Metal Detection
Gravity Separation
With Gold’s density being substantially higher than most elements, the effect of gravity becomes more pronounced with unspecified, combinations of material samples containing gold compared to similar spatial volumes of material that do not. In fact the effect is so pronounced that gravity separation is the most adopted method of separating natural gold from the environment host material by.
Gravity gold separation is best achieved with earth, rock or host materials of similar size particles, so advance preparation of the material is necessary. This is done by screen, trommel or particle traps that allow for larger material to roll off into the tailings pile and retains material of suitable size ranges. A “grizzly” is a screen mesh on a frame that earth/rock material is shoveled through by prospectors to obtain consist ant size particles for sampling and concentration. There are many types and features to various grizzly’s that will be discussed in the equipment section.
Gravity separation can be accomplished wet or dry. Even though the effect of gravity
is on bodies under water is diluted by the density of the water, wet methods such
as panning, sluicing or centripetal methods often benefit from fluidization of the
material even at the expense of lower difference in gravity effect. Properly employed
most wet methods of gold separation can frequently capture 90% or greater free gold
on the first pass. Wet methods prevail over dry because the fluidization of the particles
break down and dissolve the earth and rock so that smaller particles may become un-
Dry material separation methods are employed where it is to impractical or costly to use wet separation and processing methods. Its more critical for material also to be processed for size using Dry gravity separation techniques. This means in addition to screening, dry mud balls and deteriorated soft rock encountered must be finely crushed.
Hard rock material is harder to separate by gravity methods, although it can be accomplished. Because hard rock gold separation by gravity requires more complex mechanical and chemical methods to process, its best to have a small sample properly assayed first to be certain the expense overcomes the cost of processing.
