Understanding Classification.

   There are five types of classifying in the process of separating gold from the
materials it is found in.

  Although gold is found in sizes ranging from specks too small to see, up to pieces to large to lift, most of the gold found by weekend prospectors range from pieces as small as the tip of a pen, to nuggets as large as a quarter. The most common equipment used in the field classifies off anything larger then a ˝ inch and runs everything under a ˝ inch through the equipment and is possessed for the gold it contains. Some prospectors prefer to pre-classify their material with a screen, like the Grunt Cub or one of the bucket top units. The larger material can then be inspected with a metal detector to rule out the possibility of missing a large piece of gold in the tailings pile.

  Also known as specific gravity, gold can be classified according to it’s weight compared to the materials it is found in. This is done with water or air. Dredges, High bankers, Sluices, Spiral wheels, Blue bowls, Rocker boxes and gold pans are types of prospecting equipment that use water and gravity to separate gold from other material. Dry-washers, both puffer and leaf blower types use air to classify the heavier gold from the lighter material.

  Gold is non-magnetic and can not be picked up with a magnet. Other material found with gold, like black sand have an iron property that allows them to easily be picked up with a magnet and removed. Some prospecting equipment, like the large vibrating tables use a combination of water and magnets to separate gold from material.

  This might sound like a topic that’s to easy to list but, all that is yellow is not gold. I have seen a lot of people that are new to gold prospecting picking up everything that is shiny and some shade of yellow, only to have their joy taken away when someone with a little more experience tells them that what they had spent all day collecting is not gold. If your not sure that the yellow stuff your picking up is gold, bust it up and put it in a gold pan. If it don’t act like gold by sinking to the bottom of the pan, it’s not gold.

  Only a metal detector can find gold without using many of these steps. By discriminating iron and lead from announced targets, the metal detector classifies according to type of metal it reacts to. Thus removing the need to classify according to size and weight. Metal detectors are only limited by the size and depth of the gold.

  All in all, separating gold from the material it is found in, takes a variety of classifying steps. The choice is up to the individual prospector's preference.

Classify to color.
Keep all yellow,
