Gold mining
Hard rock mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska.The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold.

Precious Metal Mining in Colorado
Hard-Rock Mining Instead of hydraulic mining, most of Colorado’s gold and silver were taken out by mining the bedrock. Miners started using this method in the early 1860s. Lode or hard-rock mining required digging shafts and tunnels into the mountains, following the veins downward from the surface.Most of the gold and silver produced comes from the processing of hard rock ores. There are a lot of different options for processing ores, and in the article below I'll take a look at all of the best known possibilities for getting the gold and silver out of your ore and producing a clean gold and silver bullion product.Hard Rock Mining Gold and Silver Ore and processing it
