Rod Mill Work Index Table. Here is a list presented in table form of Rod Mill Work Index as tested/presented by SME handbook of mineral processing, N.L Weiss Editor, N.Y. 1985.
Rod mill is mainly used for processing and crushing raw materials such as feldspar, quartz and ore, and also for the fine and medium crushing of many kinds of hard and crisp materials such as refractory matter, cement, steel grit, slag powder, copper ore, iron ore, gold ore sand, concrete aggregate and pitch aggregate.
The mill will produce 8, 12.7, 15.6, and 19 millimeter-diameter rods. This is the fifth rod mill supplied by Primetals Technologies to Southwire for their wire and cable business. The company had previously ordered one copper rod mill and three aluminum rod mills from Primetals Technologies’ predecessor, Morgan Construction.

A 64% reduction in rod mill downtime at Codelco’s Chuquicamata. The Chilean copper producer Codelco entrusted Metso with the replacement of the pinions and gears for 21 ball mills and 12 rod mills at its massive Chuquicamata open pit mine, and the results have been remarkable. Codelco’s Chuquicamata mine in Chile is one of the largest open
Ordering a second mill identical to one supplied to the Southwire Company, LLC of Carrollton, Georgia, USA by Primetals Technologies in 2010, Ningbo Jintian Copper (Group) Co. Ltd. has signed a contract with Southwire for an SCR 3000 copper rod mill. The new mill will operate in Ningbo, Zhejiang Province, China. Start up is expected in the fall of 2017.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term ''rod mill'' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
China Copper Rod Mill
The rod mill and two ball mills are approximately the same size for simplified maintenance. Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated

Water is required for many activities at a mine-mill site, including ore production and beneficiation, dust and fire suppression, drinking and sanitation, and minesite reclamation. Assessing
Last month, the US producer also decided to close its Bayway specialty copper products operation in the state of New Jersey, a company spokeswoman confirmed. “On June 17, we announced the closure of our Norwich rod mill to gain efficiencies with our two other rod mill operations,” the spokeswoman told Fastmarkets.

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper
Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill.
