SUMMER-WORKSHOP
June and July 2017, 14-days We/Sa, 15–17pm

Prospect for, analyse and refine raw materials yourself

Freiberg’s terra mineralia exhibition is offering a new series of summer workshops for anyone interested in prospecting for and analysing raw materials and enriching metals; the series is being conducted in cooperation with the Helmholtz Institute Freiberg for Resource Technology (HIF), part of the Helmholtz-Zentrum Dresden-Rossendorf, and other partners. All raw materials enthusiasts aged 12 and over are welcome to take part. The first workshop takes place on Wednesday 28th June 2017.

Scientists from Beak Consultants GmbH and the HIF and TU Bergakademie Freiberg invite you to join them over the coming weeks on the search for Saxon raw materials. In the summer workshops, we’ll also be looking at the processes and technologies required to actually extract metals from crude ore. Attendees will get hands on with the research. At each workshop, they’ll learn about a different project from the ongoing ‘r4 – Innovative Technologies for Resource Efficiency – Research for the Supply of Raw Materials of Strategic Economic Importance’ research initiative funded by the Federal Ministry of Education and Research. As a result, they’ll understand how challenging it is to extract the metallic raw materials we take for granted in our everyday lives – whether they’re used for coins, batteries or cars.

First Workshop: Minerals in High-Tech Analysis
28. June and 1. July 2017 at 3pm

Ort: terra mineralia, Freudenstein Castle, Schloßplatz 4, 09599 Freiberg

Lots of people are familiar with optical microscopes. But scientific research also uses far larger and more complex instruments to study raw materials. In this first workshop, attendees will learn how to prepare ores for them, and what information modern analytics provides. They’ll take part in a quiz on the Pöhla deposits in the Ore Mountains as well as visiting a research laboratory. Because if you don’t know the precise properties of minerals, you can’t improve their mining and processing.

Second Workshop: Prospecting for Ores in the Ore Mountains
12. July and 15. July 2017 at 9am

Meeting Point: Fuchsmühle, 09633 Halsbrücke.
GPS Coordinates:

50°56’15.20“ N
13°22’28.66“ O


Venue of the Workshop: At the Mulde River close to Freiberg between Tuttendorf, Conradsdorf and Halsbach.

The second workshop takes place in the open country. Attendees will have the opportunity to work like geologists and go prospecting for raw materials themselves. They’ll find out what streams tell us about ore deposits and they’ll learn the essentials of what’s called ‘stream sediment sampling’. They’ll be able to test their own skill and geological knowledge as they try out prospecting – sifting valuable materials out of stream sediments. To find out where they should go prospecting, attendees will identify catchment areas with the help of a topographical map themselves. The workshop will also look at subsequent analysis of the samples.

Third Workshop: The Virtual World of the Geologist
26. July and 29. July 2017 at 3pm

TU Bergakademie Freiberg, Institute of Computer Science, Humboldt-Bau, Bernhard-von-Cotta-Straße 2, 09599 Freiberg

The third workshop is aimed at anyone who wants to know how raw material accumulations are formed and how this knowledge helps with the discovery of new deposits. Three-dimensional geological models are an important tool here. In X-Site Cave, TU Bergakademie Freiberg’s Institute for Computer Science possesses a space into which these kinds of models and other complex environments can be projected. Attendees will visit this space and have the opportunity to experience the Ore Mountains and their tin deposits there virtually.

Fourth Workshop: The Cinderella Principle – How Flotation Works
2. August and 5. August 2017 at 3pm

Ort: terra mineralia, Freudenstein Castle, Schloßplatz 4, 09599 Freiberg

The goal of processing is to separate ore minerals from unusable gangue minerals. To do this, the flotation process is often used. Its essentials and principle of operation will be explained using  demonstrations. Attendees can also experiment themselves. They’ll do soap boat racing, for example, to learn the significance of surface properties for flotation and how they can be influenced. The fourth workshop also incorporates the SMoOMaP computer game on how scientists separate minerals from one another.

Registration and Participants

Each of the four topical workshops lasts 2 hours and takes place twice, once on a Wednesday and once on a Saturday. Start time is 3pm. The ‘Prospecting for Ores in the Ore Mountains’ workshop takes place in the open country and thus starts at 9am. All of the events are free of charge. To register, please contact the terra mineralia Info Desk (03731 394654 or fuehrungen@terra-mineralia.de).

The workshops are aimed at anyone over 12 years of age. Space is limited to 15 individuals. A minimum of 5 attendees must be registered for any one workshop to take place. Registration closes on Tuesdays for Wednesday workshops, and on Thursdays for Saturday workshops. Information on where to meet will be provided to attendees following registration.
