    To be specific let us take the example of a copper ore whose grade or copper content is only 1 by weight Let us assume that the sole copper mineral species in this ore be chalcopyrite which is one of the most popular copper minerals found in copper ores in our planet The chemical formula of chalcopyrite is known to be CuFeS2.Most copper production is based upon sulphide ores containing little copper but quite a lot of iron New cleaner technologies are now important but older processes present major environmental problems Complex procedures are used initially to form a form of copper sulphide appropriate for final reduction via a copper(I) oxide.

  • Copper Smelting Process

    Copper ores An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper it is worth extracting when there is about 2 kg of copper per 1 000 kg of ore (0 2 ) Copper minerals are found in over one hundred varieties although only a few have been worked for copper on a large scale.Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace Molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 99 9 purity Copper can be recycled indefinitely without the base metal being compromised.

  • Rock & Soil Sampling – The Key To Most Exploration

    The availability of copper is low in many foods due to the tendency of copper to bind with organic matter Copper is present in normal human serum (the liquid part of blood) at concentrations of 120 140 g L Signs of toxicity will be seen if the copper concentration rises significantly above this range (Bradl 2005 Wright and Welbourn 2002).Prior to the discovery of Cadia Hill Iron Duke (Big Cadia) had been by far the largest producer in the district having yielded than 100 000 t of secondary copper ore @ 5 to 7 Cu from underground operations from 1882 to 1898 and 1905 and 1917 and 1 5 Mt of iron ore @ approximately 50 Fe from 1918 to 1929 and 1941 1943 (Welsh 1975).

  • The 10 Biggest Copper Mines In The World

    El Teniente copper mine the world’s sixth biggest is located 80km south of Santiago in the Andes mountain range in Chile It is also the largest underground copper mine in the world El Teniente was estimated to contain 15 2Mt of fine copper (1 538Mt of ore grading 0 99 copper) at the beginning of.This means that 95 7 of the copper present in the ore was recovered in the concentrate while the rest was lost in the tailings (c) The Cu Loss can be calculated by subtracting the Cu Recovery from 100 Cu Loss = 100 – 95 7 = 4 3 This means that 4 3 of the copper present in the ore.
