Hi. I have a few ounces of very small gold flakes mixed with sand etc that I panned at Tadmor a while ago. A magnet from an old hard drive(in a plastic bag)removed all the ironsand effectively but the remaining opaque sand and tiny garnets are hard to remove.Using a high-powered magnifying glass it is possible to sort out 1 grain at a time!

Not only did it separate the -100 from the black sands, the amount of gold that the Black Magic lost in the -30 to the -100 range was eye opening. The Black Magic is put away and waiting for a buyer. I'll never run anything smaller than a -20 in anything other than a Blue Bowl.

Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.

Those powdery materials might contain small flecks of gold, silver, and platinum scrap. The application of high heat causes those precious metals to separate and be left behind after dust, sawdust and other undesirable contents are reduced to ash. Give us a call at 800-426-2344 and we can explain how this works.

Under the action of flowing water, gold ore fragments are brought into the river and further shredded during the handling process, slowly separating the gold out of the ore. Since gold is a large specific gravity mineral with a specific gravity of 19.32 g/cm3, fine gold will deposit at the corner of the river (slow flow rate), forming the ...

Mixtures of liquid and solid can also be separated using filtration. This is ideal for separating solid particles that are light and fine from liquid. Filtration is done with the aid of a filter paper which helps separate the solid particles from the liquid called filtrate. The solid separated by the filter paper is called the residue.
