The processing system is a Merrill–Crowe Process which is a separation technique for removing gold and silver from the solution obtained by the cyanide leaching of ores on the leach pad. After the solution passes through clarifiers, zinc powder is used to precipitate the precious metals from solution.
Ore trucked from Amancaya is batched through the plant due to its higher silver content. Ore is passed through a three stage crushing process, prior to entering the 1500 tpd agitation leach plant. Pregnant solution is passed into a MerrillCrowe circuit where gold and silver are extracted and a gold and silver dor233 is produced.

REFRACTORY ORE PROCESSING. The common definition of “refractory” gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
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 piled into heaps for ...
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. 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 ...
Process Manager. Jim Gubler was appointed to the position of Process Manager. Mr. Gubler’s experience in Merrill Crowe processing and heap leach management will be valuable to the Company. Mr. Gubler has made an immediate impact by identifying and implementing several corrective measures to the mine’s processing. Site Maintenance and ...

Gold is mined in the form of microscopic particles in concentrations as little as 0.5 parts per million ppm. As a result, simple tools have been replaced by complex equipment and chemical processes to extract gold. Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows

Gold and silver are recovered using the MerrillCrowe method, and a refinery produces goldsilver dor233 bars on site. Metals recovery in the plant is expected to average 95 for gold and 54 for silver over the remaining life of the mine. In 2019, the Company began testing samples from Pinos Altos and La India relating to an ore sorting project.
KCA also manufactures modular MerrillCrowe recovery plants for operations processing up to 10,000 tonnes of goldsilver ore per day ranging from 20 to 500 m179hr KCA Modular MerrillCrowe Brochure . A list of projects for which KCA has fabricated modular plants is presented below.
