In this work, a study on the dynamics of transformation from hematite (α-Fe2O3) to magnetite (Fe3O4) by following two solid-state reaction methods is carried out. One of the procedures consists of a thermal treatment under a 20% H2 and 80% N2 atmosphere at 375°C, whereas the second method involves a planetary ball mill to induce the transformation. The phases …

We present the process of synthesis and characterization of magnetite-maghemite nanoparticles by the ball milling method. The particles were synthesized in a planetary ball mill equipped with vials and balls of tempered steel, employing dry and wet conditions. For dry milling, we employed microstructured analytical-grade hematite (α-Fe2O3), while for wet milling, we …

Ball Mill Results Prior to any pilot ball mill work, one Levin test was completed on the secondary grind feed shown in Fig. 6. The Levin test is a fine-feed substitute for a standard Bond Grinding Work Index test and it uses sequential open circuit milling passes applying a known energy at each pass. The results from

ZRP orebody contains approximately 40.8% magnetite with a 70:30 magnetite to haematite ratio (Kumba Iron Ore, 2013). The implications of the lower magnetite to haematite ratio of this bulk sample on the pilot plant mass yield will be highlighted and discussed under the mass balance results. The Bond Ball Mill Work Index (BWI) was determined

elongation values of magnetite particles for the ball and rod mill products are 1.457 and 1.538 respectively, and the roundness values are 0.949 and 0.933 respectively. Therefore, in this size fraction, the elongation value for the rod mill products is higher than for the ball mill products. Even though the rod mill products have a higher ...
