Traditionally, once gold ore is mined from the ground, it’s crushed to a powder and passed through a series of tanks in a process called leaching. Cyanide is then used to separate the gold from the ore into the leached solution. With the new process, the leaching and recovery process is done with chloride, one of two elements in table salt.

Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners.

Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process due to rheological and physiochemical properties are modified.
