Transcript of Silver

Where silver mines are found?
Silver is found in over 56 countries but the top 5 producers are U.S.A., Canada, Mexico, Peru, and China. Canada ranks 11th place with 19.6 million ounces of silver a year. The top 4 provinces in Canada are Quebec with 29%, Ontario with 24%, New Brunswick with 18%, and British Columbia with 16% of Canada's silver production. In 2009, New Brunswick produced 184 tonnes of silver, Quebec with 155 tonnes, Ontario with 138 tonnes and British Columbia with 74 tonnes.
Where is it located?
Silver is located in North America, Australia and some parts of Europe and South America.
How is it mined?
Where was silver first found
Silver has been used for many items since ancient times. It is found all over the world, but there is evidence of silver nuggets being found as far back as 4000 B.C. That is 6000 years ago. Therefore silver has been around for a long time. Silver has been used as currency, or money for a very long time. In the early 1600's, silver was used for manufacturing some materials.
Substitution for silver
There is another element that is almost the same as silver. It is called graphene. In 2020-2030 we are expected to run out of silver. The element graphene is cheaper than silver. Using graphene in electronics can make your device load faster. There are even some companies replacing silicone computer chips with graphene.
Definition of silver
Silver-a precious shiny grayish-white metal. The chemical element of atomic number 47.

presentation on Silver.
How much does it cost to obtain it?
Cost involved with buying and selling silver
More Info
In the early 1400's, the vikings used silver for many materials we use day to day. For example coins. Their system was: the larger and heavier the piece, the more it's worth. They valued silver, and even presented it to the aboriginals when they landed in Newfoundland. Then they even traded it for other materials. They valued silver since it was a strong material and was durable.
Then, in the early 1600's, silver was beginning to skyrocket in the materials most used. The Europeans used silver for many items. They mined the ore, and melted it to get the silver. After it was melted, it was used for many household items, or even weapons.
Major importer of silver
India is the major importer of silver in the world with 462 tonnes of silver monthly. They buy 22% of the worlds production of silver.
Major exporters of
China exports more then half the silver that they produce. They will cut their silver exports by about 40% in 2019. They are going to cut it because in 2020 we are expected to run out of silver. They are going to put it in reserve to sell for a higher price after the world runs out of silver.

Silver mining began about 5000 years ago.

Silver was first mined in about 3000 B.C. in Turkey. These early lodes of silver were a valuable resource for countries like the Near East, Crete, and Greece
•In ancient Egypt and Medieval Europe, silver was often more valuable than gold.
•Words for silver and money are the same in at least fourteen languages.
•Silver's melting point is 1761 degrees F or 960 degrees C
•The name silver came from the old english word seolfor.
•Silver is harder than gold, but softer than copper.
Silver is at least 99.9 percent pure.
Most silver is mined underground where a part of silver ore have been located along with other minerals. Finding these parts involve drilling into the ground and exploration methods. Other methods happen in open pits. Silver is extracted after all of the other minerals have been removed from the silver ore, and then the silver is lifted out of the pit where all of the mined ore is.

When we mine silver, we need to look all the people or machines (that mine, crush etc) that are in the picture of the mining process. For starters, we need to pay the miners that mine the silver out of the rock. Then we need to pay for the trucks or conveyer belts that bring the ore out of the mine. Then there's the two crushers that crush the ore into tiny pieces. (more info will be explained in the video) Next the silver needs to go into another machine that melts away the other minerals, leaving pure silver. In total, mining silver, as well as any other mineral cost a lot.
