Silver is a noble metal with the highest electrical conductivity of any element. it also has the highest thermal conductivity of any metal, and is an excellent optical reflector. not only has silver been used as currency, but also it is widely used in jewelry, tableware, electronics, x-ray and other medical and dental films and photographic prints.
Extraction of metals. what is a metal ore. a solid element or compound which occurs naturally in the earths crust is called a mineral.a mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.
Mountains of silver and gold. the city, born in 1859, only took a year for miners to become proficient in digging underground to find both gold and silver. one early method included square-set timbering, developed by a german engineer, which allowed miners to safely extract ore from hundreds of feet below the surface.
Apr 25, 2017nbsp0183325. metals extracted through smelting. smelting is a process of extracting metals from their ores at high temperatures. ores are mostly chemical compounds of metal with other elements, like oxygen sulfur. smelting utilizes heat, and a reduction agent like coal, to extract the other elements from the metal according to cornish mining world heritage.
While many technologies exist, silver is typically mined through a process that uses gravity to break and extract ore from large deposits. the exact method of ore removal used varies by the physical characteristics of the rock surrounding the metal, as well as the unique shape of the deposit.
Silver is a soft, white metal that usually occurs in nature in one of four forms 1 as a native element 2 as a primary constituent in silver minerals 3 as a natural alloy with other metals and, 4 as a trace to minor constituent in the ores of other metals. most of the silver produced today is a product of the fourth type of occurrence.
