: Stabilization of iron ore tailings with cement and ...

2020-5-23 Test results reveal that the introduction of cement/bentonite to iron ore tailings requires higher water content for optimum compaction and results in lower dry density. The addition of bentonite increases the unconfined compressive strength (UCS) very little, whereas there is a great strength enhancement for tailing-cement mixtures, particularly after a period of moist curing.

2002-7-1 Bentonite is a significant cost item in iron ore pelletization, and also contributes undesirable amounts of silica to the finished pellets. If the binding effectiveness of bentonite is increased, it will be possible to reduce the bentonite dosage, resulting in significant cost savings while producing higher quality, lower silica pellets.

2008-6-20 IIron ore pelletisation (IOP) uses bentonite as a binding ron ore pelletisation (IOP) agent, and is added to dry iron ore to form pellets. Sodium bentonite is preferred for its excellent plasticity, dry bonding strength and high mechanical strength at high temperatures. Both sodium and calcium bentonite is used in ffoundry oundry

2017-6-22 A higher methylene blue absorption value indicates that the bentonite has higher absorptivity, water absorption capacity, and larger swelling volume. Methylene blue absorption, swelling volume, montmorillonite content, and water absorption are important indices for evaluating bentonite quality.

2003-2-19 Effect of activated bentonite addition on the productivity of the high barite iron ore concentrate green pellets. The average drop number of green pellets increases while adding 0.5–1% activated bentonite and 11–13% water, Fig. 10. However, further addition of activated bentonite decreases the drop number.

: Characterization of Humic Acid Modified Bentonite

Abstract. Anew kind of iron ore pellet binder named humic acid modifying bentonite (HA-MB) has been developed by the author’s group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HA-MB binder. In this study, the detection of the characterization of HA-MB was ...

The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing. Bentonite adds unwanted silica to the final concentrated iron ore product. Excess silica from bentonite addition has been calculated to consume approximately 2.4 MJ of additional energy during the production of one metric ton of pig iron.
