crushing ferromanganese

284 MINENALOGICAL NOTES

2007-4-3  Crushing ferromanganese oxid.es from deep-sea. nodules at,77'K in a pool of liquid nitrogen resulted in improved X-ray powder photographs. This tech-nique may reduce orientation effects in mounting, wiII inhibit oxidation during crushing and in zubsequent storage, and may have application to other water-bearing minera.ls.

Estimation of degree of liberation in a coarse crushed ...

2008-7-2  Specific gravities of the cobalt-rich ferromanganese layer component were lighter than those of the nuclei or substrate rock. Jig tests of the 1 to 4 mm, and 0.5 to 1 mm size fractions were carried. Except the one sample, purities of cobalt-rich ferromanganese layer component were higher than 0.8 when the recovery values are about 0.9.

Nitriding of Medium Carbon Ferromanganese Alloy in

2013-12-24  Ferromanganese alloys are widely used as additive in steelmaking process. During crushing of ferromanganese alloy to suitable sizes to be directly used in steelmaking process, more than 5% of the alloy is produced in fine size. This fine size alloy must be retreated to be suitable for utilization.
