Dr.-Ing Hans Imgrund

Dr.-Ing. Hans Imgrund was born in Wesel Ginderich on May 25, 1938. After graduating from high school in 1958, he completed a preliminary internship at the blast furnace and steel mill of HOAG-Hüttenwerk Oberhausen AG. From the winter semester 1958/59 he studied ferrous metallurgy for two semesters at the Technical University of Berlin and then transferred to the Clausthal Mining Academy, where he also joined AV Glückauf-Salia.

In November 1963 he graduated as Dipl.-Ing. with the overall grade “very good”. In June 1966, as an assistant to Professor Wever at the TU Berlin, Institute for Metal Physics, he was awarded a doctorate in engineering.

His professional career began from 1969 to 1972 in Düsseldorf at Stahl- und Röhrenwerk Reisholz GmbH, in the testing department headed by Dr.-Ing. Clemens Florin, also a member of the AV Glückauf-Salia, head of the departments of high-temperature steels and metallography. Here he had his first professional encounter with molybdenum as a steel refiner. In 1973 he joined Climax Molybdenum GmbH in Düsseldorf, a subsidiary of Amax Inc. as Development Engineer. At that time Amax was a diversified mining group, active in molybdenum, nickel, iron ore, oil and gas. From 1976, as Sales Manager, he was responsible for marketing and sales of molybdenum and nickel – Germany and Eastern Europe. In 1978 he was appointed Managing Director of Climax Molybdenum GmbH and acted as Director of Sales for Central and Eastern Europe and Scandinavia. In 1980, Hans Imgrund also graduated from the Program of Management Development PMD39 at Harvard Business School in Boston, Massachusetts, as the basis for a successful career in international management. In 1981, he was promoted to Vice President Marketing and Sales Europe of Climax Molybdenum S.A. and moved with his family to Paris, which was associated with the start of school for his children Jan and Philipp at Lycee International. The second oil crisis in 1981 led to dramatic economic crises worldwide. Demand for molybdenum fell by 40% between 1979 and 1983. In 1985 followed the appointment as Senior Vice-President of Amax Europe S.A.,responsible for Marketing&Sales of Molybdenum, Nickel, Iron Ore with sales offices in Düsseldorf, London, Genoa and Stockholm. In June 1986 Hans Imgrund changed to Cyprus Minerals Company, Denver, Colorado as Sales Director of Molybdenum for Europe, Asia and Africa. Cyprus Minerals was the second largest copper producer in the USA at the time, producing significant quantities of molybdenum as a by-product. In October 1986, the new German company Cyprus Metals GmbH was launched, replacing Climax as market leader based on molybdenum products sold in Europe as early as 1988. Hans Imgrund’s philosophy was that customer satisfaction comes before profit maximization and the joint development of Mo-containing materials. In 1989 he acted as co-founder of IMOA – International Molybdenum Association (www.IMOA.info) and served as IMOA President in rotation from 1992 to 1994. In 1993 Cyprus and Amax merged to form Cyprus Amax Minerals Company, whereupon the Düsseldorf offices were merged to form Cyprus Climax GmbH and the radius of action was extended to include Japan. A reorganization of the sales offices in Europe and Japan with locations in Düsseldorf and London took place in 1993.

In 2003 Hans Imgrund retired and continued to act as a consultant and networker within IMOA and at international customer conferences in Düsseldorf. Hans Imgrund is married, has two sons and lives in Meerbusch.

Dr.-Ing. Bernhard Kleinsorge

Dr.-Ing. Bernhard Kleinsorge was born on September 28, 1966 in Meschede, Sauerland. After graduating from high school in 1986, he completed an internship as a mining technician for almost a year as a prerequisite for studying mining. Thereby he got to know first practice in different mining operations like lead/zinc and hard coal underground, preparation technology for hard coal and pyrite as well as limestone mining in different quarries and lime burning.

After this experience, he came to the TU Clausthal in the summer semester of 1987 and studied mining. He earned his undergraduate degree after four semesters, then took a semester off, and after another five semesters was able to complete his major in 1992. Of lasting memory during the vacation semester was a very extended trip to the United States with a Bundesbruder, another lengthy internship in the lime industry, and the reunification of the two German states that took place during that time.

After completing his studies, the opportunity arose to take on the role of personal assistant to the rector at the Clausthal University of Technology and, in parallel, to complete his doctorate at the then Mining Institute and the Institute for Processing in cooperation with a leading company in the lime industry.

After completing his doctorate, Bernhard Kleinsorge was able to start his first professional challenge in 1995 as an operating engineer for underground limestone mining in a subsidiary of this lime company. This led him to his first management positions until the year 2000, when he was appointed technical managing director. Due to various restructuring measures, he subsequently sought a new challenge at Lafarge SA, a French company in the cement industry. After working as a project engineer first at the German headquarters and then at the technical center in Vienna, he became plant manager of a cement plant near Karlsruhe in 2002. There, after a few years, the nice task arose for an engineer to be allowed to build a new kiln line. He then moved with the family to the technical center for Western Europe in France in 2008. After interesting years in Lyon and responsibility for the technical development of Lafarge’s cement plants in Spain, Italy and Greece, he took on the role of plant manager at what was once the GDR’s largest cement plant in Saxony-Anhalt in 2010. The greatest challenge here was the further development of the organization and personnel in order to master the ongoing technical challenges. In 2015, the opportunity arose to help organize the conversion of two rotary kilns at the two largest cement plants in Germany at Heidelberg Zement, in order to be able to take on the role of Technical Director for the Cement Division in Germany with 8 cement plants and 3 grinding plants in 2016.

In addition to his professional duties, Bernhard Kleinsorge has for many years been involved on a voluntary basis in various committees of employers’ associations, the cement industry association and in the employers’ liability insurance association, which has led in particular to experience in social partnerships.

Bernhard is married and has two adult children in education. He has been a member of the Rotarians since 2014, has been involved in local politics at his home in Baden-Württemberg for many years, and in the Catholic Church as a foundation councilor, lector, communion helper and the parish team.
