Silver plays a gigantic part in technology. If you look in any electronic device right now, silver would definitely be present. In conclusion, the main reason I support the mining of silver is because silver is used in many if not all of the everyday things we use. If we stop mining silver, the efficiency of our lives would change drastically.
Silver mineralizes most commonly as argentite, polybasite and proustite, Ag 2 S, 16 Sb 2 S 11 and Ag 3 AsS 3 respectively . Methods for mining silver vary between mines depending on factors related to the ore body, such as the grade of the ore, its depth, host rock, and economic factors.
Silver mining is the resource extraction of silver by mining. It is a mine where silver ore is dug. Most of the worlds silver production in 2015 came as a byproduct of lead zinc, copper, and gold mines. Silver ore is mined through both open pit and underground methods.
Silver is generally found in the combined state in nature, usually in copper or lead mineralization, and by 2000 bce mining and smelting of silver bearing lead ores was under way. Lead ores were smelted to obtain an impure lead silver alloy, which was then fire refined by cupellation.
1. Overview of Mining and its Impacts1 Proposed mining projects vary according to the type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental
Silver is an extremely rare metal only occurring in igneous rock at a concentration of only 0.07 parts per million. For comparison, copper is approximately 785 more prevalent. Due to its rarity ...
The firm ResearchGate examined the grades of the 12 biggest primary silver mines in the world. They specifically measured the mill feed grade, which is the grade of the ore going into the mill. Their data only goes through 2016, but look what has happened to the average grade of these deposits over the past 10 years.
