How to Test Ore or Rock for Gold Content
Sep 15, 2016 If no gold or native silver can be seen in the rock, take a representative sample of about 300 grams and grind it up to pass a No. 30 sieve. Weigh out 250 grams and carefully pan down until most of the gangue is removed. Examine the heavy residuum for metallics. Should any be found it will be well to see how much can be amalgamated.

How much gold is in a ton of ore? Quora
No matter what process you use to recover the gold from the ore, you will never achieve 100% recovery, therefore you must allow for it in your calculation. 12 t = 12,000,000 g Assuming that your recovery is 90% and your feed grade is 5 g/t, then you will recover 4.5 grams from every tonne mined. So your calculation is:
