Phelps Dodge

Phelps Dodge 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 Phelps Dodge rather than just read about it. In short: Phelps Dodge Corporation was an American mining company founded in 1834 as an import-export firm by Anson Greene Phelps and his two sons-in-law William Earle Dodge, Sr. and Daniel James. The latter two ran Phelps, James & Co., the part of the organization based in Liverpool, England.

Key takeaways

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

Reference excerpt

Phelps Dodge Corporation was an American mining company founded in 1834 as an import-export firm by Anson Greene Phelps and his two sons-in-law William Earle Dodge, Sr. and Daniel James. The latter two ran Phelps, James & Co., the part of the organization based in Liverpool, England. The import-export firm at first exported United States cotton from the Deep South to England and imported various metals to the US needed for industrialization. With the expansion of the Western frontier in North America, the corporation acquired mines and mining companies, including the Copper Queen Mine in Cochise County, Arizona and the Dawson, New Mexico coal mines. It operated its own mines and acquired railroads to carry its products. By the late 19th century, it was known as a mining company. On March 19, 2007, Freeport-McMoRan completed a $25.9 billion acquisition of Phelps Dodge Corporation.

History in 1821, Anson G. Phelps started a partnership in New York City with Elisha Peck, a merchant who had been in trade in Berlin, Connecticut. Peck moved to Liverpool to run the British end of their business, an import-export company that shipped US-grown cotton from the Deep South to England, importing tin, iron, copper and other metals essential for industrial growth and development in the United States. In 1834, Peck left the business and was replaced in Liverpool by Daniel James, who remained there until his death in 1876. It was at this time that the concern of Phelps Dodge and Company was begun. In 1940, the Phelps Dodge Corporation provided the copper used to bind a commemorative book on the making of the film Arizona. The text inside the back cover reads "Columbia Pictures gratefully acknowledges the cooperation of the Phelps Dodge Corporation in making available the copper in the covers of this book."

Expansion When Anson G. Phelps died, his sons-in-law purchased his portion of the company, but retained the name, and the import-export business. In 1880, the company invested in the Detroit Copper Company of Clifton, Arizona, at the time a very small copper camp in the eastern Arizona Territory. Phelps-Dodge interested Dr. James Douglas of Phoenixville, Pennsylvania to inspect the property and make recommendations. Dr. Douglas inspected the Detroit Copper Co of Morenci and also ventured south to the Warren District. On his advice, Phelps-Dodge began its own mining operations in the Warren District with the purchase of the Atlanta Copper Mine in 1882, neighboring the Copper Queen Mine. When both mines discovered the same ore body, instead of fighting over it, they merged in 1885, creating the Copper Queen Consolidated Mining Company. The Copper Queen Mine in Bisbee, Arizona Territory, became one of the most productive in the state of the early 20th century. The company focused largely on providing copper wire and cables to industry, products that were in high demand as the Industrial Revolution took hold. As the company diversified, it began investing in new railroads, essential in the company's efforts to keep costs as low as possible, especially in Arizona Territory. It used its own lines to transport products to and from major railroads for its markets on the eastern/northeastern shores. In 1895, the first contract was signed by Phelps Dodge and Company and the Nichols Copper Company (which was renamed from G. H. Nichols and Company in 1891) to have Phelps Dodge deliver a minimum of 1,000,000 pounds (450,000 kg) of blister copper over three years. This economically symbiotic relationship lasted until 1922, in which Phelps Dodge provided 90% of the blister copper Nichols Copper Company used to produce 100% pure copper. During the 1920s, Phelps Dodge invested $3.5 million in the Nichols Copper Company's plant modernization projects in exchange for stock in Nichols Copper Company. This dramatically increased copper production of the plant. In 1930, Dr. William Henry Nichols died; Phelps Dodge purchased the Laurel Hill plant that same year. During the late 19th century, in concert with its metal interests, Phelps Dodge Corporation became one of the largest producers of lumber and lumber products in the United States. In Tombstone, Arizona during 1900, E. B. Gage, Frank Murphy, and William Staunton consolidated their various mining properties into a single entity, the Tombstone Consolidated Mines Company. They worked to drain mines that had filled with water, laid a rail spur into town, and revived mining. They experienced some success until the pumps failed in 1909. The new company filed for bankruptcy and the Phelps-Dodge Corporation acquired its claims.

In 1908, with the Phelps Dodge owners no longer alive, the company was re-organized as a public company and the name changed to Phelps Dodge Corporation, a holding company for all of the various properties and operations. Dr. Douglas was its first president.

Labor relations The company became notorious for its anti-union tactics, primarily for the 1917 Bisbee Deportation. The company worked with a local group of private citizens and the county sheriff to deputize about 2,000 members of a posse. Given names of Industrial Workers of the World (IWW) members and other miners, they arrested nearly 1,300 striking miners at gunpoint in an early morning raid at Bisbee, Lowell and Warren. Portraying those affiliated with the IWW as bent on war-related sabotage, the company ordered them expelled from the jurisdiction, deporting them to Hermanas, New Mexico. Company officials and Sheriff Harry C. Wheeler seized telegraph and telephone lines to keep news of this from getting out. The Phelps Dodge copper mine at Morenci, Arizona was the site of a violent strike from 1983 to 1986, culminating in one of the largest union decertifications in American labor history.

Worked examples

Example 1 — a first encounter with Phelps Dodge

Start with the simplest possible case. Write down what Phelps Dodge 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 Phelps Dodge 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 Phelps Dodge 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 Phelps Dodge

In research
Phelps Dodge 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 Phelps Dodge 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
Phelps Dodge is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1834 establishments in New York (state), 2007 mergers and acquisitions, American companies disestablished in 2007, so understanding it makes those chapters shorter.
In everyday life
Look for Phelps Dodge 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.
