WhatsApp: +86 18203695377In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.
WhatsApp: +86 18203695377For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

In addition to its Scope 3 decarbonization strategies, Vale has set a goal of reducing Scope 1 and 2 emissions by 33% by 2030 with 4 billion6 billion in investments.
WhatsApp: +86 18203695377Figure 3 shows a comparison of the IEA and WSD views and the related iron ore demand of between 400 and 600 mt by 2050, compared to about 160 mt in 2019. From the quantitative perspective, iron ore supply should not be an issue, with BF iron production falling from just under billion tonnes in 2019 to 665 mt by 2050 per IEA's SDS (see Figure 1).
