The concentration of a mineral in the ore body % or g/t 2% copper and gram per tonne gold Strike Length The length in which the mineralization is found in the ore body horizontally 500 meters Depth The depth in which the mineralization is found in the ore body vertically 200 meters Width The width in which the mineralization is found in a drill hole 100 meters Specific
Copper deportment in the ore varies signi cantly from mainly chalcocite in the open pit fi ore to predominately chalcopyrite in the underground ore In both ore sources gold is present as free gold and granularly locked in copper sulfi des and pyrite The ore processing plant consists of two parallel trains Train 1 and Train 2 which are currently treating a total of 21 Mt/a This includes
cubic meter m 3 gallon gal Mass metric ton ton short 2 000 lb metric ton per day ton per day t/d 1 Estimated Water Requirements for the Conventional Flotation of Copper Ores By Donald I Bleiwas Introduction This report provides a perspective on the amount of water used by a conventional copper flotation plant including the makeup water required to
Higher grade ores are usually put through more complex milling processes where higher recoveries justify the extra cost The process chosen depends on the properties of the ore The final product is cathode copper Nickel ores This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals
· For example an overburden thickness of 100 meters and an ore thickness of 50 meters would yield a strip ratio of 2 1 That means mining 1 cubic meter of ore would require mining 3 cubic meters
Probable Reserves of copper ore are 454mt at % copper % zinc /t silver and % Molybdenum Probable Reserves of Zinc ore as of January 2010 stand at 149mt graded at % Cu % Zn /t Ag and % Mo Measured indicated and inferred resources during the same time stood at 130Mt 581Mt and 489Mt respectively Silver is associated with both ore types while copper
· A 13 m × 6 m meter SAG mill had a cylindrical feed chute 1 m in diameter It was charged with 70% slurry of gold ore and steel balls cm in diameter which occupied 8% of the total inner volume of the mill The entire charge occupied 42% of the internal volume If the porosity of the charge is 30% estimate Mass of balls charged 1 Mill
