Our facility at Sparta uses natural gas and electricity to produce whole grain silica products. The reserve geology is that of high purity alluvial sands with the primary erosional source being the Wonewoc Formation, known for its round, coarse grains and superior crush strength properties, which makes it an ideal substrate for oil and gas proppants.

This plant mines sand through dredging, where the sand is extracted from the ground with water without the use of any chemicals. The sand is then transported as slurry via pipeline to the processing facility where it is sorted and dried in a no-emissions manner – with vibratory screens that use gravity and clean-burning natural gas dryers. 

Located along Iband and Hammer Road, just north of I-90, in Sparta, the property is ideally buffered by natural terrain and situated immediately adjacent to the Canadian Pacific railroad. 


We are committed to being a community partner with the Sparta community. Our Sparta plant community partners include Sparta High School, Sojourner’s Journey and Boys & Girls Club of Sparta.
