Piedmont Lithium is a earth 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 Piedmont Lithium rather than just read about it. In short: Piedmont Lithium is an American mining company in the process of proving economic mineral recovery of lithium at sites in North Carolina, Tennessee, Canada, and Ghana.

Reference excerpt

Piedmont Lithium is an American mining company in the process of proving economic mineral recovery of lithium at sites in North Carolina, Tennessee, Canada, and Ghana. The company has done business deals with Tesla and is planning to invest in a $1.8 billion mine in Gaston County, North Carolina. The Gaston County project is one of multiple projects that Piedmont Lithium is working to develop currently. The surrounding Gaston County community is concerned that the mine will affect their water and air quality.

Background "The modern lithium-mining industry started in this North Carolina region in the 1950s, when the metal was used to make components for nuclear bombs. One of the world’s biggest lithium miners by production, Albemarle Corp, is based in nearby Charlotte. As of March 2021, nearly all of Albemarle's lithium is extracted in Australia and Chile, which have large, accessible deposits of the metal." As of 2021, just one percent of global lithium supply is both mined and processed in the United States (3,150 t (6,940,000 lb)), while 233,550 t (514,890,000 lb) is produced in Australia and Chile. Lithium is classified as a critical mineral by the US department of energy, as “it is the major ingredient in the rechargeable batteries found in electronics”. Piedmont Lithium president and CEO Keith Phillips stated his goals with the mineral are, “to be a leading supplier of lithium resources to the growing EV [electric vehicle] and stationary storage supply chains”. The demand for lithium has shifted in turn towards consumer electronics since the beginning of the modern lithium-mining industry. This demand is only predicted to increase in the coming decades.

History Piedmont Lithium Ltd was founded as an Australian company in 2016. Cofounders included Australian financier Taso Arima and US geologist Lamont Leatherman, who raised several million dollars of seed funding to start the firm. Arima read about the prospecting work Leatherman had done in the Gaston County, North Carolina area. Leatherman had explored the area for lithium in surface rock in the late 2000s after thinking back to "the green-striped rocks in the yard of his childhood home in [the area]. The rocks contained rich veins of lithium."

Projects Elevra Lithium currently has mining related projects in Quebec, Ghana, and Gaston County, North Carolina. The projects in Quebec, dubbed “North American Lithium” and “Moblan” respectively, contain an open-pit mine and spodumene concentrator. “Ewoyaa Lithium Project,” located in Ghana, aims to open “one of Ghana’s first lithium-producing mines”. The project in Gaston County, known as “Carolina Lithium,” is set to include an open-pit mine, spodumene concentrator, and a lithium hydroxide conversion plant.

Carolina Lithium Project The Carolina Lithium project in Gaston County is currently in development and will include a 1.2 billion dollar mine and processing plant. In preparation for the project, Piedmont Lithium began buying land, eventually accumulating to 3,600 acres. The mining project is currently in a negotiation phase as Piedmont Lithium needs to obtain air and water permits as well as a rezoning approval from Gaston County in order to continue to develop the mine. Piedmont Lithium's Gaston County project proposal predicts that “33,000 tons of lithium [will] be mined per year” and will produce “330,582 tons of greenhouse gas emissions annually," which is “equivalent to emissions from 66,000 gas-fueled passenger cars". The proposal states that the project will produce “169 tons of particulate matter” and“ 69 tons of the [particulate matter will be] PM 2.5”. According to the proposal, the Carolina Lithium project will operate on 3,600 acres of land which Elevra will use “half [of the land] as a buffer, and the other half, [as a] mining operations proper”. The company plans to have the Carolina Lithium mining operation as both a mining site as well as spodumene processing plant, “one of the few of its kind in the United States”. The mine is predicted to be in operation for 11 years and is expected to bring in large amounts of profit for the company according to Piedmont Lithium CEO Keith Phillips. The mine in Gaston County will be an open-pit Lithium Mine. Open-pit mines create mining waste which includes, but is not limited to thousands of tons of sulfuric acid per day as well as radioactive uranium extracts. Piedmont Lithium claimed implementation of multiple environmental risk mitigation features in their proposed mine. These features include a conveyor belt to transport blasted rock from the mine up to the processing plant and the usage of many tons of water to prevent dust from building up. On April 15, 2024, the company obtained the final permits they needed to build the Lithium Mine. The permits were approved “despite widespread opposition from neighbors worried about water, noise pollution and other potential problems”. Currently Elevra Lithium is waiting on rezoning approval from the Gaston County Board of commissioners to begin the project.

Worked examples

Example 1 — a first encounter with Piedmont Lithium

Start with the simplest possible case. Write down what Piedmont Lithium claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Piedmont Lithium 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 Piedmont Lithium 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 Piedmont Lithium

In research: Piedmont Lithium appears in earth 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 Piedmont Lithium 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: Piedmont Lithium is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 establishments in Australia, American companies established in 2021, Environment of North Carolina, so understanding it makes those chapters shorter.
In everyday life: Look for Piedmont Lithium 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.
