On the method of extracting gold from vinegar and hydrogen peroxide
Now there is a method of extracting gold from vinegar and hydrogen peroxide, which is worth exploring. Vinegar is an ordinary thing, and it is involved in life and diet. And hydrogen peroxide is not rare and has oxidation properties. The two are combined, and they are used to extract gold, which has other wonders.
Gold is a precious metal, which is stable and insoluble. However, vinegar with hydrogen peroxide can gradually dissolve gold. The weak acidity of vinegar can help the oxidation effect of hydrogen peroxide. When hydrogen peroxide encounters gold, it is difficult to react quickly, but in the medium of vinegar, its oxidizing property is obvious.
When operating, prepare gold materials first, or gold jewelry debris, or gold-containing ore powder. Place it in a clean container, and slowly inject an appropriate amount of vinegar and hydrogen peroxide mixture. Initially, there is no significant sign, and after a while, the solution gradually turns yellowish, which is a sign of gradual gold dissolution.
However, this process also needs to pay attention to many matters. First, hydrogen peroxide is oxidizing and corrosive, and the operation should be careful not to touch the skin and eyes. Second, the reaction rate is affected by factors such as temperature and concentration. If the temperature is too high, hydrogen peroxide is easy to decompose, resulting in gold extraction efficiency loss; if the concentration is improper, it is difficult to achieve the desired effect.
After the reaction is completed, if you want to obtain pure gold, you need to follow up the separation and purification method. Or use precipitation to make gold ions settle; or use electrolysis to obtain pure gold.
Gold extraction with vinegar and hydrogen peroxide, although not a new method, it is a feasible way to extract gold under simple conditions, which can add a practical solution for the recycling of precious metals.
