Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.

Gold mining companies assume responsibility for the management of a site long after a mine has closed and been dismantled – typically for a period of five to ten years or more. Over this time, the land will be rehabilitated – cleansed and revegetated – and the mining company will work to ensure the gold mine reclamation and return to long-term environmental stability are successful.

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost

Albion Process™ has real-world success in delivering consistently high recoveries – up to 97% in refractory gold and over 99% in chalcopyrite copper concentrates. It has much lower capital cost than traditional leaching plants like pressure oxidation (POx) plants and because it operates at atmospheric pressure, it completely avoids the myriad of risks of POx plants.
