Domestic refined copper demand grew by about 5% in 1998 owing to demand for wire mill products and substitution of refined copper for scrap at brass mills. In June, a new wirerod mill was commissioned in Texas. Worldwide, consumption grew by only about 2% in 1998 owing to the economic crises in Asia. In 1999, continued low global

For its extensive practical experience, 911 Metallurgist has a clear understanding of what successful mineral processing engineering is and how to go about achieving goal is the production of a material that is marketable and returns you and your investors sustainable revenues.

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

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.

[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. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter.

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.
