Silica Minerals represent the group of minerals being composed of silicon and oxygen forming the chemical formula SiO 2. Silica can occur in macrocrystalline, crytocrystaline and amorphous form. Industry predominantly uses the crystalline form of silica, i.e. quartz. Silica is used as granular products containing the particle size range >63 µm.

One of the easiest and most inexpensive ways to separate gold from dirt is through panning. This age-old technique has been around since the Gold Rush, and makes a great outdoor hobby that can pay for itself. With a minimum of equipment, the beginner gold prospector can separate gold flakes and nuggets from the surrounding strata in a nearby stream.

There are many elements that have an affinity for gold that destroy its properties, making it brittle. In order to insure that gold that is used in jewelry has the normally required ductility, refining is highly recommended. It need not be electrolytic---gold of excellent quality can be produced by the acid processing method.

How can you separate gold from other metals? The most common method used to separate gold from other metals is by using a panning technique. Panning mainly involves swishing water and sediment around in a pan in order to separate the heavier gold particles from lighter ones. This process works best with small pieces of gold, such as flakes or dust.

50% gold mixture isn't a problem to melt directly, that's enough to separate and get the gold to melt together. But from your description I'm not totally convinced that you actually have gold. Pyrite and mica is often mistaken for gold and is a lot harder to separate, but if it melts together into a metallic blob then it was probably gold. Göran

With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
