DMUV German-Mongolian Business Association, Ulan Bator, MONGOLIA - Elaboration of a Market Study - Mining Industry in Mongolia

Mongolia is one of the ten most resource-rich countries in the world. In the south of the country, which is only very sparsely populated with a total of around 3.4 million inhabitants, there are gigantic deposits of copper, silver, gold, coal, fluorspar and other raw materials in the Gobi desert, which are among the largest in the world. Coal, copper and gold are the most important deposits and account for about 89% of Mongolia's export economy and over 20% of the country's gross domestic product. Accordingly, mining is now the most important industrial sector in the country from an economic point of view.

The market study provides an overview of the current status of mining activities in Mongolia ten years after the conclusion of the German-Mongolian Raw Materials Agreement, with a special focus on the implementation of the raw materials agreement's goals for German industry under the current conditions.

Skorpion Zinc Mines, NAMIBIA - Optimisation of Energy Consumption

In Namibia the mining industry is one of the major energy consumers. Since energy costs negatively influence the operating costs of the mines, in particular the processing plants, they invariably result in an overall increase of production costs. A substantial part of this energy is directly imported from South Africa, the cost of which has been increasing rapidly in the past years and will most likely continue on the same path in the years to come.

Consequently, the major target of the Namibian mines currently is to address possible energy savings challenges and to investigate possibilities for the mines to generate their own electricity during peak times. This is in alignment with the mines’ strategic plan and objective to minimise the total energy costs through the reduction of energy consumption from both the national and foreign power grids. We reported on some of the key energy consumption optimization challenges addressed through a case study carried out in cooperation with Skorpion Zinc Mines and Refinery. In particular, we investigated the recovery and re-use of waste process energy and the production of additional energy from solar to decrease the demand of electricity import.

RAG AG, Essen, GERMANY - World Heritage Site Zollverein - Modification of a Central Mine Drainage Station to Backup Site for Eternity

Currently on Zollverein main drainage station underground installed pumps are under operation. The underground pumping station is installed on 14th level which is approximately -950 m asl. The water quantity which had to be pumped on average during the last five years amounted to 12.4 m³/min. The mine water is pumped through two standpipes with 500 mm diameter installed in Zollverein 2 shaft to the surface and further to Emscher river which is used as open sewage duct. Thereby, the water containing sulphate coming from the southern area (approx. 7.5 m³/min) and the barium-containing water coming from the northern area (approx. 4.9 m³/min) are pumped separately.

The two shafts Zollverein 2 and Zollverein XII have to be modified into wells as dewatering backup sites by using cladding tubes in Zollverein 2 and a concrete advancing column in Zollverein XII when in 2020 the current dewatering discharge authorization into the Emscher expires. Both cladding and well tube should reach up to a depth of 650 m.

Activity performed: 

  • Project Management on World Heritage Site Zollverein - Modification of a Central Mine Drainage Station to Backup Site for Eternity (Planning and Construction)

Sustainable Mining NamDeb, NAMIBIA- Conventional Open Pit Mining versus Concurrent Open Pit Mining

Concurrent mining describes backfilling one zone while depleting subsequent zones for production purpose. This leads to the following challenges.

  • If the Bedrock cleaning process is delayed then backfilling will be halted
  • A shortage of haul trucks, means priority is to feed the process plant, this results in the concurrent cycle being interrupted,
  • When the process plant is unavailable you have to stockpile material, and the concurrent cycle is interrupted because there is no waste/ oversize to backfill depleted zones.

Objectives of the study are to

  • Investigate and demonstrate the feasibility, challenges as well as advantages of Sustainable Open Pit Concurrent Mining versus Conventional open pit mining
  • Establish the conditions under which concurrent Mining open pit mining may be implemented as opposed to Conventional Open Pit Mining and why Mining companies currently opt for the latter

Okorusu Fluorspar Mine E-Deposit, NAMIBIA - Feasibility Study

The Okorusu Fluorspar mine explored a new fluorite deposit starting 2009. An independent South African Company, Geotech Africa, was asked to develop an open pit mining concept after modelling the E-deposit based on the raw drillhole data in 2013. The design proposed was basic and required further investigation into the viability of the mining concept. Due to existing open pit operations, the company proposed a study on the viability of exploiting the deposit using underground mining methods and the existing surface mining equipment The primary objective of this study is to serve as a scoping study through investigation of underground mining method concepts in terms of technical and economic viability and feasibility, given the challenging nature of the E-Deposit as well as possible further use of surface mining equipment. It will serve as a first scope optimisation study to indicate the viability of mining underground with existing equipment.
