Løkken Mine

Løkken Mine is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Løkken Mine rather than just read about it. In short: The Løkken Mine is an underground pyrite mine located in the present-day Orkland Municipality in Trøndelag, Norway. The mine was operative from 1654 to 1987, located in the mining community Løkken Verk.

Key takeaways

Løkken Mine belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Løkken Mine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Løkken Mine from memory before moving on to harder problems.

Reference excerpt

The Løkken Mine is an underground pyrite mine located in the present-day Orkland Municipality in Trøndelag, Norway. The mine was operative from 1654 to 1987, located in the mining community Løkken Verk. It contained the largest deposits of its kind in Norway.

History From 1654-1904, the mine used traditional mining methods, focusing on the mining of copper only. Between 1654 and 1845, a total of 11,300 tonnes (11,100 long tons; 12,500 short tons) of copper was produced from the mine. From 1904-1987, the mine switched to modern, large-scale production of ore. The mine was taken over by the company Orkla Grube-Aktiebolag. Electricity was added to the mine. From 1904 until 1987 a total of 24,000,000 tonnes (24,000,000 long tons; 26,000,000 short tons) of pyrite was produced from the mine. In addition to sulfur, the pyrite contained about 2% copper, in addition to zinc, and traces of silver and gold. The products were originally transported to the sea by horse and sledge during winter time. From 1908, the ore was transported by the Thamshavn Line, which was the first electrical railway line in Norway. A smelting plant was located in Thamshavn. The annual production of the mine was about 350,000 tonnes (340,000 long tons; 390,000 short tons) of ore during its final years. Since its closure in 1987, the mine is owned by the Orkla Group and it is now a museum.

Worked examples

Example 1 — a first encounter with Løkken Mine

Start with the simplest possible case. Write down what Løkken Mine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Løkken Mine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Løkken Mine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Løkken Mine

In research: Løkken Mine appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Løkken Mine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Løkken Mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1654 establishments in Norway, 1987 disestablishments in Norway, Buildings and structures in Trøndelag, so understanding it makes those chapters shorter.
In everyday life: Look for Løkken Mine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
