The mineral pyrophyllite Al 4 (Si 4 O 10) 2 (OH) 4, a dioctahedral mineral with a 2:1 layer structure identical to talc (Fig. 3.11), also belongs to the clay mineral group (cf. Table 3.4).Though a relatively rare mineral, it is most commonly found in metamorphic formations exposed to low-temperature hydrothermal alteration which implies the presence of liquid water.

Since ancient times, a process called "scratching gold by goose feather" was used in the beneficiation of gold from placer gold. In the course of panning placer gold, the goose feather was dipped with plant oil for bonding fine gold particles. In fact, this was the special flotation with oils and fats as collectors.

Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.

Old-timers used the wind to separate their gold from the sand by tossing the gravel up in the air and catching it in a blanket. The gold, being heavier, fell in the blanket, while the wind blew away the sand. Using a modern portable drywasher is a lot easier! • Metal detecting is another great way to hunt for gold in the desert.

The gold occurs near the surface (100 to 300 feet) in a narrow, almost horizontal, quartz vein system with minor amounts of sulfides in the form of pyrite and arsenopyrite. In some of the quartz veins, all of the carbonacious rock has been naturally leached out, leaving the gold almost loose in the fragmented quartz veins.

This is by far the most important aspect of gold separation and recovery and includes angle, horizontal leveling, and water flow. Improper sluice angle is probably the most common error most miners make. The old rule of thumb of setting your sluice to "one inch per foot" is just a starting point and can result in too much water velocity.
