Jan 14, 2019 The regression equation for copper determination was A 2.9003C 1.8 10 2, where A is the analytical signal the difference between the absorbance of the sample and blank solutions A A s A b at 324.8 nm and C is the copperII ion concentration in solution g mL 1.
ores, however, require rather sophisticated recovery techniques. Different ways of gold concentration p15. 1.1 Gravity concentration Gravity concentration is the oldest technique for gold recovery. It makes use of the high specific gravity of gold that amounts to 19.3. The devices developed and used for gravity concentration are innumerable.
burden waste-to-ore ratio for surface mining of metal ores generally ranges from 21 to 81, de-pending on local conditions. The ratio for solid wastes from underground mining is typically 0.21. Where concentration or other processing of the ore is done on site, the tailings generated also have to be managed. Ores with a low metal con-
which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation amount of copper metalamount of copper ore rock100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade 200100001002 3.
the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years.
