For the recycling process it is important to have a single kind of plastic. There are multiple techniques available to identify plastics like Near Infrar

Amalgamation: Using Mercury to capture fine gold, retort

Basically, amalgamation is the practice of bringing free gold particles into contact with mercury. When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam – an amalgam is simply an alloy of gold and mercury. The gold literally is dissolved into the mercury.

Artisanal and Small

Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices.

Mining Techniques of the Sierra Nevada and Gold Country

Mining Techniques of the Sierra Nevada and Gold Country by Snowy Range Reflections staff Gold panning was slow even for the most skillful miner. On a good day, one miner could wash about 50 pans in the usual 12-hour workday and obtain a small amount of gold dust. Separating the gold from the crushed ore proved to be a problem. Due to

Gold Mining Methods

The stereotypical grizzled gold-rush prospector panning for gold was searching for placer gold, or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, sluice-boxing, hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold from the lighter sand and gravel.

Mineral processing

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

An Overview of Basic Gold Separation Methods

3. Gravity separation process used in gold separation. Because of the large proportion of gold, gravity separation process is the most common method of recovering gold, and is often used in combination with other gold separation methods to treat all kinds of gold ores, especially the alluvial gold mine.

Magnetic Separation

For instance, in a few situations, plants using gravity concentration for recovering gold, used magnetic separators to remove the high concentration of magnetite that was recovered with the gold, prior to further processing. Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required.

Magnetic Separation Method

Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser (though noticeably) affected are known as
