Which is more expensive, iron ore or sand?

Iron ore is expensive.

The iron ore price of load-bearing sandbag leggings is generally around 25 yuan, and the sand is about 15 yuan, so the iron ore in the market is generally more expensive.

Iron ore, including iron ore pellets, sprayed iron ore and counterweight iron ore, is mainly used for sand blasting pretreatment of steel surfaces.
