The life of the mine is a key element in the design of any crushing plant. Shortterm mine lives (three to eight years) require a very careful approach to design, layout and construction. Since the crushing plant's structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize ...

At the Spanish Mine, Nevada County, California, there are four Huntington mills, three of 5 feet diameter and one of 4 feet diameter. The ore is freemilling and is passed through a Blake stonebreaker and thence to the mills. The four mills run at 58 revolutions per minute, and pulverise 35 tons of ore each in twentyfour hours, to pass ...

The key to a successful process plant design is the implementation of a wellstructured, comprehensive testwork program. It is important that this program is developed and executed in parallel with the exploration of the deposit and that the results are used to assist in the planning and understanding of the continuing exploration.

Small Mineral Processing Plant Design / Construction. Small mines are almost invariably adit rather than shaft mines, and in most instances ore is trammed directly from mine to coarse ore bin at the mill for crushing. Accordingly, most mills are situated adjacent to the portal of the main haulage level. In a few cases, location of the mill at ...
