Compass Minerals currently produces two primary products: salt and specialty potash fertilizer. The company's main assets include rock salt mines in Ontario, Louisiana, and the United Kingdom. The fertilizer is produced from a brine operation at the Great Salt Lake in Utah that produces sulfate of potash and magnesium chloride. Compass' salt products are used for deicing and also by industrial and consumer end markets. The firm's sulfate of potash is used by growers of high-value crops that are sensitive to standard potash.
