Eberhard Gock

from Wikipedia, the free encyclopedia

Eberhard Gock (born February 22, 1937 in Staßfurt ; † September 28, 2016 in Goslar ) was a German engineering scientist and until his retirement in 2007 was a professor at the Institute for Processing, Landfill Technology and Geomechanics (IFAD) of the Clausthal University of Technology, as well as author and co-author numerous publications in his field.


The engineer's son, Otto Gock, attended elementary and high school in Staßfurt from 1943 to 1955 . 1956 Abitur at the Sophie-Scholl-Oberschule in Berlin-Schöneberg. After an internship in extraction and refining companies in the potash, ore and coal mining as well as the oil industry, Gock studied geology and then mining at the TU Berlin from 1958 to 1966 ; In his diploma thesis, completed in 1966 in the field of processing and processing technology, he dealt with the flotation of a lead-zinc ore from Bad Grund and the design of a processing plant. Two years later he was awarded a Dr.-Ing. Degree from the TU Berlin with his dissertation "Contribution to the mechanical activation of titanium magnesite" PhD. In 1974 he married the Slavist Anna Gock, b. Hank. Since his dissertation, research into vibratory grinding in the processing of mineral raw materials and residues from the perspective of mechanochemistry has played a central role in Gock's scientific work: his habilitation thesis "Influencing the dissolving behavior", which he presented to the Department of Mining and Geosciences at the TU Berlin in 1977, proved to be a decisive step sulphidic raw materials through solid-state reactions during vibratory grinding ”. which also triggered research into the mechanics of vibratory tube mills and their more efficient design. In 1983 Gock built a bridge between chemical engineering, process engineering, technical mechanics as well as the mining and geosciences by founding the “Raw Materials Technology” department at the TU Berlin. In 1986 Gock received a temporary research professorship from the TU Berlin with a scientific focus on "chemical processing" and until his appointment to the TU Clausthal (successor Albert Bahr) he headed an interdisciplinary research team consisting of chemists, geologists, mineralogists, mechanics , Process and mining engineers.

In Clausthal, Gock, who ran the Institute for Processing and Refinement with Klaus Schönert , played a key role in the strategic reorientation towards the Institute for Processing and Landfill Technology, which plays a key role in teaching and research in the raw materials and geotechnical engineering course of the Mining and Raw Materials Department : In September 2017, the Institute for Processing, Landfill Technology and Geomechanics (IFAD), which consists of three chairs, celebrated its 90th anniversary. Gock was followed by Daniel Goldmann in January 2008 (today: Chair of Raw Material Processing and Recycling).

With great success, which was also recognized internationally, Gock integrated the chemical processing of raw and residual materials into the disciplinary framework of environmental process engineering. This is expressed not only in more than 30 dissertations supervised by him, but in over 30 patents, mostly in the field of hydrometallurgy ; Since the late 1970s, increasing the efficiency of vibratory tube mills played a decisive role, both scientifically and technically: An example of this is the dissertation supervised by Gock “On the internal kinematics and kinetics of vibratory tube mills” by Karl-Eugen Kurrer and the development of the Rotary chamber vibratory mill named. which in 1988/89 led to the single-tube vibratory mill with chamber wheel and in 1993/94 finally to the eccentric vibratory mill patented in 1996. With the centrifugal tube mill, another machine for fine comminution was developed at the Gock chair.

Under his leadership, numerous research and development work was carried out in the field of processing and recycling of waste from raw material extraction: sludge ponds from barite mining , dumps from non-ferrous metal ore mining , electronic scrap recycling (filter dust), the beverage industry (filter sludge ), chemical process engineering (phosphating solutions from the Corrosion protection, H 2 SO 4 from TiO 2 pigment production) and steel metallurgy (dezincification of steel scrap). All of the work testifies to the high level of processing and process engineering as a practice-oriented process science. Gock's scientific and technical oeuvre showed that, in addition to the mechanical processing processes that were the focus in the past, processing processes without chemical processes are no longer conceivable today due to the increasingly complex material systems.


  • For the invention and development of the eccentric vibratory mill, Gock was awarded the Technology Transfer Prize of the Braunschweig Chamber of Commerce and Industry in 1998.
  • Together with Otto Carlowitz, Gock accepted the German Raw Material Efficiency Prize 2012 for the Clausthal joint project “Dezinken von Stahlschippen”.
