ORE FINE AGGLOMERATE TO BE USED IN SINTERING PROCESS AND PRODUCTION PROCESS OF ORE FINES AGGLOMERATE

摘要

Discloses a feldspar aggregate to be used in a sintering process wherein the feldspar aggregate is formed by a mixture of feldspar particles and flocculants wherein the particles have a diameter of from 0.01 mm to 8.0 mm. The process of producing minute aggregate of aggregates comprises the steps of using volcanic rock particles having a particle size of less than 0.150 mm; Mixing the colloidal particles with a flocculant at a ratio of about 0.5 to about 5.0 mass percent sodium silicate; Forming wet particles having a diameter of from about 0.01 mm to about 8.0 mm upon addition of water; And drying the wet particles at a temperature varying from about 100 캜 to about 150 캜 to form dry particles resistant to mechanical effort and urea.
