Reactions & resistance to chemical and mechanical demolition of minerals

The minerals that are particularly heavy and resistant to chemical and mechanical demolition can be found with the gold in placer deposits. This is more frequently known as black sand. Black sand consists for the most part of magnetite, however some of the other minerals that can be found in sluice boxes are tungsten minerals, cinnabar, platinum, chromite, pyrite (more commonly known as fool’s good), hemitite, zircon, and garnet. There are in addition a number of other minerals and things that can be found such as amalgam, metallic copper, quicksilver, nails, and many other things. When the cross section of a river has gone through down faulting on the upstream side it produces a pocket that catches and traps the gold gold, gravel, silt and sand as well as titanium minerals, and every so often diamonds have also been found. Gold is high in gravity and is close to six or seven times higher than quartz and augments up to nine times in the water and this is what causes the gold to work its way to the bedrock or journey until it gets trapped. After it has been caught in the bedrock it is not easy for the stream to raise it again. The specific gravity of gold is of nineteen and this means that it is nineteen times as much as the same amount of water to its mass.
