Metallurgical studies by Resources Gold Technology begin with consideration of the information obtained in a pre-feasibility study. Gold processing routes are evaluated and a gold extraction process is selected. The characteristics of the gold ore are investigated from a representative sample of the ore deposit.

the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

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 processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
