Strontium and calcium coprecipitation with lead-bearing barite from hot spring water

Abstract

The amounts of strontium and calcium in the lead-bearing barite from hydrothermal solution were found to increase with the lead content of the barite. This fact suggests that the difference between DMPbSO4 = [M/Pb]PbSO4/[M/Pb]aq and DMBaSO4 = [M/Ba]Baso4/[M/Ba]aq primarily contributes to the increment of both trace elements in the barite, where DMPbSO4 and DMBaSO4 represent the distribution coefficients of M which refers to strontium or calcium; [M/Pb] and [M/Ba] indicate the M-lead and M-barium weight ratios, respectively, in sulfate and aqueous solution.
