Fig. 11. Activity ratio/product diagrams showing the relative stability of Pb-bearing minerals as a functions of pH, H2PO–4
activity, Pb2+(aq) activity, and CO2(g) partial pressure at 35°C and 1 atm (0.1 MPa) total pressure (other conditions specific to the generation of the diagrams are discussed in the text). ALA, alamosite; CER, cerussite; CPM, chloropyromorphite; DCDP, brushite; HCER, hydrocerussite; HAP, hydroxyapatite; HPM, hydroxypyromorphite; and PGM, plumbogummite.
