Jul 30, 2009· How effective is butyl diglyme for extracting gold out of aqua regia? Does it react badly (explosively) with nitric acid? I've used diethyl ether on aqua regia before, and it appears semi-dangerous and somehow effective. I let the aqua regia extract magnetite for a day, then add an equal amount of ether, mix, and decant the ether. Three times.
Pure metals, i.e. platinum, palladium and gold, were dissolved in aqua-regia and diluted to 2000 ppm (as metal) in 4M HCl. Ruthenium, rhodium and iridium were dissolved from pure salts in HCl.
Aug 27, 2017 n-octanol/MIBK mix is probably the best (solubility wise) but does need a diluent due to viscosity and is not oxidatively stable so it's in HCl systems with ORPs less than 650 mV. You can use TBP in aqua regia, butyl diglyme as well (in diluted AR). Of course, wise people going for recovery use resins for gold extraction and elution.
Sep 23, 2008· Reverse electroplating for environment-friendly gold recovery / refining 2001. Q. I am about to embark on scrap circuit board recycling, primarily for the gold and platinum content.
