Where can i buy hydrochloric acid & nitric acid used for gold refining?
i was told that i could make nitric acid by mixing 1qt sulfuric acid +1/2 cup sodium nitrate. i am new to refining and need all the info i can find. i am guessing that i can buy hydrochloric at an auto parts store because i think it is used in car batteries. but i want to buy the acids/chemicals already made to make it as easy as possible during my first few attempts at refining. i have pounds of computer pins and broken jewelry and want to get started asap. if anyone has any info on the aqua regia method of refining i would love to have it. i also am interested in platinum refining if you have any info. i am going to try catalytic converters as i have 8 to experiment on.
