Two ground magnetometer surveys over iron ore deposits in Jamaica are described and the results of the observations interpreted. An improvised but economical technique is used to measure the main magnetic properties of ore samples obtained from surface exposures, and a suitable statistical analysis is applied to determine the significance of these observations.Get A Quote
The magnetic properties of iron ores were improved at 700 and 800C, but the presence of wustite lowers the magnetic properties compared to 600C. Increasing temperature up to 900C enhances the magnetic properties of iron ore due to the presence of magnetite and metallic iron which are classified as strong magnetic materials.Get A Quote
Although the majority of current steel production is supported by iron ore sourced from high-grade haematite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed. There is a rich and long history of magnetite ore processing in.Get A Quote
