Thrilling mysteries to solve for all the family at terra mineralia

In the holidays from 24 June to 6 August 2017, families have the chance to investigate a crime together at terra mineralia. Our special exhibition ‘CSI Freiberg. Murder at terra mineralia’ is aimed at visitors young and old. The body of renowned scientist Kathrin Berg has been discovered amongst the beautiful minerals. She’s an expert in rare earth elements. But who’s behind this misdeed? Visitors will carry out their investigations like a real detective, learning as they search for the murderer about the rare earths that we need for all sorts of things in our everyday lives.

Children from 7 years upwards will carry out their investigations along with Gustav Gecko. Gustav is a little lizard who lives with renowned scientist Kathrin Berg. In his terrarium he has a cosy hiding stone, his favourite place in the world! One day, the professor takes the stone to a very important meeting at terra mineralia. But neither returns… Gustav Gecko decides to set out in search of them. Along the way, he discovers that his stone is special because it has rare earths in it. Now he’ll have to proceed like a real detective. This way, he’ll help the police with their enquiries so he can clear up the mystery of the hiding stone and even solve the crime.

In the Voyage of Discovery, the exhibition’s science centre, boys and girls can also train as a detective. They’ll learn how to take and read fingerprints, how to search for clues and how to crack secret codes. The detective training also covers analysing specimens of hair, threads, and samples of marks and stains. With this knowledge, any child can be a brilliant help to Gustav Gecko as he searches for his hiding stone!

The ‘Gustav Gecko is looking for his stone’ holiday programme and detective training will take place between 10am and 5pm, Thursdays to Sundays from 24 June to 6 August 2017. Nursery and kids club groups are requested to register in advance. For more information, please get in touch with the terra mineralia Info Desk on 03731 394654 or by email to

adults €12/person,
pre-school and school-age children and students €6/child,

From drones to flotation cells – on the hunt for Saxon raw materials

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 2017 and 1 July 2017 at 3pm

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 2017 and 15 July 2017 at 9am

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 2017 and 29 July 2017 at 3pm

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 2017 and 5 August 2017 at 3pm

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

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.

30 September – 15 October 2017, 10am–5pm

Minerals and mankind

Hard to believe, but it’s true: there are minerals inside of us! Set out on an exciting quest and find out what the minerals in our body do. You’ll also get to know minerals that enable robots to walk and mobiles to make calls. There are loads of experiments waiting for you in the Voyage of Discovery. You’ll be able to test what our bones, blood and skin would look like without minerals.

22 November – 23 December 2017, Weds 5pm and Sat 6pm

Family tour: Night-time in the museum

Get ready for a really special trip to the museum. Explore terra mineralia in the dark, armed with head torches and UV flashlights! Fluorescent minerals in the display cabinets will glow in every colour imaginable for you and your family.
