Kivimaa mine

Kivimaa mine is a science 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 Kivimaa mine rather than just read about it. In short: Kivimaa mine (Finnish: Kivimaan kaivos) was gold and copper mine active during the years 1969–1970 in Tervola at Sivakkajoki. During this time 18 587 tonnes of ore were extracted which contained 2.0 grams of gold per tonne.

Key takeaways

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

Reference excerpt

Kivimaa mine (Finnish: Kivimaan kaivos) was gold and copper mine active during the years 1969–1970 in Tervola at Sivakkajoki. During this time 18 587 tonnes of ore were extracted which contained 2.0 grams of gold per tonne. The concentration of copper in the ore was 1.20%. Outokumpu Ltd., which owned the mine, mined the quartz-carbonate veins with highest concentration of gold and copper. The ore from the mine was transported to the mine of Vihanti to be enriched. The mining ended on 12 December 1969. The buildings at the mine were taken down in the summer of 1974.

Worked examples

Example 1 — a first encounter with Kivimaa mine

Start with the simplest possible case. Write down what Kivimaa mine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Kivimaa 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 Kivimaa 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 Kivimaa mine

In research: Kivimaa mine appears in science 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 Kivimaa 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: Kivimaa mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Copper mines in Finland, Gold mines in Finland, Lapland (Finland) geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Kivimaa 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.
