MHA binder has obvious effect on the strength and

A further study on adsorption interaction of humic

2015-2-1  Consequently, many investigations have been performed on developing novel binders as a substitute for bentonite. Modified humic acid (MHA) binder, extracted from the lignite or weathered coals in alkali liquor and authorized in China,has been proven as an effective binder for iron ore pellets. It is significant to identify the interaction mechanism of the MHA adsorbed onto the iron ore particles for

2017-4-12  Modified humic acid (MHA) binder consists of high molecular weight organic molecules and inorganic part. It is extracted from lignite coal with sodium hydroxide and used in pelletization of iron ore concentrates. Our previous study shows that MHA binder is also a potential binder instead of bentonite for pelletizing of fluxed hematite.

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.
