Abstract:
A method of producing trona suitable for flue gas desulfurization comprising mechanically mining a trona ore deposit containing insoluble impurities; crushing the mined trona ore to create a mixture of uncalcined trona-rich particles and impurities-rich particles; beneficiating the crushed uncalcined trona ore to obtain a trona-rich, impurities-depleted ore fraction; and drying the trona-rich ore fraction under non-calcining conditions to yield a dry uncalcined trona ore. A preferred embodiment includes concurrently milling and drying the trona-rich, impurities-depleted ore fraction to recover a low moisture content trona product having a high NaHCO3:Na2CO3 ratio, useful for the efficient dry injection desulfurization of flue gas streams.
