Prairie River Minerals is moving forward with a mineral processing demonstration plant near Coleraine. The plan is to start construction in April.


The company said they will be taking ore from existing hematite stockpiles, and turning it into lump and sinter ores that can be used to make steel.

CEO Larry Sutherland, who recently retired from U.S. Steel, said in a statement, "I am excited to join the PRM team and help develop this innovative business utilizing ore stockpiled from the early days of MN iron mining.  We’ll bring good paying union jobs to this region, be environmentally friendly, and benefit our local communities and the State of Minnesota.”

Johann Grobler, the developer of the Ulta-High Dense Medium Separation technology will serve as technical director for the project.

The hope is to employ about two dozen people at first, and then grow from there. But there will also be contractors who will be helping out as well.
