Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh).

Today the US copper companies, despite the high cost of the world''s strictest environmental standards, are well positioned to live with low price levels and to profit from improvements in the demand for copper. Restructuring of the US brass mill industry in the past few years has been at east as profound.
Copper was consumed as refined copper and as direct melt scrap at about 30 brass mills, 13 wirerod mills, and 500 chemical plants, foundries, and miscellaneous operations. According to data compiled by Copper Development Association Inc. (2003, p. 18), mill and foundry product shipments to the market, including net imports of mill

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity . A freshly exposed surface of pure copper has a pinkishorange color . Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as ...
Events, Trends, and Issues: Although refined copper prices remained volatile during the first 10 months of 2012, they traded within a narrower range than in recent years. The COMEX spot copper price began 2012 at per pound of copper, rose to per pound in April, and declined to a low of per pound in June before trending

Copper Earth Rods These rods are manufactured from high tensile low carbon steel. All the rods are molecularly bonded by % pure, high conductivity copper bonding, each every rod is treated with Benzoltriazole derivatives. Roll threading process is used in order to form the threads on the rods. Which in turn provide
The copper industry in the United States has two main segments: producersmining, smelting, refining companies; and fabricatorswire mills, brass mills, foundries, powder plants. The end products of the producers, the most important of which are refined cathode copper and wire rod, are sold almost entirely to the copper fabricators.
Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh).
Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sandmaking.
