The grade of the ore from which gold is to be recovered will determine how much of it must be processed to recover that ounce of gold. There is a broad variation, but there is plenty of gold in ores that is dispersed so widely that it is not economical to attempt commercial recovery. In an additional note, gold exists in veins within ores, and is not chemically combined with other elements within that ore. Mines that are probably considered marginal yield something on the order of 4 to 6 grams of gold per ton of ore, and you can do some simple math from there (perhaps using 5 grams/ton) to discover an answer for the stated grade of ore. There are just over 30 grams in a Troy ounce, and at 5 grams/ton, you're looking at 30 divided by 5 or 6 tons of ore to recover that (Troy) ounce of gold from ore with a grade of 5 grams/ton. If you have 6 tons of ore, that's a lot of ore, and you have a lot of hard work ahead of you if want the ounce of gold disbursed in it. It will take time and energy to win the metal, and it might be as cheap to buy the gold as to recover it from the ore. But we'll leave it for you to do the math after you get an assay.
