Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm—0.4 mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits a rod mill is usually superior to and more efficient than a ball mill.

Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from on-the-ground reconnaissance by prospectors to remote sensing techniques such as satellite imagery. Mine excavations take place either on the surface or ...

gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
