Ministro Hales mine

Ministro Hales 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 Ministro Hales mine rather than just read about it. In short: Ministro Hales, formerly known as Mansa Mina, is an open-pit copper mine in the Atacama Desert of northern Chile. It lies at an altitude of 2,600 meters above sea level in an area of cold desert climate in the inland commune of Calama.

Key takeaways

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

Reference excerpt

Ministro Hales, formerly known as Mansa Mina, is an open-pit copper mine in the Atacama Desert of northern Chile. It lies at an altitude of 2,600 meters above sea level in an area of cold desert climate in the inland commune of Calama. The mine is located halfway between the city of Calama and the mine of Chuquicamata. Codelco owns and operates the mine. Ground work in the mine begun in 2011 with a large-scale pre-stripping operation. In 2024 Codelco planned to extend the mine life for several decades with the closure phase beginning in 2055 and ending in 2061. In January 2021 the eastern wall –that is the footwall– of the pit begun to be tracked for its stability and in early November 2021 its creep accelerated culminating in a collapse and slandslide on November 9, 2021. There were no deaths, injuries or major equipment losses. In 2024 it produced 122,200 tons of copper down from 126,000 tons in 2023 and 152,200 tons in 2022. As of 2024 Ministro Hales was the 14th most productive copper mine in Chile. It is named after Alejandro Hales (1923–2001) who served as the Minister of Mining from September 1992 to March 1994.

Worked examples

Example 1 — a first encounter with Ministro Hales mine

Start with the simplest possible case. Write down what Ministro Hales 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 Ministro Hales 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 Ministro Hales 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 Ministro Hales mine

In research: Ministro Hales 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 Ministro Hales 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: Ministro Hales mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chile geography stubs, Codelco, Copper mines in Chile, so understanding it makes those chapters shorter.
In everyday life: Look for Ministro Hales 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.
