Lakeview Mining Company

Lakeview Mining Company 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 Lakeview Mining Company rather than just read about it. In short: The Lakeview Mining Company was a uranium reduction plant 1.5 miles (2.4 km) north of Lakeview, Lake County, Oregon. The mill began operating in February 1958 and operating until November 1960.

Key takeaways

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

Reference excerpt

The Lakeview Mining Company was a uranium reduction plant 1.5 miles (2.4 km) north of Lakeview, Lake County, Oregon. The mill began operating in February 1958 and operating until November 1960. The site covered 258 acres (104 ha); 130,000 short tons (120,000 t) of ore were processed, leaving behind large amounts of residual radioactive material. These were moved to an engineered disposal cell in 1986–1988.

The plant was built in 1957–1958 for a cost of approximately $3 million, selling the yellowcake to Atomic Energy Commission. The plant employed approximately 50 workers. Two successful mines were open in the area, Lucky Lass and White King, feeding the Lakeview plant. Seven raffinate ponds across 69 acres (28 ha) were used for the uranium extraction process, and a 30 acres (12 ha) uranium tailings pile existed. In 1961 Kerr-McGee purchased the site; it changed hands several times and by 1968 was owned by Atlantic Richfield (ARCO), which began radiation remediation. More radiation was found in 1976, leading to an ARCO decontamination in 1977 and then sale in 1978, when a lumber company purchased the mill site and reused the ponds and buildings on the eastern edge as a lumber mill. The Uranium Mill Tailings Radiation Control Act was passed in 1978, leading to federal control of remediation. Starting in 1986, the US Department of Energy remediated the site, creating an engineered disposal cell approximately 6 miles (9.7 km) away. 926,000 cubic yards (708,000 m3) (726,000 short tons (659,000 t)) were removed from the mill site, creating a 16 acres (6.5 ha) cell. Work was completed in June 1988 at a cost of $24.5 million. The majority of the contamination was from the ponds, not the tailings pile. The National Renewable Energy Laboratory and EPA visited the site in 2012 for a feasibility study on geothermal heating, as it is adjacent to Hunter's Hot Springs. The report found it to be "economically marginal". The lumber mill is still in operation, having been purchased by Pacific Pine Products in 1995, producing custom doors with imported lumber for their Lakeview Millworks division. The company is still using some of the original buildings. A solar power farm was planned on the western 170 acres of the former mine by Origis Energy in 2016. It was completed in 2017 and named OR Solar 6.

Worked examples

Example 1 — a first encounter with Lakeview Mining Company

Start with the simplest possible case. Write down what Lakeview Mining Company 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 Lakeview Mining Company 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 Lakeview Mining Company 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 Lakeview Mining Company

In research: Lakeview Mining Company 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 Lakeview Mining Company 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: Lakeview Mining Company is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cleaning and the environment, Lake County, Oregon, Radioactive waste, so understanding it makes those chapters shorter.
In everyday life: Look for Lakeview Mining Company 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.
