Quality Magnetite D.R.I. Fines, also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gasses. Direct reduction refers to processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. The product of such solid state processes are called direct reduced iron.

Quality Magnetite Hematite Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together in a mixer and fed to balling disks or drums to produce green pellets of size typically about 9-16mm.

Quality Magnetite Granulated Slag by-product is formed in smelting, welding, and other metallurgical and combustion processes from impurities in the metals or ores being treated. Slag consists mostly of mixed oxides of elements such as silicon, sulfur, phosphorus, and aluminum; ash; and products formed in their reactions with furnace linings and fluxing substances such as limestone. Slag floats on the surface of the molten metal, protecting it from oxidation by the atmosphere and keeping it clean. Slag forms a coarse aggregate used in certain concretes; it is used as a road material and ballast and as a source of available phosphate fertilizer.

Refractory Minerals REF-Bond MP2 QD (MP2 QD) is used in refractory applications as well as specialty cementing. This material has been used commercially for decades in dental and cement applications. Typically Mono Magnesium Phosphate was dried driving off physical water and leaving the chemically bound water. Drying MP2 drives up the cost and makes it very hygroscopic. It was found that a more stable material could be produced by not driving off the physical water. This brought down the cost so that it could be considered for bulk refractory applications.
