There is a lot of silver recycling as well. Although there are not many primary silver mines there is a lot of silver recovered secondary in mining operations of other metals.
Most silver that is newly mined is from copper/gold/lead/zinc/nickel etc. Most ores have a mis mash of all kinds of things in them.
take a look at any huge commercial mega mines production records and once they clean everything out of the metal. They may have
100,000 tons of copper
50,000 oz silver
12,000 oz gold
200 oz Pt group metals
Those are just numbers I pulled from no where but most will be in a decreasing order like that. All that silver gold and everything else also just ends up on the market and used somewhere.
Silver shortages may come up but the best cure for high prices has always been high prices. if silver hits $30 to $50 per ounce, you bet you will see silver mines reopen and exploration.
Or, like the hunt bros found out. Junk silver and old stuff will flood the market crashing the price.
keep in mind, silver was used for currency world wide, and a lot of it is still in that form. people start mining there closets cupboards and coin collections and all the sudden tons show up. how long this resource will last is unknown, but it is also unknown how much is stashed by investors.
Silver is used all over the place. Still in photos, Some electronics etc. Did you know that mos lap tops keyboards have about a 1/5th gram in that contact plastic sheet.
So silver is used industrially for many things but it could be a while before real shortages show up.
Also, if prices get too high, substitutes are found. silver coinage was replaced by copper and nickel, And for most solder contacts silver was replaced by tin. As more of the industrial usages cut costs and make products that are disposable after just a few years, They dont have to be built to last, so why use the silver? Digital photography and ink has replaced a lot of silver too.
Example, if a computer slot had gold on it, it was ment to last for decades, If the life of that computer is only going to be say 2 to 3 years. They use a cheap tin wash rather than gold.
Things just balance out eventually.
