In the above table, weights are expressed as ounces Avoirdupois. To express as ounces Troy (for gold, silver, palladium, platinum and rhodium) multiply the weight given in ounces Avoirdupois by 0.91146. The current efficiency of a process may vary according to the operating conditions and the solution composition. The figures given in columns 2, 3, 4 and 5, are based on a current efficiency of 100 per cent, and in using these tables correction must be made for the actual process efficiency.
