Is iron sand dangerous?
Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.
Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
As such it forms a hazard in New Zealand at popular west-coast surf beaches such as Piha..
Is Black Sand dangerous?

Is gold found in black sand?
Black sand is composed of a mix of iron-group metals: Hematite and Magnetite. … Black sand can also be a byproduct in operations that mine zinc, copper, and other metals. Gold ore and black sand are commonly found together, so prospectors often start their searches in areas with lots of black sand.
