MIM Holdings 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 MIM Holdings rather than just read about it. In short: MIM Holdings Limited was an Australian mining company founded in 1970 as the parent company of Mount Isa Mines, which operates the Mount Isa mines in north-west Queensland. Based in Ann Street, Brisbane, MIM Holdings owned and/or operated coal, gold, and base metal mines in Australia and Argentina.

Key takeaways

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

Reference excerpt

MIM Holdings Limited was an Australian mining company founded in 1970 as the parent company of Mount Isa Mines, which operates the Mount Isa mines in north-west Queensland. Based in Ann Street, Brisbane, MIM Holdings owned and/or operated coal, gold, and base metal mines in Australia and Argentina. It also operated lead and copper smelters in Mount Isa, a copper refinery in Townsville (Queensland), a lead refinery at Northfleet (England), zinc smelters using the Imperial Smelting Process at the National Smelting Company located within Avonmouth Docks (England) and Duisburg (Germany), and a precious metals refinery in Sydney. In the early 1980s, it was briefly Australia's largest company by market capitalisation. It also held, at some stages, cross-shareholdings in ASARCO, Cominco and Metallgesellschaft. It sold its interests in Cominco and Metallgesellschaft during the 1993–1994 Australian financial year. MIM Holdings was responsible for several significant technological advances in the mining industry, including the Isa Process tank house technology, developed at its subsidiary Copper Refineries Pty Ltd in Townsville; the Bottom-blown oxygen converter developed at its lead refining subsidiary, Britannia Refined Metals, at Northfleet in England; and the ISASMELT top-entry submerged lance smelting process, Jameson Cell flotation technology, and the IsaMill fine grinding technology, all developed at its Mount Isa Mines Limited operations in Mount Isa. MIM Holdings was taken over by Xstrata for a total of US$2.96 billion in 2003 and delisted from the Australian Securities Exchange on 30 June 2003. At that time, MIM Holdings was one of the world's biggest coal exporters.

Worked examples

Example 1 — a first encounter with MIM Holdings

Start with the simplest possible case. Write down what MIM Holdings 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 MIM Holdings 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 MIM Holdings 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 MIM Holdings

In research: MIM Holdings 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 MIM Holdings 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: MIM Holdings is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970 establishments in Australia, 2003 disestablishments in Australia, Coal companies of Australia, so understanding it makes those chapters shorter.
In everyday life: Look for MIM Holdings 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.
