The well-documented toxicity and environmental concerns around the use of cyanide in the gold mining industry 12 has led to the adoption of the International Cyanide Management Code, a voluntary program intended to reduce the potential exposure of workers and local communities to the harmful effects of cyanide. It is estimated that cyanide leaching is used in around 90% of gold production from

E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium (Pd) and platinum (Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components. E-waste is classified as hazardous material, therefore, should be managed properly.

Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds. On the other hand if you are going to be processing large quantities

That kind of machine is nothing new. It is rather expensive and if you are going to buy it you will better stick to what it is designed for. It work with certain type of plastic only so I guess sticking printed circuit board in it will not be advisable and practical. I would compare that to ore crusher and coffee blender.

Instructions: Preheat the PCBs to let''s say a bit below 100 °C, then quickly give them a shot with the heat gun with a max. temperature of around 350 °C. All components should fall off within 5 seconds. 700 °C is far too much! A strong blower will just blow the heat (and the fumes) elsewhere.
