Ore leach­ing (in ger­man)The metal extraction by ore leaching (mostly copper) was about 1,000 years BC. known in the Mediterranean, but there are also barely no written records. The in the Middle Ages and in the following Renaissance well-known different procedures were first described in detail by Georg Agricola 1556 in his book "De Re Metallica Libri XII".

Min­er­al Days in Mu­nich 2012 or „The Mu­nich Show“For the 49th year once again the Munich Mineral Show was held. A few years ago under the old leadership the motto almost entirely stood under the theme of minerals and fossils. This year not only the name seems to change away from the "Munich Mineral Show" changing to "The Munich Show". The new exhibition management, led by the young Mr. Keilmann seems not quite knowing where to go or has something bigger in mind. One can imagine something in "Munich Mineral Days", it is difficult in the name "The Munich Show". The new show management seems to leave the common way, to keep all options open with a new name. - A comment and fair report written in german language by Stefan Schorn

Bro­ken Hill in Aus­tralienErste Expeditionen in die Barrier Ranges gab es 1844-46. Silbererz wurde auf dem Grundstück der Thackaringa Schafzucht gefunden. Patrick Green gründete die erste Mine "The Pioneer" 1876. 1883 fand Charles Rasp schwarzes Gestein und vermutete Kassiterit; also schickte er Proben zur Analyse. Darin waren Silber und Blei, aber nicht genug, um wirtschaftlich zu werden. Die Proben, manganhaltiges Eisenerz, stammten aus der Oxidationszone. Im Laufe des Jahres wurden mehr Proben entnommen, die Broken Hill zu einer großen Entdeckung machten.

FroschEin Geleucht des Bergmanns. Frosch werden diese Geleuchte in Anlehnung an ihr Aussehen genannt. Jede Zeit und jedes Bergbaugebiet hatte unterschiedliche Frösche. Es gab den erzgebirgischen Frosch, den westfälischen, den Siegerländer usw.. Die Montage mittels Hartlot geschah in einem Schmiedefeuer. Als Flussmittel diente Stroh. Die Besonderheit hierbei ist das Lot, auch Rotschlag oder Gelbschlag genannt. Das körnige Lot wurde mittels einer Tülle den Baugruppen zugegeben. Dieses Lot dient heute dem Fachmann als Beweis der Originalität eines Frosches.

The Mu­nich Show 2024The mineral fair ended successfully and the author of this article received only positive feedback. Many dealers were extremely satisfied. According to the organizer, 18,000 guests visited the halls on Saturday alone. Both days were a hive of activity and the numerous children's attractions were well received. Parents were everywhere with their children to complete the geo-rally.

For mineral collectors, the usual dealers were on site, although some tables remained empty. There were no highlights from the scene or overflowing tables with identical material from new finds. However, one stand with an impressive selection of Germanite chunks was a welcome novelty.

The special exhibition “The Impossible Crystal” was a success. Even if not all the exhibits could be described as “impossible crystal”, all the pieces were of the best quality and well worth seeing. In the B halls, the author visited the “Young Designers”, including a student who presented cast silver jewelry in an organic design that showed off the embedded stones to their best advantage - an impressive piece of work...

The Franken­holz Mine – A Hid­den Chapter of In­dus­trial His­to­ryFrom early tunnel construction in the 18th century to its final closure in the 1950s, the Frankenholz Mine in Germany’s Saar region was a key site of coal mining history. With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era.

Ge­ol­o­gisch­es Por­trait - Schie­ferDer Begriff "Schiefer" ist ein Polysem, welcher seit grauer Vorzeit (althochdeutsch scivaro (Holz-, Steinsplitter); mittelhochdeutsch schiver(e) (Stein-, Holzsplitter); mittelniederdeutsch schiver (Schiefer, Schindel) bis heute nicht scharf definiert und differenziert wurde. Allgemein und bergmännisch werden als Schiefer deutlich parallel angeordnete, in dünnen, ebenen Platten spaltbare Gesteine bezeichnet. Unter diesen Sammelbegriff fallen jedoch auch Tonschiefer, Schieferton, Tonstein, kristalline Schiefer, echte und unechte, kristalline und metamorphe Schiefer und viele, viele synonyme Schiefer-Wortgebilde und lokale Bezeichnungen- was nicht zu einer eindeutigen Definition beiträgt.

Nicht anders war (und ist) die Verwirrung in England, wo die Begriffe slate, shale und shist nicht deutlich getrennt wurden; im untertage Kohlebergbau hieß shale auch häufig slate. In Spanien heißt der für Dächer und Tafeln verwendete Schiefer pizarra, petrologisch aber equisto bzw. arcilla equistosa; im französischen heißen wissenschaftlich alle Schiefer schiste, aber der im Steinbruch gebrochene Schiefer ist ....
