A new approach for SMR was developed for efficient iron recovery from iron ore tailings. • An iron concentrate with 58.67% Fe at an iron recovery of 57.82% was obtained. • Hematite and siderite were transformed into magnetite during the SMR process. • The SMR reactor showed good performances in terms of operation, control and product.

The research is aimed at study of the probable recovery of iron from the tailings of the Olcon mining company located in the north-western Arctic zone of Russia. Material composition of a sample from a tailings dump was analysed. The authors have developed a separation production technology to recover magnetite-hematite concentrate from the ...

A pilot continuous centrifugal concentrator was used to reconcentrate fine hematite from a high gradient magnetic separation concentrate to study the effect of feed volume flow rate, feed % solids ...

As shown in Table 1, Fe was the main recovery component with a content of 24.27%, and SiO 2 was the main impurity with a content of 60.39%. The analysis of Fig. 1 shows that hematite and magnetite are the main iron-bearing mineral in raw ore. Gangue mineral was mainly quartz. The dissociation degree and intergrowth relationship between …

As shown in Fig. 5 b, the hematite (Fe 2 O 3) in the high-silica concentrate disappears, and it appears in the iron-rich tailings after the S-HGMS process, consistent with the XRF result (Fig. 5 a). Fig. 5 c show the SEM micrographs along with the elemental mapping of the high-silica concentrate obtained under optimal superconducting …

Both froth concentrate and tailings were collected, separated from water, dried, weighed and analyzed Each flotation test was performed at least three times Both the average and standard deviation values are reported Since hematite and magnetite were together in the pulp product, the hematite recovery R was calculated using the following ...

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, …

Hematite, also spelled haematite, is a weakly magnetic iron ore with better floatability than magnetite and wide distribution.It is one of the most important raw materials for the extraction of iron. Its composition is complex. In addition to containing a small amount of magnetite, the impurity embedding of haematite has uneven particle size and …

Production of High Grade Iron Ore Concentrates Using hematite concentrate from tailings of mineral processing plant. concentrate has proven to be an flotation popular in the mineral processing industry Cleaner 1 367m x 14m Silica reduction from hematiteMineral processing plant technology Hematite separation process Hematite …

hematite content at the MGOK, the research was conducted along the following three lines: 1. Production of a high-quality hematite concentrate from initial tailings by reverse cationic flotation. 2. Reverse cationic flotation with iron pre-concentrate produced by gravity separation (spiral separators). 3.

The proposed technology allows recovering hematite concentrate with a hematite iron content of 54.5% and recovery of 75.4% from current tailings containing 5.2% of hematite iron. It was also shown that hematite concentrate can be recovered from stockpiled tailings using the separation technology based on the use of spiral separation.

A new approach for SMR was developed for efficient iron recovery from iron ore tailings. • An iron concentrate with 58.67% Fe at an iron recovery of 57.82% was …

The former mainly selects magnetite ore, and the latter is mainly used for sorting hematite, mixed iron ore and weak magnetic ore. 6.2 Magnetic separation – cation reverse flotation process The grade of iron concentrate increased from 65.55% to 38.89%, the silica content decreased from 8.31% to 3.90%, and the iron recovery rate was over 98.5%.

The current centrifugal concentrators do not continuously concentrate heavy minerals of large mass weight—for example, in the processing of iron oxides. A cyclone centrifugal separator is a new type of beneficiation equipment that has been developed on the basis of the principles of centrifugal separation and hydrocyclones. In this study, a …

Pre-concentration followed by magnetization roasting and magnetic separation process was well recognized to be very effective in recycling iron from iron ore tailings. An iron concentrate ...

A new approach for recovering iron from iron ore tailings … WebFeb 1, 2020 A new approach for SMR was developed for efficient iron recovery from iron ore tailings. • An iron concentrate with 58.67% Fe at an iron recovery of 57.82% was obtained. • Hematite and siderite were transformed into magnetite during the SMR process.

As shown, the recovery of the concentrate increased rapidly from 59.97% to 65.08%, while the grade of the concentrate decreased with the CMS content increasing from 0 g/t to 400 g/t. Moreover, when the CMS dosage was continually increased, the iron grade of the concentrate decreased rapidly and the recovery rate began to decrease.
