Luarica diamond mine

Luarica diamond 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 Luarica diamond mine rather than just read about it. In short: The Luarica diamond mine is a diamond mine located in Angola. The mine is owned by a consortium of diamond mining companies, the two largest holders being Endiama with a 38 percent ownership, and Trans Hex with a 32 percent ownership.

Key takeaways

Luarica diamond 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 Luarica diamond mine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Luarica diamond mine from memory before moving on to harder problems.

Reference excerpt

The Luarica diamond mine is a diamond mine located in Angola. The mine is owned by a consortium of diamond mining companies, the two largest holders being Endiama with a 38 percent ownership, and Trans Hex with a 32 percent ownership. In 2004, the Luarica mine produced about 95,000 carats (19 kg) of diamond from over 632,000 cubic meters of processed ore. Of this production 84,000 carats (16.8 kg) was sold in 2004 at an average price of over US$300 per carat (1500 $/g), marking a new high for Angolan diamond production. The mine's Probable reserves are 1.3 million cubic meters of ore, at an ore grade of 21.6 carats (4.32 g) per 100 cubic meters (43.2 mg/m3). There is a waste rock overburden of about 9.5 million cubic meters. Mining operations were suspended in May 2009 due to a decline in diamond demand caused by the Great Recession. Trans Hex announced in August 2011 that it planned to withdraw from its two Angola joint-ventures with Endiama—Luarica and Fucauma—after failing to reach an agreement with the Government of Angola (which owns the other major partner, Endiama). Endiama stated that it planned to restart operations alone.

Worked examples

Example 1 — a first encounter with Luarica diamond mine

Start with the simplest possible case. Write down what Luarica diamond 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 Luarica diamond 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 Luarica diamond 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 Luarica diamond mine

In research: Luarica diamond 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 Luarica diamond 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: Luarica diamond mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Angola geography stubs, Diamond mines in Angola, Mine stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Luarica diamond 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.
