The electric smelting of nonferrous ores was tested fairly thoroughly 20 years ago by United States Bureau of Mines and by others, and the fact that it did not achieve continuing workable, success in any instance is sufficient proof that it offered no advantages at that time.
The principal advantage of directtocopper smelting is isolation of sulfur dioxide evolution to one furnace of high sulfur dioxide strength gas. Its main disadvantage is the large amount of copperinslag. The products of directtocopper flash smelting are copper, slag, and offgas with different volumes.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Chapter 8 Environmental Aspects of Copper Production
(but less easily quantifiable) benefits for human health and the environment, but also have had a substantial adverse impact on the competitiveness of U.S. copper producers.Any tightening of the present air quality or waste management requirements would result in further closures of domestic copper operations.
Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced . This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions .
What Are the Advantages and Disadvantages of Copper
The high price of copper is only expected to rise. While overhead electrical wiring generally uses aluminum due to its low cost, copper is the metal of choice for use in electrical components. Computers contain a large amount of copper, and copper recycling helps ensure that the total supply of copper does not fall unnecessarily.
How to Choose Gold Smelting Flux Superb Elctromachinery
Consequences of not using gold smelting flux in the gold smelting Process. Having mentioned the advantages of using Gold smelting flux. It is almost unimaginable to carry out a gold smelting process without making use of flux. We will however still outline the disadvantages of melting gold without flux.
Apr 24, 2017 · Every year in the United States, nearly as much copper is recycled as is mined. Excluding wire production, almost 75 percent of U.S. copper used comes from recycled copper scrap. There are so many advantages to recycling copper that the value of scrap is approximately 85 to 95 percent the price of newly mined ore.
8 Advantages to choosing fiber over copper cable Inside
Dec 08, 2011 · Fiber optic cable is one of the fastestgrowing transmission mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop appliions. Fiber offers a number of advantages over copper. 1. Greater bandwidth Fiber provides far greater bandwidth than copper and has standardized performance up to 10 Gbps.
What Are the Advantages and Disadvantages of Mining
What Are the Advantages and Disadvantages of Mining? Mining gives people a portion of the resources needed for modern civilization, but it can also lead to environmental harm. While some are in favor of mining due to the resources it produces and the jobs it provides in the U.S., some are opposed to mining based on opposition to destructive
What are the advantages and disadvantages of copper? Quora

The Smelting Industry: Global Importance And Risks
Apr 25, 2017 · The most used processes to smelt copper are reverberation and oxygen flash smelting. For both processes, the resultant molten copper is again processed to achieve the purest copper. Human Health Risks. Continued exposure of airborne pollutants generated by metal processing and smelting has been known to cause chronic diseases.
At the current time, it is more economical to smelt copper ore rather than to use bioleaching, since the concentration of copper in its ore is in general quite high. The profit obtained from the speed and yield of smelting justifies its cost. Nonetheless, at the largest copper mine of the world, Escondida in Chile the process seems to be favorable.

The Classic Ages: Stone, Bronze, Iron The Shorter Word
Iron, like copper and tin, must be extracted through a process called smelting to get it out of the rock or ore. Iron is never found in its pure elemental state. However, it is one of the most common elements on earth and therefore cheap and available. One of iron''s great advantages was that it could be sharpened.
