Abstract. Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increased ...
To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction of iron ore (DRI) needs to be applied to stay competitive and ...
The use of iron ore tailings (IOT) is a trend for the future of mining. The adoption of alternatives that minimise the disposal of natural resources and add value to production processes strongly ...
With the increasing demand for mineral resources, there is an inevitable trend to carry out deep prospecting in existing old mines to find a second or even third mining space. Deep prospecting is also an affordable and practical way to prolong the lives of mines and provide a sustainable supply of mineral resources. The magnetic survey is …
