Silver is a simple metal with the symbol of Ag, which has ductility and good thermal and electrical conductivity.
Silver, namely silver, is called silver because of its white color, as opposed to gold. Think of it as money and decorations. In ancient times, money was called silver. Pure silver is white in color, metallic in luster with impurities, soft in quality, hardened with impurities, and grayish red in color. Pure silver has a specific gravity of 10.5, a melting point of 960.5℃, good conductivity, and is soluble in nitric acid and sulfuric acid. Silver is one of the metals found in ancient times. Although silver also exists in the form of simple substance in nature, most of it exists in the form of combined state. Silver has high ductility, so it can be rolled into a transparent foil with a thickness of only 0.3 microns, and silver particles with a weight of 1 g can be drawn into filaments about two kilometers long. The thermal conductivity and electrical conductivity of silver are among the best among metals.
Silver has always been the "shadow" of gold, but it is different from gold. Although silver has precious metal properties, its main use is still reflected in industry. Since 2007, the international silver market has been in a state of oversupply. According to the data of the World Silver Association, the global silver supply in 20 12 was10.48 million ounces, 8.9 million ounces more than that in 201year. Among them, the mineral output increased to 787 million ounces, an increase of 3.8% compared with 20 1 1, mainly due to the export of lead-zinc ore by-products. The supply of major silver mines increased by 1% year-on-year, accounting for 28% of the global silver mine output. Among them, the total output of silver in China ranks first in the world. In recent ten years, the output of silver mines in China has almost increased by 100%. The output of silver in China keeps increasing at a rate of over 10%.
Societe Generale released a report saying that it is estimated that there may still be an oversupply of more than 4,000 tons of silver in 20 13 years. Barclays Bank predicts that the global silver supply will reach 32,347 tons in 20 13, an increase of 0.8% compared with 20 12. In 20 13 years, the overall global silver supply exceeds demand, and there may be an excess of 644 1 ton. In 20 14, the global supply will reach 32775 tons. In the case of decreasing demand in the silver industry and slowing investment demand, the supply growth of silver mines is still strong. The author predicts that the pattern of oversupply of 20 14 silver will continue, and the increase or decrease of actual investment demand will determine the trend of silver price.
