We present spectroscopic analysis of the broad absorption line outflow inquasar SDSS J1512+1119. In particular, we focus our attention on a kinematiccomponent in which we identify PV and SIV/SIV* absorption troughs. The shape ofthe unblended phosphorus doublet troughs and the three SIV/SIV* troughs allowus to obtain reliable column density measurements for these two ions.Photoionization modelling using these column densities and those of HeI*constrain the abundance of phosphorus to the range of 0.5-4 times the solarvalue. The total column density, ionization parameter and metalicity inferredfrom the PV and SIV column densities leads to large optical depth values forthe common transition observed in BAL outflows. We show that the true CIVoptical depth, is about 1000 times greater in the core of the absorptionprofile than the value deduced from its apparent optical depth.
