Copper is extracted in large amounts from the Earth’s crust by mining of sulphide ores and also oxide or Studies reveal about 80% of copper is produced by its extraction from sulphide or Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate or
collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated  Pyrometallurgical copper production Figure 3: Typical flow sheet for pyrometallurgical copper production from ore concentrates The large blast and reverberatory furnaces of the 1900s were derived from these principl Later.
About Copper mining and mining photo from copper mines in India by N G Nair Manager (Mines) Malanjkhand Copper Project Hindustan Copper Limited, Mining Engineer , Blasting in Mines an Art or Science ? N G Nair the only name you can trust on Mining Consultancy , Iron ore is the raw material used to make pig iron
The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting The mixture of water, foaming agent and paraffin is recycled After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate
Copper ore can be found anywhere from y=131 to y=45 It is a very common ore and doesn't require to be smelted to craft copper ingots It can eventually be combined with tin to make bronze Tin Chunks Tin ore can be found anywhere from y=100 to y=50 It is tougher than copper and is a 'furnace-less' alternative to iron , Blasting Explosive
A new iron ore deposit is to be worked by surface mining , Cast blasting is the controlled placement of overburden into the previously mined cut resulting in a reduced volume or overburden material for the dragline to handle 19 , H_BLASTING IN SURFACE EXCAVATION
The blast broke up 300,000 tons of ore which provided material for eight months! The original method of processing the ore was to pile it up with wood The wood was then set on fire and the ore smelted Processing at the time of the mine closings differed considerably , The mining of the Copper Basin ores was a magnet for people to come into .
Jul 14, 2008· Best Answer: Copper slag is the waste product of copper ore smelting It is normally processed to produce usable grit for sandblasting of metal surfac It is extensively used in shipbuilding, ship repair, and other steel fabrication industri The copper slag ,
Glossary of Mining Terms , Muck - Ore or rock that has been broken by blasting , Solvent extraction-electrowinning (SX-EW) - A metallurgical technique, so far applied only to copper ores, in which metal is dissolved from the rock by organic solvents and recovered from solution by electrolysis
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 sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts
The Process The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnac The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage)
The copper ore bodies mined from 1911 to 1938 at Kennecott, Alaska (now within the Wrangell–St Elias National Park and Preserve), are examples of potentially environmentally “friendly” ore deposits The ore bodies consisted of veins of massive chalcocite (a mineral consisting of copper and sulfur)
Extracting copper from other or Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution
