ppm ore grade would have 2 pounds of gold for every 1,000,000 pounds of ore. An equivalent unit is grams/ton (since there are 1,000,000 grams, or 106 grams, in a metric ton). Thus a 2 ppm grade gold ore would also have 2 grams of gold for every ton of ore. 1) A gold coin called a Krugerrand has approximately 31.1035 grams of gold in it. a.

Free Gold | Gekko

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
