Silver Ore Mining Overview

ilver is a metallic chemical element with the chemical symbol Ag (argentums) and atomic number 47. A soft, white, lustrous transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Silver is a very ductile and malleable monovalent coinage metal with a brilliant white metallic luster. Most silver is produced as a by-product of copper, gold, lead, and zinc refining.

Silver has long been valued as a precious metal, and it is used to make ornaments, jewelry, high-value tableware, utensils, and currency coins. Today, silver metal is also used in electrical contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are used in photographic film and dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides. While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues.
Silver is found in native form very rarely as nuggets, but more usually combined with sulfur, antimony, arsenic, or chlorine and in various ores such as chlorargyrite and argentite.
Silver Mining Process
Silver is commonly extracted from ore by crushing, grinding,smelting or chemical leaching. SBM crushers have a very important role in silver ores mining eespecially in silver ores crushing process. The jaw crusher is commonly used as the primary crusher and impact crusher, cone crusher is used as secondary

Nigeria has a vast amount of untapped mineral resources. However, mining Nigeria is not very popular before. The mining of minerals in Nigeria accounts for only 0.3% of its GDP, due to the influence of its vast oil resources. The domestic mining Nigeria industry is underdeveloped, leading to Nigeria having to import minerals that it could produce domestically, such as salt or iron ore.

Rights to ownership of mineral resources is held by the Nigerian government, which grants titles to organizations to explore, mine, and sell mineral resources.

By the 1940s, Nigeria was a major producer of tin, columbite, and coal. However, because of the discovery of oil in 1956 , mining Nigeria’s mineral development has been highly focussed on its oil industry. You know Nigeria is Africa’s largest oil producer and contributes 3% to global production. As a result, the mining Nigeria industry has been neglected and has only been rekindled by the Ministry of Solid Mineral Development, intent in increasing the role of this sector of Nigeria’s economy.

Currently mining Nigeria contributes more and more to Nigeria’s GDP. Nigeria has significant coal and iron ore reserves as well several gold, uranium, tantalum and REE showings throughout the country. We believe crusher manufacturers in China will find their way in mining Nigeria.
