Silver Ore
Preparation of Silver Ore. The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a conducive alkaline conditions for the extractions.

Horn Silver and the Nevada Rush. The Nevada silver rush, which began in 1858, may be the truest example of a gold rush. In the California gold rush, like those before and after, the Forty-Niners swarmed into the land and panned the easy nuggets from the stream placers. Then the geologic pros moved in to finish the job.
