Carbon Adsorption In Recovery Of Gold

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to ...

A gold ore with a 2 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.

The gold concentration is usually referred to as the gold 'grade'. and is measured as 'grams per tonne', written alongside results as 'g/t Au'. In some cases this same ratio will be listed as 'parts per million', written as 'ppm' (ie. there are 1 million grams in 1 tonne). The average gold grade of mined ore in 2009 was g/t Au (Schrodde, 2011).
