The magnetic fraction was identified as being predominantly zinnwaldite (Siame and Pascoe, 2011). 3.3. Sensor-based sorting. Sorting is a technique used to separate materials based on various properties including colour, density or electromagnetic properties. Ore sorting can be done by either manual hand sorting and automated mechanical sorting.
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. ...

The BHQ ore sample was obtained from one of the iron ore mines of Hospet located in the Karnataka state of India. The chemical analysis of the BHQ sample is given in Table 1.The sample was crushed to below 10 mm size, and a representative sample was drawn to generate hematite and magnetite pellet feed concentrates through the techniques of …
China understood magnetite and was happy to pay for it; Australia didn't understand magnetite, but it soon would. Go deeper: Special report - Investors and physical hedgers flock to iron ore. Unfortunately, the story of Karara is emblematic of Australia's magnetite ore industry, which to date has been a major disappointment.
Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon of 54.25% was used as …
