as i need rh to make plating solution, i get some extra rh(0,26 grams per kilo -average) doing the following:after doing the normal leach with hcl-cl or ar,i take the almost spent cat powder and put it in an h2so4(60%) solution+0,1mole nacl and boil for1,30hour----add slowly water to the cold solution ,filtate and then cement the rh with iron or zinc-------
this action proves that there is more rh in cats then indicated by manufactures-----if i leach 100kilos of cats,i obtain 26 to 30grams extra rh----makes 15 plating solutions which pays for all the cats bought
i am passing this information and would like to ask if one knows another way of obtaining an extra rh from cats
