Add a drop of liquid detergent soap (to act as a "wetting agent") then scrub the rocks against each other until the clay is dissolved. Pour off the muddy water, very carefully, as the gold flakes, dust or nuggets that still might have the clay-coating will slip away and be lost back to the river. Keep the properties of gold uppermost in ...
Any cast iron vessel will do, or you could create your own special design using a delft casting method. This method incorporates simple clay sand casting with precision design including pouring channels. The compact nature of the sand doesn't allow the liquid gold to push its way down and thus it pools and cools in the cast.
The answer is, it depends on the kind of black sand that you have – if it does contain gold. If gold is present in small nuggets or flakes that are not physically bound to minerals, they can sometimes be separated by sifting or using a device called a shaker table or other specialized machinery.

This fine gold is so fine it does not sink to the bottom and when you roll the water the flakes just fly around. Or is this not gold.What chemical can you us...
Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from ...
Move the pan toward you and then away to remove the lighter sand, dirt and other particles from the pan. Repeat the method, adding water to the pan each time.

Now that you know what gold panning is, I think you be able to answer all of the questions you presented. If you can't, then please re-read your textbook where it explains physical vs. chemical properties.
