Abstract:
Silver is one of the earliest elements utilized by humans, and with the development of society and advancement of technology, its new material properties have become increasingly prominent.China is one of the countries with relatively abundant silver ore resources.Since 1990, and especially since 2010, there have been significant breakthroughs in the exploration of silver ore in China, with more than 55 000 tons of new silver resource reserves added and more than 53 new silver deposits discovered, including a large amount of silver ore from the super-large Shuangjianzishan deposit.There are seven main types of silver deposits in China, with hydrothermal and continental volcanic-subvolcanic types being the most important, accounting for 49.5% and 15% of the total reserves with resources of 161 271 tons and 48 870 tons, respectively.The majority of China’s silver deposits is from the Mesozoic era, with identified silver resources reserves of 266 476 tons, accounting for 74.25%; spatially, there is a distribution pattern of “more in the east, less in the west”.The Great Xing’an Range metallogenic belt and its adjacent areas have identified silver resources reserves exceeding 86 000 tons, making it China’s most important silver ore region and a potential area for exploration.Applying the theory of ore-forming series to find new mining areas or new types of silver deposit, the periphery and depth of old silver mining areas, and silver deposit within the silver-forming belts are important directions for the exploration of silver ore in China.
