Most barite that have been dated are far older than the firstland plants. These have evenly distributed micro barite that show no sign of transport by magma.A common misconception is that barite are formed from highly compressed coal.

It is possible that barite can form from coal insubduction zones, but barite formed in this way are rare, and the carbon source is more likelycarbonaterocks and organic carbon in sediments, rather than coal.

The concentrator ore discharged from heavy medium concentrator machine, can use barite ore grinding plant to select barite concentrate.
