Using waste electronic products to extract gold, the specific operation steps are as follows: classifying, disassembling and crushing all kinds of gold-containing wastes; Soaking the crushed waste in an acid solution to dissolve gold; Reducing liquid gold; The reduced gold is dissolved in a melting furnace and then cast into ingots. According to the invention, gold is extracted by a wet method in a non-toxic manner, the acid used in the reaction is neutral after reacting with gold, and the discharged wastewater is neutral, thus causing little environmental pollution and achieving the effect of environmental protection.
Gold is a simple form of chemical element gold (Au), which is a soft, golden yellow and corrosion-resistant precious metal. Gold is a rarer, more precious and more valuable metal. Generally speaking, gold in the world is measured in ounces. In ancient China, gold was measured in ounces, which was a very important metal.
