It didn't seem like the the gold leaching effect was so good as it only dissolved a minor part of the gold in the ore. Enough to be worthwhile to recover but the majority went along with the copper concentrate to the smelter. For ram memory sticks, most of the gold is contained in the thin bond wires embedded in the plastic capsule.

The cyanide leaching process is one of the main gold processing methods, which can be divided into agitation cyanide leaching and percolation cyanide leaching. Among them, the agitation cyanide leaching process mainly includes the cyanidation-zinc replacement process (CCD method and CCF method) and unfiltered carbon cyanide slurry process (CIP and CIL …

This process can also be used for any acid or cyanide gold baths, already in solution form, that contain PGC. Also, it can be used for cyanide/H2O2 or most cyanide/m-NBSS gold stripping solutions. In these cases, just start at step (2). For cyanide baths or gold strippers, eliminate step (3).

Your response is really appreciated, I think you alright I have to decrease to 1 gram cyanide per liter. Regard my experiment, will use peroxide because am not concern about the cost since I just want to test the gold grade in the ore in minimum time, so I think I can finish dissolution the gold within 48 hours with peroxide and without use agitated leach.

Yesterday I did my first cyanide titration. This was based on GoldSilverPro's 2009 post cyanide titration, which was significantly clearer than the 11 pages given me from a professional mining services company.I first put together my own notes (shown below) and did a couple of qualitative tests to familiarize myself with what to expect at the end point.

OK. I do not have time right now to go in any detail but to make long time story short I can say that ecogoldex works exactly as advertised, gold is disappearing like snow in august. I guess I can safely say that it will dissolve gold in a speed I cant compare to anything I tried so far. I would compare it to straight cyanide - it is that fast.

Cyanide leaching is a method that has transformed the gold mining industry with its effectiveness and efficiency. The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution. From this solution, gold is later recovered, often by carbon adsorption.

gold from the cyanide? The only way to gold plate copper or brass is to first plate the surface with nickel. For allumnum they first plate with copper then nickel and then a final layer of gold.

I've never come across a rhodium cyanide bath. All of them are either phosphate or sulfate-based with various aryl/alkyl sulfonates in to relieve stress. Gold plating solutions do, however, contain cyanide. None of those chemicals he has are what's needed, nor does he have the equipment and experience to do it efficiently and safely.
