hello all
I'm a newbie with refining. I have been reading so much info on the AR process for cats. It seems that all I can find is 4 parts hcl and 1 part nitric for making AR. That's the only info I can find. I don't no if roasting is necessary. If so how do I do that. Then what is next. Just drop the honeycomb or pellets in? So next the pt pd and rh are suspended in the AR? Then I would like to actually separate the pt pd and rh from eachother to make them pure. I cannot find out how to precipitate then all separate from one another. Basically I read for a couple months and found nothing. I really need a step by step process breakdown. I don't know where to find this. Please can someone point me in the right direction? Mainly the separation of the pgms from Eachother. I appreciate all your help.
Thanks again
Dave
P.s. Sorry for typos as I just spent a half hour typing on my phone.
