Tomas : I was able to garner some information from the referrenced article. It appears they use a nitric/sulfuric acid mix in a pressurized system to draw the precious metals out into solution and then remove the metals such as silver by electrowinning. No design was shown but at least this gives some idea of theory and operation.
