Extraction of Sc from Sc-Bearing V–Ti Magnetite Tailings

2021-4-21  In this study, a magnetic separation–shaking table gravity separation process was used to treat Sc-bearing V–Ti magnetite tailings, and the Sc2O3 content in the Sc concentrate was enhanced from 0.0039 to 0.0061%. The majority of the Sc in the Sc concentrate originates from augite, hornblende, and aluminosilicate.

Synthesis of magnetite powder from iron ore tailings

2010-7-26  We conclude that it is possible to prepare a good quality magnetite from iron ore tailings, which are waste materials of the iron ore industry. The required composition of an Fe(III)/Fe(II) ratio of 2:1 for the preparation of magnetite can be obtained from the acid extracted FeCl 3 solution via metallic iron

Effect of ultrasonic treatment of magnetite slurry on the

The investigations showed that preliminary treatment of finely comminuted iron ore (slurry) with ultrasound prior to the magnetic separation improved the technological indicators of the enrichment (when the material was treated for 5 min the iron content in the concentrate was increased by 1.13%; as the duration of the treatment is reduced, the increment of iron content in the concentrate decreases, amounting to 0.44–0.30%, with slight change of iron content in the tailings).

Overall utilization of vanadium–titanium magnetite

2020-5-4  In order to improve the fluidity and dispersion of the ceramic slurry, the vanadium–titanium magnetite tailings were first dried in an electric oven at 105 °C for 24 h and then smashed to pass through a 180 mesh sieve.

The influence of seawater on magnetite tailing rheology

2019-1-15  Abstract. It is well known that seawater affects mineral beneficiation, especially in the presence of fine particles. In the present paper, the effect of seawater fraction on the rheology of unflocculated fine magnetite tailings has been studied. Slurry data has been interpreted as both Bingham and Herschel-Bulkley fluids.

Effect of magnetic-field heat treatment on directional

2019-4-3  It was verified that Fe ions can destroy the glass network structure in these glass ceramics to promote crystallization. The production of Fe 3 O 4 magnetite in a second phase and the gradual increase in Fe 3 O 4 magnetite content was caused by an increase in the Fe 2 O 3 content added in the glass ceramic. The results showed that the magnetite phase grew in the form of dendrites, which was

Maximizing the recovery of fine iron ore using magnetic

2012-4-4  The results show that there is about 25% magnetite by mass in the tailings sample with the main gangue minerals being quartz, feldspars, mica, and chlorite. Therefore, assuming adequate liberation, the recovery of the magnetite by magnetic separation was considered to be viable. The small amount of haematite present was considered as
