jewelry pendant trays square wholesale The main component of the sand is silicon dioxide.

The nitric acid separation method can use the nitric acid separation method, pour the thick nitric acid into the cup, and put the metal that needs to be refined into the cup. After that, the cup is placed on the cup frame, and at the same time heated it with alcohol lamps, and then you can get pieces of gold. 2. Wang Shui separation method can also use the Wang Shui separation method to refine the gold. After configured a part of nitric acid and three copies of hydrochloric acid into Wang Shui, put the metal that needs to be refined into the king water, and filter it after the metal reaction is over. Then heated it, and finally put it in the copper piece for replacement, which can also be refined. 3. The sulfuric acid hydration separation method mixes sulfuric acid and hydrogen peroxide in a ratio of one to one, and then puts the technology that needs to be refined into the sulfuric acid hydraulic solution. After the metal reaction is over, the yellow metal object obtained is gold. Gold -refined raw materials were previously refined by gold. The raw materials were mainly derived from gold ore. The gold -containing ore mined from gold mines also contains other precious metals. As we all know, the application of gold is quite wide. Electronic components, jewelry, batteries, medical films, lines, etc. are very widely used. Therefore, electronic garbage and jewelry waste can also refine gold and other precious metals.
