What is the source of the iron/sand mixture? Is it recycling from a sand blasting set up?

I often wish they would zoom out on these videos fo expose the big picture of why the processes are taking place.

The sand is obviously very fine grained with a near zero moisture content. This seems to be a very small, controlled process to remove the iron impurity from the sand. Maybe to make the sand less conductive

From Wikipedia, the free encyclopedia

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron. It is typically dark grey or blackish in color.
It is composed mainly of magnetite, Fe3O4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.
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.

Hate tp get those little iron slivers in my feet. Hidden sea spines are bad enough.

If the sand is going to be used in downstream chemical processes or for uses such as filtration, or as an “aggregate” in various other substances (like non expanding grout), it may be desirable to have as little iron in the sand as possible. At the lab I’m currently working at they call this process of magnetically separating iron from sand or other small aggregate “beneficiation.“
