Apr 15 2012nbsp018332Even though separating joined and mixed materials poses a challenge for recycling the total energy requirement for recycling a ton of iron is some 20% lower than for mining and processing it. For copper the energy saving is approx. 60% and for aluminium even 90%. Expressed in saved carbon emissions these numbers look even better.

The extent of local processing varies according to the physical characteristics of the minerals. The purely technical necessity of processing is of course greater for copper ore of which the metal content is between 0.5% and 4% than for iron or bauxite ores which have a grade of 50% or more.
Reduction of ores using coke (e.g. iron) made from cheap coal is cheaper than the electricity bill for extracting aluminium from its molten oxide by electrolysis but different metals have different properties best suited for particular and different uses.
in phytomining plants can absorb copper ions from lowgrade copper ore as the grow. This could be on slag heaps of previously discarded waste from the processing of copperrich ores. Then the plants are burned and the metals can be extracted from ash. The copper ions can be quotleachedquot (dissolved) from the ash by adding sulphuric acid.

ore flux \ m The Egyptian copper smelting furnace was filled with a mixture of copper ore charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag which was tapped off.
About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps the copper concentrates are usually treated by pyrometallurgical methods. Generally copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate

Mar 14 2014nbsp018332A typical open pit iron ore mine is shown in Fig 1. Fig 1 A typical open pit iron ore mine. On the basis of mining methods iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines.

Conservation of copper ore To date only about 12% of known copper resources have been mined. However copper ore is a finite resource and it makes sense to conserve ore by recycling. Economics It is cheaper to recycle old copper than to mine and extract new copper. Recycled copper is worth up to 90% of the cost of the original copper.
Energy and Environmental Profile of the Mining Industry 5.1.3 Copper Processing Prior to pyrometallurgical the ore (which often contains less than one percent copper) is crushed and ground with water and placed in a concentrator. The rock/water slurry is subjected to physical and chemical actions (i.e. air sparging and hydrophobic chemical
The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas which have separated into metal sulfides and siliceous melts.
Mining of iron ore is a highly capital and energyintensive process. Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro LCA software as a case study.

Copper is rarely found in its native form most often it exists as ores made up of various copper sulfides and oxides that have little practical value of their own (Australian Atlas of Minerals Resources and Processing Centres). As such methods for mining copper involve long and complex chemical processes to produce metal from the ores.
It consists of three areasthe Emily District the North range and the South range. Although much smaller than the Mesabi iron range to the north the Cuyuna was a major producer of iron ore for 80 years. More than 106 million tons of ore were mined and shipped from the Cuyuna range between its discovery in 1904 and 1984 when mining ceased.
