Going by what I have learned in other places, I know that some of the content of the ore is likely to be iron. So it is recommended that I "wash" the crushed ore in hydrochloric acid first. Having done this I noticed that I did wind up with a dramatic change in the color of the hydrochloric (actually it was Muriatic) acid to that bright yellow described on another site...which was referred to as iron chloride. I have found sellers of iron chloride, however they characterize the substance as a powder. So now I am wondering exactly how I create a powder, and considering the process I delineated previously in this post...I am rather sure a powder is what is needed. Next in the line of curiosities is the Ammonia Hydroxide. Since I believe that household Ammonia, when heated will release the Ammonia gas at a much lower temperature than the water, couldn't I condense that Ammonia gas and mix it into distilled water to create an appropriately saturated solution of, or...Ammonia Hydroxide?

So heating Ammonia and bubbling the gas through water will make Ammonia Hydroxide? That sounds easy, but how do you know when saturated solution is achieved...ammonia smell or bubbles reach the surface? If that process is correct, is it a matter of pressure that forces the Ammonia gas into solution? I wrote all that and then realized something...is household ammonia just ammonia and water? If not, what is the difference?

The question is probably quite simple for those who know chemistry on a more personal level, I do not. I have this process... Preliminary treatment of the ore or base metal byproduct with aqua regia (a mixture of hydrochloric acid, HCl, and nitric acid, HNO3) gives a solution containing complexes of gold and palladium as well as H2PtCl6. The gold is removed from this solution as a precipitate by treatment with iron chloride (FeCl2). The platinum is precipitated out as impure (NH4)2PtCl6 on treatment with NH4Cl, leaving H2PdCl4 in solution. The (NH4)2PtCl6 is burned to leave an impure platinum sponge. This can be purified by redissolving in aqua regia, removal of rhodium and iridium impurities by treatment of the solution with sdoium bromate, and precipitation of pure (NH4)2PtCl6 by treatment with ammonium hydroxide, NH4OH. This yields platinum metal by burning. what I would like to know is: How can I make iron chloride (FeCl2)? How can I make ammonium hydroxide (NH3OH) ...or should I just buy them... I would also appreciate any suggested simpler methods of extracting the gold and platinum...if possible.

I noted several references to FeCl3 but none to FeCl2. I have a need for FeCl2 and have no idea how to synthesize it, if it differs from that already mentioned...which from what I gathered does not create FeCL2. Frankly I have no idea what the difference is other than that mentioned already which I don't readily assimilate. My purpose is the precipitation of gold from AquaRegia, which according to the process I have found requires FeCl2.
