History Fifty million years ago, southwestern Wyoming, including the land now occupied by FMC’s Green River facility, was covered by a landlocked lake. As the earth changed through the ages, the lake evaporated and left behind a 200-billion ton deposit of pure trona wedged between layers of clay and shale. This is the world’s largest known deposit of trona. Trona is a mineral that is chemically sodium sesquicarbonate, and is the source of both the sodium and the carbonate used to manufacture soda ash.

This monumental deposit was first mined by FMC in 1948. Today the mine, located 1,500 feet below the surface, contains nearly 3500 miles of tunnels and covers 36 square miles. In the early 1950’s, FMC began producing soda ash at the world’s first natural soda ash processing plant. Since those pioneering days, FMC has become the largest producer of natural soda ash in the world.

Responsible Care, Sustainability & SafetyFMC places the highest priority on our commitment to the environment and to the dedicated people who work at our facilities. FMC has a responsibility to protect the health and safety of our employees, business partners, neighbors and customers. Maintaining a safe and healthy work environment is paramount to the operation of our business. Protecting our most precious resource, our employees, prevents injury, which sustains the performance of our business and maintains the trust of the communities in which we operate.

Natural soda ash production is substantially less energy intensive and produces less harmful pollutants than synthetic methods. We strive continuously to incorporate safety and health into every part of our company’s work culture. FMC is engaging in sustainable innovation by maximizing the use of less toxic and safer materials in the design and development of new products; and where possible, working to replace existing products and chemistries with ones that are more benign or more beneficial. FMC is a signatory to Responsible Care as set forth by the American Chemistry Council in the US and committed to complying with the seven functional areas of Responsible Care: Pollution Prevention, Process Safety, Employee Health and Safety, Community Awareness and Emergency Response, Distribution Stewardship, Product Stewardship and Security.

A prehistoric rock called trona. Trona, a mineral primarily containing sodium sesquicarbonate, is mined and processed into sodium carbonate, commonly known as soda ash, at our Green River facility. The origin of trona dates back fifty million years, when the area was covered by the 600 square-mile land-locked inland sea Lake Goshuite. As the earth’s climate changed and water evaporated, trona was deposited. This process left behind more than 200 billion tons of trona wedged between layers of clay and shale. FMC’s facility at Green River sits atop a reserve of trona large enough to meet alkali demand for many decades to come.

FMC offers a wide variety of soda ash grades for a spectrum of applications and uses. By offering the broadest selection of grades, FMC provides our customers with exceptional application specificity and flexibility. FMC was the first to produce light density soda ash and continues to offer the most natural grades available.

Production MiningAs you walk across the ground at our Green River facility, it’s hard to imagine the tremendous activity taking place beneath your feet. Fifteen hundred feet below the ground and accessed through one of several FMC mine shafts, is an around-the-clock mining operation.

FMC pioneered longwall mining for the natural soda industry by adapting this efficient coal mining technique to trona mining. A powerful longwall shearing machine moves along a 750 foot wide face of the trona seam, removing trona with cutting drums. The recovered trona is then dropped onto a continuous conveyor system and moved to the surface. The longwall method extracts 50% more of the trona deposit than traditional mining methods.

In addition to mechanical mining, FMC developed and patented solution mining technology. In our current implementation of this technology, water and insoluble tailings are injected into ‘mined out’ areas that still hold unrecovered trona. Water dissolves the residual trona, forming an alkali-rich solution which is then pumped back to the surface for processing. The result is a high-purity, low-cost soda ash that dramatically increases our ability to deliver value and volume to the world markets.

Advanced mining techniques have been one cornerstone of our success. Over the years these methods have enabled FMC to stay a step ahead of the competition and economically expand our capacity to meet growing market demands.

ManufacturingFMC’s Green River, Wyoming surface operation is the world’s largest natural soda ash facility. FMC has five surface plants capable of producing nearly 5 million short tons of soda ash per year. FMC manufactures soda ash using three different processes.

FMC’s proprietary sesquicarbonate “sesqui” processing method has been utilized by this facility since 1953. The sesqui process begins as trona ore is crushed and dissolved. The insolubles are separated and removed, and the trona is crystallized as pure sodium sesquicarbonate. Finally, these crystals are heated in calciners to produce soda ash.

FMC’s patented monohydrate “mono” production method differs from the sesqui process in that the order of processing is reversed. First the trona ore is heated and then it is dissolved. The insolubles are separated and removed, and the purified solution is sent to large evaporators where sodium carbonate monohydrate crystallizes out. Finally, the water is driven off to leave behind pure anhydrous soda ash crystals.

FMC’s newest production method utilizes patented technology to make soda ash from solution mined liquors. In this process the solution from the mine is first concentrated through evaporation. It is then reacted with lime to convert residual sodium bicarbonate to sodium carbonate. The carbonate goes through a two-step crystallization process to form first decahydrate crystals, and then monohydrate crystals. These are then calcined to produce soda ash.

FMC’s expertise in natural soda ash production enables our customers to span diverse end-uses. Soda ash is used in manufacturing glass containers, flat glass, fiberglass, chemicals, detergents and pulp and paper. Other applications include air and water treatment, mining, and petroleum production.

Applications Soda ash has been used in manufacturing for over 5,000 years. Ancient Egyptians recovered the product from dry lake-bed deposits or manufactured it by burning seaweed and other marine plants. This product was used to make glass ornaments and vessels. The Romans used soda ash for baking bread, making glass, and for medicinal purposes. Today, FMC supplies soda ash to a wide variety of industries.

GlassGlobally, about half of all soda ash is consumed by the glass industry. Flat glass for autos, homes and buildings, and container glass for consumer products are the two largest segments. Other products include lighting, glassware, screens for consumer electronics and solar glass. Soda ash reduces the melting temperature of the sand used in glass formulations and the alkali helps aid in the “workability” or forming of the glass article. FMC’s Grade 260 Dense Soda Ash particles are similar in size to silica sand, enabling the homogeneity of raw materials that is so important in producing a high quality finished product.

DetergentsSoda ash is widely used in soaps, detergents and other cleaning products. It is a good source of alkalinity for pH adjustment, a carrier of surfactants and dyes and an effective precipitating builder for removing hardness ions from water. In the detergent manufacturing process, soda ash aids agglomeration and may be used to neutralize the acid form of anionic surfactants. It enables easier conveying and ideal surfactant loading. Soda ash can also be hydrated to carry water as a filler and to enhance the storage and dissolving properties of the detergent. Soda ash is also an ideal high alkalinity builder for hard surface cleaning compounds and can be used as a source of alkalinity, buffering agent or water conditioner in mildly concentrated liquid formulations.

FMC is the only producer of two light density soda ash grades - Grade 100® and AbsorptaPlus®. These products find extensive application in the detergent segment due to their high absorptivity characteristics. Grade choice depends on the detergent manufacturing process and the surfactant level desired. Grade 100® soda ash is a standard in industrial and institutional formulating due to its absorptive properties and ideal bulk density. AbsorptaPlus® has increased absorptivity and advanced processing characteristics. ChemicalsSoda ash provides the sodium source for the manufacture of many materials including sodium percarbonate, sodium phosphates, sodium sulfate, sodium sulfite, sodium acetate, sodium nitrite, sodium silicate and sodium citrate. It is also used in the production of sodium bicarbonate (baking soda), which FMC manufactures as well. Soda ash can also be used as a functional substitute for caustic soda in applications such as pH adjustment, acid neutralization, sodium chemicals manufacture, and pulp and paper processing.

FMC pioneered solution mining used in both our Westvaco and Granger facilities.As the leader in trona mining and processing, FMC continues to develop innovative mining techniques and proprietary process equipment to provide an even more reliable and economical alkali supply.
