The present patent document refers to the products and processes of Ceramic Proppant production from iron ore and/or sterile from its exploitation and/or tailings from its beneficiation, and/or fine and ultra-fine particles from other sources with similar properties, by agglomeration of these materials, and subsequent heat treatment, resulting from the combination of different technologies, previously used for other purposes, capable of obtaining a ceramic material, transforming the materials, including waste and sterile from other processes, into high value products, and reducing the impact of mining activity, with the best use of mineral resources. In the future, this practice may allow for the reduction of waste and tailings disposal in new dams and piles, as well as the resumption of structures such as piles and old dams.
CERAMIC PROPPANT PRODUCED FROM IRON ORE AND/OR STERILE FROM ITS EXPLOITATION AND/OR TAILINGS FROM ITS BENEFICIATION, or similar materials, characterized by the production of ceramic pellets and mini-pellets, which have high mechanical resistance to handling and function as fracture support agents.
PROCESS OF PRODUCTION OF CERAMIC PROPPANT FROM IRON ORE AND/OR STERILE FROM ITS EXPLOITATION AND/OR TAILINGS FROM ITS BENEFICIATION, or similar materials, THROUGH AGGLOMERATION OF FINE AND ULTRA-FINE PARTICLES, TO FORM PELLETS AND MINI-PELLETS, characterized by wet mix of fine and ultrafine particles, with or without the addition of predefined amounts of binder, basic and energy oxides, followed by agglomeration process, for pellet and mini-pellet formation, which after undergoing a specific heat treatment have high mechanical resistance to handling.
