To solder gold, first you'll need to get some gold solder and a precision torch. Once you have your supplies, prepare a water bath and a pickle bath, which is a solution used to clean oxidization off metals. Then, holding the gold in place on a soldering block with copper tongs, apply a small amount of flux to the gold and heat it with the torch.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ... Gold …
