Binder composition for cold forming metal ore pellets
A patent application (Publication Number: US20240035111A1) discloses a binder composition designed for the cold forming of metal ore pellets. The composition includes a hydraulic binder component with specific particle size characteristics and chemical composition, such as a CaO content of >62.5 wt.-% and a C3S content of >60 wt.-%. Additional components like alkanolamines and gypsum are included in specific amounts to enhance the binding properties. The binder composition may also contain various additives like calcium aluminate cement, iron sulfate, and superplasticizers to further improve pellet quality.
Furthermore, the patent application describes a method for producing metal ore pellets using the aforementioned binder composition. The method involves mixing finely ground ore with the binder composition, pelletizing the mixture, and optionally adding a carbon source. The pellets are then cured at specific temperature and humidity conditions to achieve the desired properties. Different pelletizing techniques, such as spreading the binder composition as a powder or using agglomeration devices, are outlined in the method. The resulting metal ore pellets exhibit improved strength and durability, making them suitable for various industrial applications. Overall, the patent application provides a comprehensive guide for formulating binder compositions and producing high-quality metal ore pellets efficiently.
