Bulk Materials We Ship Worldwide
IMI, along with its partners and affiliates, sells and ships over 13 million metric tons per year of natural gypsum, bauxite, iron ore and by-products, cement, clinker, coal, petcoke, and slag.
Natural Gypsum is a sulfate mineral compound of Calcium Sulfate Dihydrate. It has a wide variety of uses – primarily for plaster/wallboard and cement production, but also as a soil conditioner and fertilizer, in surgical splints/casting models and in impression plasters in dentistry.
Natural Gypsum is IMI’s flagship product with over 3 million metric tons sold each year. With long-term exclusive contracts with mines and quarries in Europe, Latin America and the Middle East, IMI is able to service a wide range of regions from the US East Coast to North Coast South America, India and Africa.
Synthetic gypsum (Syngyp), also called flue-gas-desulfurization (FGD) gypsum, is a by-product of coal-fired power generation. Syngyp is produced through FGD scrubbers that remove and significantly reduce sulfur emissions from the flue gases of coal fired power plants.
Chemically, Syngyp is nearly identical to virgin natural gypsum and is utilized in all of the same applications. IMI, through its partner Synthetic Materials LLC (SYNMAT), processes and markets over 4 million tons of Syngyp annually. SYNMAT is the largest processor and marketer of Syngyp in the US, operating at over 10 different generation facilities in the Mid-West and Mid-Atlantic US.
Bauxite is an aluminum ore and is the raw material in aluminum production. Typically, bauxite is classified in terms of its intended application: metallurgical, chemical, cement, etc. Bauxite is composed mainly of the minerals gibbsite Al(OH)₃, boehmite y-AlO(OH) and diaspore α-AlO(OH), with iron, clay and silica also present.
IMI markets approximately 500,000 MT of bauxite annually specifically for cement applications in North and South America.
Iron Ore/Iron Fines
IMI, in partnership with the Diproinduca Group, sells a wide range of products used as raw materials within the steel industry, including Iron Ore, Mill Scale, Direct Reduced Iron fines (DRI C), HBI and Oxide Iron fines. Our products range from 55% to 80% total Fe content, catering to a vast array of specific requirements by enabling the use of lower spec, lower cost materials in Sinter feed blends, thus improving the overall cost structure of our end users.
We deliver over 1 million tons of iron related materials per year, sourced mainly in North America, the Caribbean and South America and destined for China, Korea, Mexico and European markets. Our shipments range in size from Handysize to Panamax, depending on the product and port capabilities at origin or destination. Most of IMI’s sales are CFR, ensuring proper control and service throughout the entire supply chain.
IMI, together with our partners, have developed and improved the techniques and procedures to safely ship and transport certain iron products classified as dangerous goods for seaborne transportation.
Cement is primarily used in construction for the production of concrete and mortar, and is characterized as either hydraulic or non-hydraulic. Hydraulic cements (e.g. Portland cement) harden when mixed with water. The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble. Non-hydraulic cements (e.g. lime and gypsum plaster) must be kept dry in order to retain their strength.
IMI sources cement from first class producers in Asia, Europe, the Middle East and the Americas. Our cement is primarily sold in bulk, however we also sell bagged cement using either producer’s or buyer’s artwork.
Clinker is the main ingredient used in the manufacture of Portland cement. Clinker is formed in lumps or nodules, usually 3-25mm in diameter, by sintering limestone and alumino-silicate (clay) during the cement kiln stage. Clinker is ground in a mill, usually with gypsum, to produce Portland cement. It can also be ground with slag, pozzolan, and silica to produce special types of cement.
Under dry conditions, clinker can be stored for several months without significant loss of quality. As a result, and considering its relative ease of handling, clinker is traded internationally in large quantities using mainly bulk carrier vessels.
IMI sources its clinker from reliable producers in Asia, the Middle East, Europe, the Caribbean and the Americas. IMI sells clinker to cement grinding operations in the Americas, the Caribbean and Africa.
Petroleum coke, or petcoke as it is commonly known, is a by-product of petroleum refining. Petcoke refers to all types of carbonaceous solids obtained in petroleum processing which includes green (raw), calcined and needle petroleum coke. Petcoke is used in many applications, including electrodes and anodes. It is also used as a fuel in the cement, metal and brick industries.
As a fuel, petcoke offers high calorific value properties at a competitive price, making it a very attractive energy substitute for thermal coal.
IMI sources both high and mid-sulfur petcoke from petroleum refiners in the US Gulf and Venezuela for delivery to customers in South America, the Caribbean, Europe, India and China.
Coal is a combustible black or brownish-black sedimentary rock normally occurring in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, with smaller quantities of sulfur, oxygen and nitrogen. Coal is primarily used as a solid fuel to produce electricity and heat through combustion.
IMI sources coal from first-class operations in Colombia, Venezuela and the U.S., and is developing additional sources in South Africa and Asia. Our main markets are the cement industries of South America, the Caribbean, Europe, India and China.
Granulated Blast Furnace Slag
Slag is a non-metallic by-product of the steel-making process. It is converted to granulated blast furnace slag (GBFS) or ground granulated blast furnace slag (GGBFS) by quickly cooling molten slag with industrial water or air. IMI sources GBFS and GGBFS in Europe and Asia for delivery to customers in the cement industry in South America.
