With the rush of metal consumption in the last decades and the expected raw material demand driven by the clean and digital transition, a growing concern has emerged about the decline of ore grades.
To remain competitive, the domestic metals industry must not only make advances in mining methods, but also in ore processing. One processing advancement under investigation is the development of nonconventional solvent extraction (SX) stripping techniques such as hydrogen, hydrolytic, and precipitation stripping.
Soak / wash the carbon for a couple of hours in 3%-5% HCL is often necessary to dissolve the junk, making for a cleaner strip of the gold-cyanide complex. …
Adsorption: The gold-cyanide solution is passed through activated carbon to adsorb the gold. Elution: The loaded carbon is subjected to elution to strip the gold from the carbon. Electrowinning or Smelting: The gold is recovered either by electrowinning or smelting, depending on the chosen recovery method.

The main advantage of the AARL process is the ability to strip a batch of carbon to low gold residuals in an average strip time of 6–8 hours compared with 6–10 hours for standard Zadra. New plants can be designed with multiple daily stripping cycles in mind, or existing plants can have increased daily capacity by adding shifts for stripping.
Gold mining in the People's Republic of China has made that country the world's largest gold producer by far with 463.7 tonnes in 2016. For the year 2007, gold output rose 12% from 2006 to 276 tonnes (9,700,000 oz; 304 short tons) to become the world's largest for the first time—overtaking South Africa, which produced 272 tonnes (9,600,000 oz ...
