Physical properties of minerals Crystal Form • External expression of a mineral's internal structure • Often interrupted due to competition for space and rapid loss of heat Crystals are the smallest "bits" of minerals and reflect the geometry of the mineral Department Environmental Earth Atmospheric Sciences molecules
The amount of black sand and other heavy minerals which you find associated with your placer gold varies a lot – there is not a simple direct correlation There are places that are loaded with black sand but have no gold Conversely there are also places that have good quantities of gold but very little black sand

Mineral sands are within a class of ore deposits that contain heavy minerals such as ilmenite zircon leucoxene and rutile The most important naturally occurring minerals that are mined to produce titanium dioxide (TiO 2) feedstock are ilmenite leucoxene and rutile The minerals are either used as feedstock in their natural form or in an upgraded form such as synthetic rutile and titania
to form an alloy which helps separate the precious metal from rock sand and other material The alloy — or amalgam — is then heated often in a shovel or metal pan over an open fire to vaporize the mercury leaving behind only the gold 1 Amalgamation is carried out in different ways including whole-ore and heavy mineral concentrate
