In order to extract the pure silver, these ores have to undergo a refining process. Bronze Age people achieved this by heating the silver ore and blowing air over it, a process called cupellation. The silver does not react to the air, but the base metals such as lead and copper oxidize and separate from the silver.

How was silver smelted in ancient times
A variety of ore crushed by horn tools was crushed and melted in clay crucibles. There were no bellows in America, so the high temperatures required for smelting were usually achieved by a few people who blew through pipes into a living fire. Charcoal has been used as fuel elsewhere.
Which method is used for refining of silver
For the production of high purity sterling silver, electropolishing is used in almost all cases.
How do you purify silver
Add 3 parts distilled flux to 1 part nitric acid. Place on stovetop or stovetop and boil until all impurities are gone. Add 10 parts of tap water. Filter the accumulated chloride through a plastic funnel through a sieve with a filter.
When was silver first refined
According to the RSC, the first information about silver mining dates back to 3000 BC. in Turkey and Greece. The ancient Americans even figured out how to clean silver. They heated the jewelry ore and blew it with air – a special process called cupellation.

Generic methods are methods that expose their own type parameters. This is equivalent to declaring a generic choice, but the scope of the type parameter is simply limited to the method in which it is subsequently declared. Non-specific static and non-static methods are allowed, as well as general class constructors.

What is the difference between a class method and a static method class methods are inherited static methods aren’t class methods are passed the calling class static methods aren’t class methods are faster
With the static approach, no parameter is focused. The class method can access and view the state of the class. A static method simply cannot access the location or change the class. The class.method method takes the primary parameter class.as to get the primary state of that class.
