Fig. 18From: Intermobility of barium, strontium, and lead in chloride and sulfate leach solutionsNanoSIMS images of baryte in leached concentrate sample 05CLD 13 from Olympic Dam. The estimated reaction front is marked in red. The non-correlation between 206Pb and 210Pb indicate multiple pathways; coeval incorporation of old lead into the baryte, uptake of 210Pb by the baryte during acid-leaching, and decay of 210Pb from 226Ra previously taken in by the baryteBack to article page
