Adsorption of lignite humic acid onto magnetite

Modified humic acid (MHA) binder based on lignite humic substances is a novel sort of promising organic binder for iron ore pellets. Humic acid (HA) is one of the main ingredients of MHA binder. Pure HA was firstly isolated from lignite and then adsorption of HA onto magnetite particle surface was investigated.

Effect of modified humic acid binder on pelletisation

2015-4-12  A modified humic acid (MHA) binder was tested as a substitute for bentonite to prepare qualified specularite pellets. The results show that there is stronger chemisorption between organic functional groups in MHA binder molecular and specularite particles, improving the green pellet strength. MHA binder has obvious effect on the strength and microstructure of preheated pellets due to the ...

Review of briquette binders and briquetting

2018-2-1  The results have shown that a humic acid solution containing 10.75 wt% nitrogen was obtained with 88.2 wt% recovery from Elbistan lignite. When coal-derived humic acid was used as a binder, production of briquette is being water-resistant and durable performance.

Pelletization Using Humic Substance-based Binder:

2017-1-31  Humic substances exist widely in lignite coal as high molecular weight organic molecules. They can be used as binders in iron ore pelletization mostly in the form of salt, such as sodium humate and amine humate via extraction from lignite coal. It is worth determining if lignite can be used as a binder without extraction.
