18 ensp 0183 ensp calculated in the same way as copper concentrate but levels Free metal The value of the free copper gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate LME copper price and LMBA gold and silver price In this example the recovery rate for a copper smelter is 98 0 The
It was observed that 17 of copper goes to the tailings and the lowest copper recovery was for particles coarser than 105 μm of 1 183 5 in the final copper concentrate grade at constant
2 ensp 0183 ensp Lead zinc and copper smelters each having different smelting practices either give a low return no payment or a penalty for metals adverse to the particular process For instance copper contained in a lead concentrate is paid for at or near the price paid for lead while lead in a copper concentrate will return less than 50 of lead price
How to Calculate the Percentage Recovery of a Product Multiply the result of your last calculation by 100 The result is your percent recovery of that chemical for the procedure For the example you would multiply 0 572 by 100 and report that you observed a recovery of 57 2 percent
Finally we should remember that the theoretical grade recovery curve is generally defined for the value minerals in an ore and not based on the final element metal to be recovered From the example here if we looked at Cu recovery the theoretical grade recovery curve would correspond to figure 5
6 ensp 0183 ensp copper concentrate would result in a maximum payability of 95 per cent of the contained metal value to the miner Metal recovery in PGE smelting is typically reported to be between 95 per cent and in refining over 99 per cent A deduction of 10 per cent or 90 per cent payability of contained
21 ensp 0183 ensp Electrorefining of Copper 1 Electrorefining – General Introduction In an electrorefining process the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis i e the electrode reactions are at the anode M → Mn ne and at the cathode Mn ne → M
19 ensp 0183 ensp recovery minor copper recovery and copper grade responses were optimized using JMP statistical software Indicators of model inadequacies were noted but since the models predicted sensible solutions inaccurate test ratios and un modeled effects were hypothesized to be the source of the inadequacies The model predicted 98 copper recovery

12 ensp 0183 ensp How to calculate grade and recovery concentrate Location ore grade is obtained by sampling alpha concentrate grade and tailing grade beta V calculated using these data concentrate yield The calculation formula is as follows According to the calculation theory and the actual recovery rate of two methods
For the water quenched slag at optimized conditions 64 65 of copper was recovered in one stage flotation and a 4 54 copper concentrate was achieved Flotation technology is not suitable for copper recovery from water quenched reverberatory furnace slag
The texture of particles within a flotation cell play a pivotal role in both mineral recovery and the grade in the flotation concentrate Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade recovery possible for a given feed ore
