The gold jewelry of the piece is the same as the common weight gold recovery. Calculated by gram, it will lose about 40%-70%. . What is gold recycling: Gold recycling (usually referred to as recycling gold), which is to recycle gold products or gold -containing items. The basic purpose of its recycling is or realized or reused. Most of the gold recovery also also operates the sale of the sale, platinum recovery, and gold recycling. Gold recycling is different from the recovery of general items. Whether it is the weight of weight, the determination of the color, or the price determination, it forms a unique recovery system. Because the gold recovery is re -used after recycling, it is also said that recycling gold is regardless of the brand. The main price factors of recovery are determined by the gold content and international basic transaction price. . What is gold: Gold (GOLD) is a single form of chemical element gold (AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and extremely valued metals. Internationally, gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments. The chemical symbols of gold are AU, and the English code in finance is XAU or GOLD. The name of the AU comes from a story of Aurora, a goddess of dawn in Roman mythology, means shining dawn. . The physical and chemical nature of gold: The chemical properties of gold are stable and have strong corrosion resistance. They do not respond to oxygen at high temperatures at high temperatures (but except pure oxygen under specific conditions under specific conditions ) Gold will not react with oxygen and sulfur at high temperatures. The chemical properties are very stable. They are stronger than silver (silver will be oxidized at 1500 degrees to generate silver oxide. The situation will be oxidized by one. This at room temperature is soluble in solution containing potassium cyanide or sodium cyanide to form a stable complex M [AU (CN) 2]; Middle; it is also dissolved in an acidic solution with chlorine gas. Gold does not work with alkali solution, but it can be generated with sodium peroxide when melting. The combined price of gold is -1, -2, 1, 2, 3, 5, 7, etc. Oxide has a triple oxidation two gold AU2O3, and chloride has a three-chloride gold AUCL3. In in an acidic medium, chlorine h [AUCL4] or complex M [AU (CN) 2] can be restored to metal zinc (zinc powder or zinc wire), sodium sulfate, and hydraulic crickets, etc. The sulfide of the alkali metal will corrode gold and generate soluble sulfide gold. Exic acids in the soil and metabolites of certain bacteria can also dissolve trace gold. This of gold is high, it is difficult to lose the outer electrons into positive ions, and it is not easy to accept electrons into anion. Its chemical properties are stable and the affinity with other elements is weak. Therefore, most of the natural gold state exists in nature. The pure gold in nature is very small, often including silver, copper, iron, 钯, 铋, platinum, nickel, 碲, selenium, 锇 and other accompanimental elements. Natural gold contains 15%of silver in silver More than 20%of copper are called copper gold ore, 5%-11%of 钯 钯 钯 钯 钯 矿 矿 钯 铋 铋 铋 矿 矿 矿 矿. This has a parental sulfur, and is often close to sulfur such as pyroneite, poison sand, square lead ore, and 锑 ore.

Although the gold bought by the items is very expensive, it is only recovered when recycling. So the gold you buy is not preserved.
