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. Soft rock mining refers to excavation of softer minerals such as salt, coal ...
The grinding is usually done with hard ore pieces or hard steel balls, sometimes both. The product of crushing and grinding is a water–particle pulp, comprising ∼35% solids. Flotation is done immediately after grinding—in fact, some flotation reagents are added to the grinding mills to ensure good mixing and a lengthy conditioning period.
An arrastra (or arastra) is a primitive mill for grinding and pulverizing (typically) gold or silver ore s simplest form is two or more flat-bottomed drag stones placed in a circular pit paved with flat stones, and connected to a center post by a long arm.
