Yes, all good food for thought. Thanks for your reply seasoned with such careful consideration for what all is at stake here.
Should you, or anyone other qualified, like to pursue any of this in a shared profitable sense, in consideration of all this, please feel free to make me your best offer. At this point I'm willing to be the supplier. Supplying 1,000 pounds of the LCD glass screen material, which currently consists of sheets of all the same 46" LCD glass screens, all removed from the same manufacture's same make and model high-end commercial displays. FOB, Chicago, IL 60491.
note: For future consideration, I too agree that further consideration be made for the recovery of other precious metals and rare-earth elements, not just for the recovery of the gold alone. For starters, one of such is Indium, being one of the firsts to be recovered based on it's properties. Research and testing has discovered that the recovery of Indium from LCD screens is achievable, through a chemical process. First choice to mill and disintegrate the LCD screens to a particle size less than 75 micrometers, or about 0.003 inches, in size. Secondly, through a leaching process, it was tested possible to extract 96.4 wt.% of the indium under the following conditions: 1.0M H2SO4, 1:50 solid/liquid ratio, 90°C, 1h, and stirring at 500 rpm. Finally, precipitation of the indium with NH4OH was achieved with 99.8 wt.% at pH 7.4. The results showed that the best experimental conditions enabled extraction of 613 mg of indium/kg of LCD powder.
However, I'm neither a chemist nor a refiner qualified for any of this. Even though I've done my share of many experiments and testing along these lines, I'm not qualified, but I'm willing to share my positive results as well as past mistakes. All I have to offer could quite simply be what I have here. Hopefully, this will be enough of what you need to get you started. All I'm asking for is that you give me your best offer, and give this your best shot. Wishing you continued success!
