the mining process of silver
Silver mining Wikipedia
Silver has been known since ancient times Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC The silver mines at Laurium were very rich and helped provide a currency for the economy of ancient Athens, where the process involved mining the ore in underground galleries, washing and then smeltingit to produce the metal Elaborate washing tables still exist at the sitWhile 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 depositHow is Silver Mined APMEX®In the early days silver was refined by smelting and cupellation Later, when the Spanish discovered much richer silver mines in Mexico, Peru and Bolivia, they used the Patio process The process is attributed to a mining specialist – Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silverHow the process of mining for silver works Fraimed
Silver Mining and Refining Education
Silver is extracted from lead ores in large furnaces, a process called cupellation Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century In this process, crushed ore is placed in a bathWe’ve found an excellent little YouTube excerpt by the Discovery Channel on the process of mining and refining silver If you have 5 minutes, you’ll enjoy knowing a little more about silver and how it makes it from the soil to your safe megan Recent Posts Buyer Beware!Excellent Description of the Silver Mining Process 13082020 Silver is generally found in the combined state in nature, usually in copper or lead mineralization, and by 2000 bce mining and smelting of silverbearing lead ores was under way Lead ores were smelted to obtain an impure leadsilver alloy, which was then fire refined by cupellationSilver processing Britannica

How silver is made material, making, history,
Process Silver was first obtained in sixteenthcentury Mexico by a method called the patio process It involved mixing silver ore, salt, copper sulphide, and water The resultant silver chloride was then picked up by adding mercury This inefficient method was superseded by the von Patera processThe patio process is a process for extracting silver from ore The process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by Bartolomé de Medina in Pachuca, Mexico, in 1554 It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas Although some knowledge of amalgamation techniques were likely known Patio process Wikipedia15082020 Silver processing Silver processing The metal and its alloys: Even silver that has been fully workhardened, either by rolling or forging, gradually recrystallizes, even at room temperature This greatly softens the metal, making it susceptible to scratching and marringSilver processing The metal and its alloys

Silver can be enriched by gravity separation, but its enrichment degree is much lower than that of gold It is usually processed by a jig to collect coarse (greater than 01~02 mm) heavy minerals, namely natural silver, argyrite and hornsiliteWhile the flotation cyaniding method is the most important process among the three Silver concentrate can be get in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement and silver ingot can be finally get after the last process of electrolytic dissociationExtraction of Silver, Silver mines, Silver Recovery The patio process is a process for extracting silver from ore The process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by Bartolomé de Medina in Pachuca, Mexico, in 1554 It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas Although some knowledge of amalgamation techniques were likely known Patio process Wikipedia

The potash solution mining process Unlike conventional mining, which involves moving large amounts of dirt to access a mineral resource, solution mining requires boring injection and recovery To separate ore from waste rock, drill samples are sent to an assay laboratory for analysis The assay results are used to mark out zones of ore and waste rock, which are mined separatelyExcavating the rock – Waihi Gold
