PHILADELPHIA, November 2, 2011 – FMC Wyoming Corporation announced today that effective immediately, or as contract terms permit, it will increase the price of its Grade 260 “dense” soda ash sold to customers in South Africa by $20 per metric ton. This increase is in addition the $30 per metric ton announced in April 2011. The increase is necessary for FMC to recover increasing costs and continue to invest in its operations as the global demand for soda ash increases.
