One of the biggest problems for small scale prospectors is stubborn black sand deposits that keep them from being able to maximize the profits on the gold they have found. This article will talk about this problem and possible solutions that will help any small scale prospector deal with black sand effectively.
Most small scale prospectors try to find their gold in streams that have a history of having it found in them. The age old technique of panning for gold is still the most common method of prospecting done but there are also those that use larger equipment such as sluices, dredges and drywashers. If the equipment is laid out correctly and then used properly, then these methods are great at separating the lighter materials out and capturing some gold if it is present in the gravel you are running.
These captured gold particles are generally very small in nature and usually will consist of gold flakes or gold dust.
The big problem is that after any of these gravity methods are used there will be a lot of other heavy materials that filter out along with the gold these are commonly known among prospectors as concentrates.
If you are prospecting in a location that has been found to have gold, then most likely you will have some gold in the concentrate along with other trace materials such as black sands. Black sands are most typically made up of two types of crystalline iron oxides called magnetite and hematite. These black sands can pose a big problem when it comes to separating the gold from them.
After a prospector has spent all that time and effort getting to this point in the process, they certainly dont want to leave it up to chance to get all the gold out of the concentrate many times if gold is present in the black sands it is hardly even visible to the naked eye.
There are many different ways that prospectors get the gold out of the black sands. Below are a few modern tools that can really help with the separation process. There are certainly other types of equipment out there, but these are definitely some of the more popular ones. These range from about a hundred dollars to several hundred dollars, but they will last a lifetime if cared for properly.
