Ore fine agglomerate to be used in sintering process and production process of ore fines agglomerate

摘要

An ore fine agglomerate to be used in a sintering process is disclosed, wherein the ore fine agglomerate is formed by a mixture of ore fine particles and an agglomerating agent, and wherein the particles have diameters between 0.01 mm and 8.0 mm. A production process of ore fines agglomerate is disclosed comprising the steps of using ore fine particles with a granulometry lower than 0.150 mm, mixing the ore fine particles with an agglomerating agent in a ratio of 0.5 to 5.0% by mass of sodium silicate, forming wet particles with diameters between 0.01 mm and 8.0 mm with an addition of water, and drying the wet particles at a temperature varying from 100° C. and 150° C. to form dry particles that are resistant to mechanical efforts and the elements.

1. An ore fine agglomerate to be used in a sintering process, comprising:
ore fine particles, an agglomerating agent comprising sodium silicate, and microsilica as an additive in a range of 0.3% to 1.0% by mass, wherein a ratio of the ore fine particles and the agglomerating agent is about 0.5 to about 5.0% by mass of the agglomerating agent, and wherein the ore fine agglomerate has a diameter between about 0.01 mm and about 8.0 mm, and has cured at a temperature of about 100° C. to about 150° C. in about 3 to about 20 minutes.
