Hi Strenlich, When you dissolve salt in water, the sodium and chlorine are separated by polarization to the water H2O. We call the process ionization. The salt in all portions of the water will equalize perfectly. If you shine a light through the water, the light will show no reflection against the salt. If you take mud and mix it in water, the water will become muddy. If you allow the mud to settle, the settled portion is slimes. The brownish portion that stays resident is not ionized into the water and is there as particles so small that the molecular activety of the water (Brownian Movement) will keep the particles from falling to the bottom. These particles or suspended particles will reflect light and the beam of light will show as a beam passing through the particles and water. Another type of colloid is the charged colloid. It is held in the water because of polarity, but no ionization has taken place. These charged particals can also follow the rules of uniform distribution just like salt, but they are still considered colloid. When gold is dissolved in solution, it is dissolved as a salt Na-AU-CN. When gold is dissolved as a microcluster, it is there as a charged molecular colloid, when gold is suspended as colloidal gold in slimes, it is held by an attraction to the clays and passes as a mixture with the water in what the metallurgists refer to as slimes. There it is not truly a colloid, but is affixed to clay colloids and for all practical purposes is a colloid. Remove the clay and that gold will quickly drop to the bottom. That rule was, as I understand it, first proposed by Herbert Hover (President and Mining Engineer) from his placer research in gold processing at Timberlake Creek at or about 1900. Today Timberlake Creek is considered a DD. It has tremendous potential. mike
