korean jewelry wholesale earrings In the world's largest underground gold ore, miners mine 6,000 tons and gold ore from 800 meters deep ore every day. Each ton of ore can be used to refine five grams of gold.
First, first, they use deep holes to drill in a specific way, drill out the holes of explosives, and then explode the salt warehouse with explosives. The mucosa factory on the ground. The crushing machine here puts a large piece of ore like a small piece like a road -like piece, and then press it into fine powder through the grinding machine. Then add a hydrogenation solution to another grinding machine to grind the ore with fine powder into mud -like. Subsequently, it will flow into the large sedimentation pool, and the heavier objects will sink to the bottom of the pool, overflow the upper layer of water to another area. Then transfer the solid of the bottom of the pool to the mixing groove and pour the oxygen. The oxygen can make the gold in the ore react chemical and the hydride, so that the gold dissolves and flows into the nearby water. The solid is separated, and then pour the zinc powder to make the dissolved gold precipitated, forming the debris of Korean stars and gold.
. In order to refine the debris into gold bars, workers must first mix a variety of chemicals as aid solvents, including manganese dioxide, fluoride, quartz powder, borax, and sodium nitrate. It can separate gold from impurities, and then pour Zhu Rongji into the melting furnace. At this time, the temperature in the furnace is as high as 1,200 degrees Celsius. Two and a half hours later, the heavier gold will deposit to the bottom, and the slag composed of magazines will float on the surface.
It, the residue can be exposed and sampled. If there is gold inside, it must be returned to the furnace to melt until there is no gold. After heating the gold to 1200 degrees Celsius again, pour it into the strip -shaped mold. After four minutes, the gold will be completely solidified, and then put in cold water for an hour to completely cool the gold bar. Clear the shroud of the surface residue. At this time, the goldenness of the tattoo is only 80%, and it needs to be refined to 99.9%to meet the international gold standard.
