The Story of the Sand Dunes
A sand dune is simply a pile of sand deposited by the wind. The word "sand" refers to a particle size- approximately the size of a grain of sugar. Sand happens to be just the right size to be blown by the wind and then deposited to build a sand dune. Often a dune forms around an obstacle such as a rock or clump of grass where the wind ...

The six main steps of iron ore processing
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
