Studies on the depressive action of chromate and dichromate salts on galena
1970
In the course of the experimental work conducted it was found that when galena was treated with chromate salts or dichromate salts in an aqueous solution, lead chromate identified by infrared spectroscopy was the main species adsorbed on the galena surface. The formation of chromium hydroxide or chromium oxide was not observed. Thermodynamic considerations of the Pb-Cr-S-H₂0 bulk system indicate the very stable character of lead chromate as shown in the potential-pH diagram constructed in this
