Ore Classification. The efficiency and recovery of chemical processes involved in gold extraction is exclusive to the mineralogy of the ore. Gold may exist as free nuggets or particles in alluvial or elluvial deposits or as native metal in other minerals.

Ore Processing Challenges in Gold Operation Grinding Circuits. By Scott Ferguson 06.16.2020. Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

Gravity gold is recovered by the use of five Knelson CD-30 Concentrators fed from the cyclone underflow. A Consep CS6000 Acacia Reactor is used to intensively leach the Knelson concentrate. The Acacia loaded solution has a dedicated electrowinning circuit. Gravity recovery accounts for up to 45% of the recovered gold, depending on ore type.

The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.

This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore. What this means is that in large scale mining the mines may have more than one crusher (primary, secondary and tertiary crushers) in order to achieve the desired crushing levels.

Crushing and conveying. At the gyratory crusher, we reduce approximately 150,000 tons of ore per day to pieces about 10 inches in diameter. We then transport the crushed ore by a five-mile conveyer system at the speed of about 900 feet per minute: three miles through a tunnel in the mountain and two miles above ground to the Copperton Concentrator.

For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets.

Gold extraction. Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870. 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

Crushing and processing gold ore takes some technique, trial and error, and some patience, but you will find plenty of gold in our ore. Many customers report anywhere between half a gram to a few grams a pound and some pieces are just veined all the way through making them far more valuable as specimens than for ore processing.
