No, they are in heterogenous form mixed: not as atoms or molecules but only as particles they mix, you can easily separate them by physical methods: a magnet will pick out the iron particles.
mixture
Iron filings would be made from comon steel stock, which would embody carbon in its makeup. Ignoring that distinction, iron filings could be considered a uniform material. But soon subject to oxidation.
Homogeneous
A salad is an example of a mixture. --------------------------------------------------------------------------------------------------- A mixture is a physical combination of two or more substances;that is, the substances are mixed without any chemical changes. Mixtures can be either homogeneous or heterogeneous. In a homogeneous mixture, the composition is uniform. Sugar in water is a homogeneous mixture. In a heterogeneous mixture, the components can be more easily identified as there exists two or more phases. An example of a heterogeneous mixture is a salad, or a mixture of sand and iron fillings.
The easiest way is with a magnet. It'll attract the iron and not the copper. If you're on a higher budget, the difference in the melting point could help.
Use a magnet to lift out the iron filings.

No, iron filings are not a mixture
you an use a magnet to get the iron fillings out
Mixture
If it is pure iron then it is considered to be a homogeneous mixture. Homogeneous is when a substance is the same thing throughout.
it is a heterogenous mixture
Iron fillings can be extracted with a magnet.
No, Iron is a homogeneous mixture as long as the iron is pure
Homogeneous
Use a magnet.
