Effect of Lead Nitrate on Gold Leach Kinetics

Stibnite behaved in a manner similar to orpiment with the exception that a smaller amount of lead nitrate was required to correct the retarding effects of its decomposition products on gold dissolution This apparently was due to the slower decomposition of stibnite and the correspondingly smaller amounts of sulphide compounds formed...
