Investigations on how the froth height is influencing the flotation of ultrafine particles using the newly developed separation apparatus MultiDimFlot
(German Mongolian Institute for Resouce and Technology, 2022-05-08) Nyamjargal Erdeneduvchir; Thomas Hollenberg; Martin Rudolph
Flotation is a separation process that is based on differences in the surface wettability properties of materials. Hydrophobic particles adhere to air bubbles and create particle-bubble aggregates that rise in suspension and form a froth layer, whereas the hydrophilic particles sink and remain in the pulp. The flotation process is widely applied in the separation of fine particles with a particle size range between 10 µm and 200 µm. However, the flotation of ultrafine particles (x < 10 µm) is facing challenges and unwanted ultrafine gangue particles have a high probability of being entrained, which reduces the quality of the product.
Assessment of wind energy resources of Mongolia
(German Mongolian Institute for Resouce and Technology, 2022-05-16) Naranzul Bayasgalan; Gantuya Ganbat; Odontungalag Dorjsuren
This study assessed the wind energy potential in Mongolia by analyzing wind speed data collected from 69 stations across the country. The data was categorized by region and analyzed using the Weibull distribution to determine the monthly mean wind speed and wind power density. Additionally, the study evaluated the potential reductions in the usage of CO2, water, and coal that could be achieved through the selection of wind turbines. To visualize the results, maps of wind power density and mean wind speed were created using a GIS program. Overall, this study provides valuable insights into the potential of wind energy as a sustainable and environmentally-friendly energy source in Mongolia. Wind speed data were collected from 69 Wind Measurement Towers (WMTs) over the course of one year. The WMTs recorded wind speed measurements every three hours throughout the day at a height of 10 meters. The Gobi areas and east Mongolia have potential wind speed to build wind farms compared to Khangai and West Mongolia.

Identification of Potential Location of Pond Sites for Irrigating Agriculture and Forestry Land Based on Watershed Analysis Using GIS
(German Mongolian Institute for Resouce and Technology, 2023-05-01) Enkhjargal Sodnomdarjaa; Enkhjargal Sodnomdarjaa; Gantuya Ganbat
The identification of potential locations for pond sites plays a crucial role in sustainable water resource management for irrigated agriculture and forestry land. This study focuses on utilizing watershed analysis techniques in combination with Geographic Information Systems (GIS) to identify suitable locations for constructing ponds. The objectives of the study are to assess water availability, identify suitable sites, and recommend areas for afforestation that uses near water sources. In this study, Watershed and Stream Network Analysis were done in the Kherlen Soum area in Khentii Province. Also using the ArcGIS program some additional analyses such as hillshade, slope, and basin delineation. Using the stream network analysis with the cadastral map of Kherlen soum and setting 3 criteria we determined the potential pond locations. After determining the potential pond sites we recommended 4 types of areas for the afforestation of the national movement of “Billion Tree” in Kherlen Soum. Recommended 4 types of areas are Unirrigated Self-Growing Tree Areas, Irrigated Growing Tree Areas, Forestation areas of Old Farmlands, and Kherlen River Irrigated areas. Using the Mongolian National Standard for Environment and Re-vegetation of destroyed land we estimated the standard for planting in one hectare as 722 units of trees and bushes. It will be a reserve forestation area for approximately 80 million units of trees and bushes by our rough calculation.

Optimizing Excavator Tooth Selection for Khuut Coal Mining
(German Mongolian Institute for Resouce and Technology, 2023-05-01) Galbadrakh Gankhuyag; Thomas Hollenberg; Nyamdulam Renten
Nowadays, many of the technological advancements in engineering today rely on minerals like copper, gold, and coal. The mining industry is important in the development of society and these technological phenomena. Excavators are mostly used tools to extract those minerals which break down and load rock ores onto trucks. Excavator bucket teeth are particularly important in coal mining as they facilitate the efficient extraction of coal. To optimize mining operations, it's important to use durable teeth which can withstand harsh mining conditions such as extreme temperatures and rocky landscapes. The main goal of this study is to select the appropriate teeth for mining at Khuut Coal Mining in Dundgobi with the aim of extending teeth’s lifespan. Previous teeth used in Khuut mining tend to last approximately 20 days and highlight the need for more durable teeth. The study employs field observations, laboratory testing, and data analysis to evaluate the performance of the bucket teeth and identify the factors that contribute to their longevity. The findings of this study aim to provide valuable insights into the design and selection of excavator bucket teeth for coal mining operations which can potentially benefit other mining industries as well.

Geotechnical and geomechanical aspects of pillar optimization on weak soil using Numerical Methods
(German Mongolian Institute for Resouce and Technology, 2023-05-18) Erdenetuya Gantulga; Thomas Hollenberg; Lothar te Kamp
Room and pillar mining is an established method used worldwide to extract coal, salt, and other minerals. Which method widespread use can be attributed to its relatively low cost, safety, and versatility in various geological conditions. The geotechnical and geomechanically aspects of optimizing pillars on unstable soil present mining engineers with significant challenges. It is essential to optimize pillars for the stability of underground mining operations. However, it is difficult to accurately foresee the behavior of weak soil and the surrounding rock mass due to its unique properties. Numerical methods can resolve these challenges by simulating the soil and rock mass behavior and assessing the pillars' stability.
