Consider melting or smelting your gold, silver, and other metals yourself But first understand that there is a big difference between melting and smelting. Melting means to change something from a solid to a liquid by the application of heat.
Alluvial and HardRock Gold Recovery. Gravity Separation has been applied to mineral separation applications for centuries. The HPC technology focuses on the fundamental physics of any gravity separation process and is designed in such a way that the machines can be adjusted to allow concentration of virtually any Heavy Particles.
We need to separate the gold from everything else in the rock so the rock needs to be treated in some way. In New Zealand we chiselled some rocks from an outcrop near a small creek. We were pretty sure our rocks contained some gold as there were disused gold mines dating back from the 1870s close by.
Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds.
