3 Technologies in Exploration Mining and Processing

Some recent grinding installations in Australia have demonstrated potential for ultra-fine grinding with acceptable power consumption (Johnson 1998). A combination of high-pressure rolls and ultra-fine grinding devices could potentially save energy in the production of ultra-fine particles because they create micro-cracks during the crushing step. An arrastra (or arastra) is a primitive mill for grinding and pulverizing (typically) gold or silver ore. Its 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.
