Title: PROCESS FOR PRODUCING A CERAMIC PROPPANT FROM IRON ORE AND/OR EXPLOITATION TAILINGS THEREOF AND/OR PROCESSING WASTE THEREOF BY FINE AND ULTRAFINE PARTICLE AGGLOMERATION - PCF
Abstract:
The present patent document relates to products and processes for producing a ceramic proppant from iron ore and/or exploitation tailings thereof and/or processing waste thereof and/or fine and ultrafine particles of other origins with similar properties, by agglomeration of said materials and subsequent heat treatment, resulting from the combination of distinct technologies, previously used for other purposes, capable of producing a ceramic material, transforming the materials, including waste and tailings from other processes, into products with high added value, in addition to, evidently, reducing the impact of mining activity, with improved use of mineral resources. Such practice, in the future, could allow waste and tailings that end up in new waste dams and heaps to be reduced, as well as structures such as heaps and old dams to be recovered.
