Lime-based binders - sometimes including special clays - increase sinter plant productivity. ... Oily mill scale is a ...
The intraday most-trade iron ore contract has surged by more than 9% as the time of this writing. On the other hand, however, coke prices have been falling for seven consecutive rounds, and the ore prices are also at a low level, restoring part of the steel mills' profits. Hence, ore prices will gain some support in the short term.

Iron ore has had a wild year as a first-half demand boom was quashed by China's squeeze on real estate finances that drove a fall in construction activity, as well as a government push to curb pollution and emissions. Steel output slid to the lowest since 2017 in October, and Singapore futures plumbed an 18-month low earlier in November.
rect reduction of iron ore for the manufacture of iron and steel is preferred because it does not require coke manufacturing and has fewer environmental impacts. Wherever feasible, pel-letizing should be given preferences over sinter-ing for the agglomeration of iron ore. The following pollution prevention measures should be considered.
Our robust pug mills (paddle mixers) and rotary dryers are also frequently relied upon for processing steel by-products in the form of dust and scale in order to liberate iron ore. Rotary dryers may also be used in ore drying applications. We can also supply briquetters for briquetting sponge iron and hot briquetted iron (HBI).
