Penrhyn Dû Mines
The Penrhyn Dû Mines are a collection of mines situated near Llanengan on the Llŷn Peninsula. It encompasses the Penrhyn, Assheton, Western and Tan-y-Bwlch mines. The whole region can be called Penrhyn Du which literally means "black headland". Tan-y-Bwlch Mine was probably the richest of the mines with a recorded output of of lead ore, of zinc ore and of copper ore between 1873 and 1886. History There is a possibility that Roman miners were the first to mine the Penrhyn Dû headland After any Roman mining the mines were rarely worked until the reign of Elizabeth I where the need for lead was high. In 1637 Thomas Bushel was asked by Charles I to inspect and report on the prospects for Welsh mining. In his report of that year Bushel states: "...that at Pottherly there is a vein which has never been wrought though known about these twenty years..." during the 18th century various pumping engine powered by water wheels and horses were installed and in the early par ...

Abersoch
Abersoch is a village in the community of Llanengan in Gwynedd, Wales. It is a popular coastal seaside resort, with around 800 residents, on the east-facing south coast of the Llŷn Peninsula at the southern terminus of the A499. It is about south-west of Pwllheli and south-west of the county town of Caernarfon. The village takes its name from the river Soch, which reaches the sea in the village. 'Aber' meaning 'estuary', gives us a literal translation of the 'Soch Estuary'. Archaeology In the dry summer of 2018, aerial photography at Fach Farm, some 1100 metres north of the bridge over the Afon Soch, identified crop marks that were reported as a possible Roman fortlet. High-resolution geophysics in 2019 revealed evidence of a complex defended enclosure, unlike Roman military structures but suggesting a pre-Roman date. Tourism Built upon the fishing trade, Abersoch was once a small village which grew exponentially after the 1950's with the rise of tourism. The fishing port ...

Manganese Mines In The United Kingdom
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
