Silver Mining Process. The process of mining for silver is broken down into three steps: removing ore from the earth, breaking it down and then flushing the silver from ore. The first step involves drilling holes in the silver-rich areas geologists have previously pinpointed and then inserting dynamite sticks.

The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.
