Great Salt Lake Minerals Company, Utah

One of the largest salt works on the Great Salt Lake with two major evaporation pond areas: 19,000 acres at Little Mountain, where this plant is located, and a 17,000 acre field of ponds 21 miles across the lake, near Lakeside. The brine from the Lakeside field flows in an open canal underneath the lake surface (the concentrated brine is heavier than the water above it and stays in the canal). The brine takes as much as 10 days to make the journey through the canal to this plant. 375 people work at two facilities here, extracting potassium sulfate (for fertilizers), sodium chloride (for industrial salt applications), sodium sulfate (used in laundry detergent and glass), and magnesium chloride.
