Hematite is the iron ore which occurs most frequently and in the greatest quantities. According to its genesis, it is available in

On the basis of pelletizing process, the iron ore pellets market is segmented into grate kiln and straight travelling grate. In 2021, the …

and minerals with pelletizing As high-grade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest ...

Its annual capacity will be 5 million tonnes of iron ore pellets. About two thirds of the global pellet production derives from Outotec's environmentally sound traveling grate pelletizing process. Technology enables large capacities with low operational costs. "We are happy with the continuation of the traveling grate story in China.
