Hard Rock Mining Gold and Silver Ore and processing it
There are a number of different haulage methods for transporting rock through a mine to the portal. The old timers commonly used rail and mining cars to move gold or silver ore and waste rock, and this method is still used in some smaller mines. Most modern mines however, use rubber tired diesel powered equipment to haul ore underground.Silver mining - Wikipedia,Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable by-product, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge…Underground mining (hard rock) - Wikipedia,Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
