Whilst ‘free milling’ ores typically have recovery levels above 95%, refractory ores have recovery levels significantly below this, with some only achieving 50% to 60% recovery (Vaughan, 2004). Many refractory ores can be subjected to further processing to improve the cyanidation-based recovery rate, but often at greater expense.
The coins weigh in total 6 gms but because they're a 50/50 mix of silver/copper, the actual amount of silver works out to be 3 gms.
