- Name of the facility:
Mesabi Nugget LLC, Erie Nugget Plant
- Location:
Hoyt Lakes Mining Area, Hoyt Lakes, St. Louise County, MN 55750
- Distance from the US/Canada border:
- Type/size of the facility:
The Mesabi Nugget facility will be the first iron full-scale iron nugget
plant to be built. The raw materials for the process will consist of various
coals, fluxes , and binders, as well as iron ore concentrate from Silver Bay,
Minnesota. The coals and fluxes will be pulverized on-site, mixed with
binders and iron ore and fed into a rotary hearth furnace. The furnace will
convert the ore into iron nuggets and slag. The iron nugget will then be loaded
onto railcars. The facility will have the capacity to produce approximately 600,00
tons of iron nuggets per year.
- Source of emissions:
Sources of emissions include a rotary hearth furnace (RHF), green ball dryers,
coal and flux pulverizer/dryers, material handling and storage, a backup generator,
and cooling towers.
