The Abu Tartur phosphate deposit is characterized by the presence of ferriferous dolomite, containing 60 to 70% of MgO, which allows the use of magnetic separation to reduce the MgO content of certain fractions. ... Data of wet beneficiation of Abu Tartur phosphate; grinding to 1500 μm, screening at 210 μm and magnetic …

4. Conclusions. Abu Tartur phosphate rock can be beneficiated by leaching it with dilute acetic acid. This is due to the fact that dilute acetic acid used in leaching has the ability to react with the calcium carbonate impurity found in the phosphate rock while its attack on the tricalcium phosphate is small.

Abstract. The present paper focuses on the phosphate-bearing deposits that represent. promising geologic resources for mining and su stainable development in central. Egypt. Phosphates are ...

Section snippets Geologic setting. Abu Tartur is a plateau of approximately 470m–550 m altitudes above sea level. It forms one of the main geographical features in the Western Desert in Egypt, covering a vast area of 2000 km 2 that lay between Kharga oasis and Dakhla oasis depressions to the east and west, respectively. The study area is …

The Abu Tartur phosphate deposit is characterized by the presence of ferriferous dolomite, containing 60 to 70% of MgO, which allows the use of magnetic separation to reduce the MgO content of certain fractions. ... It can be noted that dry magnetic separation has already been used on a laboratory scale, for Abu Tartur …

Report on Abu Tartur Phosphate Rock Beneficiation. Almodather Awad. This report was written and submitted as a task in the course work of a course on fertilizer technology, given in the 2019-2020 academic year, at …

This enabled the beneficiation of Abu-Tartur phosphate rejects (21.8 wt% P 2 O 5 & 1.8–8.0 wt% MgO), resulting in valuable concentrate assaying 29.5 wt% P 2 O 5 and 0.6–1 wt% MgO (Yehia et al., 2001; Abouzeid et al., 2009). However, the flotation processes were no longer practiced at Abu-Tartur mine due to the scarcity of water in …

Abstract The beneficiation of phosphate ores containing carbonate gangue by conventional techniques such as physical separation methods or flotation is very ... the amenability of upgrading the reject generated from beneficiating Abu-Tartur phosphate ore by magnetic separation was investigated by two methods: leaching with acetic acid ...

Solid and liquid wastes associated with the phosphate mining and beneficiation activities at Abu Tartur phosphate mine were collected from the tailing pond. Characterization methods were used to assess the physical and chemical properties that may.

As a result, the high-grade ores are continuously been depleted, and beneficiation of lower grades seems to be an urgent commitment. In this script, the term commercial phosphorite designate those containing above 27% P 2 O 5 and it is medium-grade if containing <27 and >20% P 2 O 5. The low-grade phosphate rocks are those …

The phosphate resources in Egypt alone exceed 3 billion metric tons. Two-third of these three billions occur only in the Abu-Tartur area. Among the phosphorite deposits in Egypt, the phosphorites of the Abu-Tartur area are characterized by high contents of iron ranging from 3 % to 7 % with an average of 5 %.

Egyptian Abu Tartur high-grade phosphate ore in the size range of 38–210 mm. A concentrate assaying 31.2% P 2 O 5 with a recovery of 70% was obtained through the removal of dolomite gangue

The dissolution kinetics of the Abu-Tartur phosphate rock using dilute hydrochloric acid has been investigated. The influence of acid concentration, liquid/solid ratio, particle size and temperature was studied to explore the dissolution kinetics of phosphate rock. It was found that the leaching rate increases with increasing the acid concentration, liquid/solid …

Solid and liquid wastes associated with the phosphate mining and beneficiation activities at Abu Tartur phosphate mine were collected from the tailing pond. Characterization methods were used to assess the physical and chemical properties that may impose environmental and/or human health risks. The hydraulic conductivity of the sampled …

The conventional phosphate beneficiation process. As mined, the phosphate and sand particles are embedded in compacted mud, or "clay-balls". Before separation can begin, all the particles must be liberated from the matrix of mud. The very first unit operation in the beneficiation process is to disaggregate the various particles; this ...

Effect of formic acid concentration on the % P2O5 in the treated rock As shown in figs. 1, and 2 the % P2O5 in the treated rock increases by increasing the formic acid concentration up to 0.6M in case of partial acidulation for 30 minutes and up to 1.2M in case of partial acidulation for 15 minutes.A further increase in the acid concentration ...
