Liaoning dongda Powder Engineering Technology Co.,Ltd. Introduction to Hematite Magnetic Calcination Process: The rich iron ore resources are limited in China, so the hematite separation becomes a major engineering issue in the mineral separation technical field.
Hematite, also spelled haematite, is a weakly magnetic iron ore with better floatability than magnetite and wide distribution. It is one of the most important raw materials for the extraction of iron. Its composition is complex.
The hematite separation process mainly involves various methods to extract valuable minerals from the ore, including crushing, grinding, magnetic separation and flotation. It is suitable for processing hematite with complex …
In drilling operations, minimising friction is paramount for equipment longevity and operational efficiency. Hematite powder, with its lubricating properties, forms a thin, protective layer on drilling equipment surfaces. This reduces friction, enhances lubrication, and ultimately extends the lifespan of critical drilling components.
FE 601 is a high purity, very fine hematite (Fe2O3) powder. They disperse and wet easily, and have good suspension properties.
To explore these issues in detail, hematite was mixed with gangue minerals of various size fractions or species, as detailed in Table 1. For adhesion between fine particles, mixtures of hematite and quartz particle sizes (38–150 μm, 13–38 μm, and 0–13 μm) were tested to evaluate the impact of particle size on separation performance.
The detailed chemical compounds of the cement, fly ash, silica fume, and hematite powder are presented in Table 1. The X-ray diffractometer (XRD) results for the hematite powder are shown in Fig. 1. We determined that the main oxide in the hematite powder was Fe 2 O 3, accounting for 60.07% of the total.
