Assessment of Potential Material Reprocessing of Erdenet Mine Tailings
(German Mongolian Institute for Resouce and Technology, 2020-06-07) Azjargal Sengedorj; Munkhjargal Chimeddorj; Battsengel Baatar
The objective of this study is to define possible ways to reprocessing Erdenet mine tailings with potential metal recovery. These tailings have relatively high copper and molybdenum concentration (e.g. tailings III has Cu: 0.2-0.5%, Mo: 0.1-0.2% content), some of which are concerned as reusable deposits. But the measured concentration of metals does not have a homogeneous population over the whole tailings due to settling of the materials, reclamation of process water and drying of the materials, etc. The tailing facility is one of the largest in the world with a total area of 18.6 km2. Over 40 years of history of Erdenet processing plant, the tailing has been collected in the tailing dam and now becomes the biggest resource for research. The surface samples were taken from 5 different areas with various depths. Furthermore, physical analysis (Size distribution analysis) and chemical analysis (X-ray Fluorescence element analysis) were done. Based on physical and chemical characteristics, the possible applicable method to reprocessing tailing was investigated. As a result of this study, the possibility of using Erdenet Mine tailings has subjected to technical and economic considerations.
Beneficiation of Titanium Ores by Froth Flotation
(German Mongolian Institute for Resouce and Technology, 2021-05-25) Bat-Ochir Battumur; Munkhjargal Chimeddorj; Battsengel Baatar
In this thesis paper, the possibility of extracting titanium dioxide concentrate is examined on the deposit recently discovered in Mongolia. According to the drill core test performed by Aachen University, the deposit contains a considerable amount of leucoxene, which is the weathered product of ilmenite. In the past, many scientists studied how to improve the poor efficiency of conventional ilmenite collectors. Consequently, the use of lead and cupric ion activators and mixed flotation showed noticeable improvement in ilmenite floatability. Moreover, the pre-removal of magnetite from the titanium ore is proven to be a practical arrangement to achieve higher recovery in flotation. Based on these studies, the scheme for enriching titanium dioxide concentrate from the titanium ore sample is developed.

Rare earth metals are magic. The rare earth elements play key role in the expected growth of many emerging clean energy technologies. The next generation of wind and hydro power turbines, batteries, motors to power electric vehicles and fuel cells are example application. Moreover, the REE used for health, military defence and advanced communications including drug treatments,diagnostic techniques, MRI and visors protection, aircraft parts and GPS ,space based satellites and communication systems. Therefore, the developed countries are mostly used these elements. However, China are restricting rare earths exports to other countries because they are responsible for 97% global output. Therefore, I have chosen rare earth elements topic due to Mongolia has big number of resources and we could export our raw material to developed countries. We have interest to extract rare earth metals and exporting. Therefore, the rare earth metals study is developing in Mongolia.

(German Mongolian Institute for Resouce and Technology, 2018-06-08) Chinbayar Majaa; Munkhjargal Chimeddorj; Battsengel Baatar
Coal has traditionally been treated by gravity separation techniques, most suited to the cleaning of coarse coal (particles with diameter greater than 1.0 mm. Fine coal was generally discarded (Mohns, 1997). In 1950 M.King Hubbert calculated feature oil production rate. We all known as ‘Hubbert peak1 Same as this calculation in recent years has been a significant decreases in coal reserves. Especially higher grade coal deposits. The fine coal recovery has resulted recovery of tailings from traditional coarse coal cleaning process. Because of fine coal content in mineable coal is 35%, and for some reaches 60%.

The Industrial Revolution, which took place from the 18th to 19th centuries, was a period during which predominantly agrarian, rural societies became industrial and manufacturingdominated ones. Industrialization marked a shift to powered, special-purpose machinery, factories and mass production. Industrialization progressed by help of more and more natural resources to speed up productions. Since then mining industry plays significant transformation during the Industrial revolution time.
Investigation of rare earth elements (REEs) from coal and coal byproducts
(German Mongolian Institute for Resouce and Technology, 2023-05-14) Bold Khosbayar; Bayardulam Jamiyansuren; Battsengel Baatar
The use of coal fly ash (CFA) as a potential secondary source of rare earth elements (REEs) has gained attention of researchers recently due to its high REEs content. The aim of thesis is to investigate conventional physical separation methods, such as particle size analysis, magnetic separation and froth flotation, for the recovery of REEs from fly ash obtained from a commercial coal-powered plant. The amount of rare earth elements (REEs) present in the sample of coal fly ash was measured using a technique called inductively coupled plasma optical emission spectroscopy (ICP-OES). The findings of the quantitative analysis revealed that the total content of REEs in the coal ash was 416.7 parts per million (ppm).Experimental results showed that flotation was effective in improving the recovery and upgrading of REEs depending on the pH condition of the pulp. The highest REEs recovery 71.72% was achieved at pH 12, while the best grade upgrade 456.44 ppm was achieved at pH 10. However, magnetic separation tests showed that most REEs ended up in the tailings. The performance of various beneficiation methods varied significantly in this study. Overall, it was concluded that physical separation methods could be used to recover REEs from coal fly ash before further processing through hydrometallurgical methods. These findings have important implications for the development of sustainable and costeffective processes for the extraction of REEs from alternative sources, such as coal fly ash.

Rare earth elements (REE) are considered critical raw materials essential for numerous clean technologies. As the discrepancy, their supply and demand increase globally. It is conceivable to recover REEs from secondary sources in order to close the gap. The coal, fly ash, and bottom ashes are collected from Baganuur Mining, Thermal Power Plant IV, and Baganuur Thermal Plant, respectively. The TESCAN Integrated Mineral Analyzer (TIMA) and X-ray diffractometer (XRD) were used to characterize the mineralogy of coal, fly ash, and bottom ashes and further investigation of REE associations and its mineral. It was demonstrated that rare earth minerals still exist in coal fly ash and are associated with metal oxides. The quantity of REEs in the coal sample was determined by using the inductively coupled plasm-mass spectrometry (ICP-MS) technique. The quantitative analysis result shows that the total REEs content in the coal ash was 414 parts per million (ppm). It was revealed that REEs are concentrated in fine non-magnetic particle size, and the froth flotation process is most effective at a pH=10. Using the physical separation method, the REEs in the coal fly ash was slightly enriched from 414 to 456.44 ppm. Thus, hydrometallurgical leaching is advised to evaluate the possibility of REEs recovery from secondary sources.

Study on solid particles and chemical elements, which affect crud formation, in pregnant solution of low-grade copper ore leaching
(German Mongolian Institute for Resouce and Technology, 2021-05-28) Indra Batbileg; Battsengel Baatar; Bayardulam Jamiyansuren
This work in this thesis aimed to understand and characterize the elements of crud. Furthermore, to have an option to minimize crud formation in low-grade copper ore pregnant leach solution. The Solvent Extraction operations often suffer from increased purification complexity due to crud formation at the interface of aqueous and organic phases. Crud at the interface of SX generally comprises solid particles that are Al, Mg, Fe, and Si in the pregnant leach solution. Ion exchange resins have been using an option to increase the separation efficiency of the selected copper metal ions from the solution before the SX process. There is a fact, organic solvent consumption decreases by 63% and diluent by 86% after applying the Ion Exchange process in the Buchim copper plant. It directly reduces plant footprint and crud formation in the SX pond. Therefore, capital and operational expenditures on these factors are minimized.
