissolving crude naturally formed evaporites in water to form dissolved evaporite cations and anions; (b) contacting aqueous dissolved carbonate or bicarbonate, formed by dissolving carbon dioxide in water, with the dissolved evaporite cations to form precipitated carbonate mineral; and (c) sequestering the precipitated carbonate or bicarbonate mineral.
