Lavender Pit

Lavender Pit 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 Lavender Pit rather than just read about it. In short: The Lavender Pit is a former open pit copper mine near Bisbee in Cochise County, Arizona, United States. It is located near the famous Copper Queen Mine.

Key takeaways

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

Reference excerpt

The Lavender Pit is a former open pit copper mine near Bisbee in Cochise County, Arizona, United States. It is located near the famous Copper Queen Mine. The Lavender Pit was named in honor of Harrison M. Lavender (1890–1952), who as vice-president and General Manager of Phelps Dodge Corporation, conceived and carried out this plan for making the previously unprofitable low-grade copper bearing rock of the area into commercial copper ore. Phelps Dodge Corporation opened the Lavender Pit in 1950, at the site of the earlier, higher-grade Sacramento Hill mine. Production through 1974 totaled 86 million tons of ore averaging about 0.7% copper, or about 600,000 tons of copper produced, with gold and silver as byproducts. About 256 million tons of waste were stripped, but a portion of this was acid-leached for additional copper. Turquoise was also a by-product of this mining activity. Bisbee turquoise, also known as Bisbee Blue, is amongst the finest turquoise found anywhere in the world. Mining operations in the pit ended in 1974. The undeveloped Cochise deposit, located immediately north of the Lavender pit, contains an estimated 190 million tons of rock containing 0.4% acid-soluble copper, which may be mined in the future. Because of the competent host rock, this pit has much steeper sides than other open pit copper mines in the southwest area. The pit covers an area of 300 acres (1.2 km2), and is 900 feet (274 m) deep. Large tonnages of dump rock are placed around Bisbee, notably north of the residential district of Warren and other parts of the southeastern Mule Mountains area.

Geography The mine is at 31°25′55″N 109°53′57″W, at an altitude of 4941 feet (1506 m) above mean sea level.

Worked examples

Example 1 — a first encounter with Lavender Pit

Start with the simplest possible case. Write down what Lavender Pit 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 Lavender Pit 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 Lavender Pit 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 Lavender Pit

In research: Lavender Pit 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 Lavender Pit 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: Lavender Pit is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 establishments in Arizona, Bisbee, Arizona, Copper mines in Arizona, so understanding it makes those chapters shorter.
In everyday life: Look for Lavender Pit 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.
