A new resource has been discovered in Minnesota and it has huge potential to mine. A massive reservoir of helium has been discovered and it’s such a large volume that the global industry could be impacted. The deposit is located in the Babbitt region of St. Louis County, and it’s an almost sure bet that there are economic benefits on the horizon for the region’s economy.
Minnesota has new potential as a global helium supply leader
The new helium pocket in the State of Minnesota, which is in the midwestern part of the United States and borders Canada, is being described as one of the richest helium reserves ever discovered on Earth. If the reports about its volume are to be believed, the state is now poised to take a significant position in the worldwide helium production industry.
Helium has a wide range of applications across various fields and industries, such as medicine, cryogenics, technology, nuclear fusion research, specialized welding, and many more.
The richness of the Topaz Project is unprecedented
The company that discovered the rich helium deposit is Pulsar Helium, an exploration outfit based in Canada. The site is being referred to as the Topaz Project and experts have noted its unprecedented size. Exploratory drilling operations uncovered helium concentrations of between 8.7% and 14.5%, which far exceeds the normal concentration levels of around 0.3%. Pulsar Helium company is currently evaluating the site’s full production potential.
Minnesota may soon join countries like Tanzania, Russia, and Qatar as major players in the helium market. The size and concentration of the helium reservoir suggest that commercial extraction may start soon, delivering employment opportunities and economic growth to the region.
Complex geological features led to the accumulation of helium
The Topaz Project is located along the Midcontinent Rift, a geological feature that formed more than a billion years ago. The rift has led to the formation of various kinds of mineral deposits, but this latest helium pocket appears to be the most promising yet. The latest seismic data shows the reservoir is even more expansive than initially thought, and excitement is starting to build among various stakeholders.
The Minnesota helium reservoir took an incredible 1.1 billion years to form and accumulate to such high concentrations. Two exploratory drilling operations to depths of 1,750 feet and 2,200 feet revealed significant gas deposits at both. The specific conditions needed for helium accumulation mean that such discoveries are rare, which is why this reservoir is attracting so much attention.
In news about a different resource discovery, Finland is on the road to becoming one of the energy-leading countries in the world with an estimated 20 million years’ worth of geothermal energy waiting to be harvested.
Helium extraction, processing, separation, and purification
There are specific mining techniques that will have to be utilized in the extraction of helium from the Topaz Project. A process of casing as a safety precaution is used in drilling operations to prevent contamination and blowout.
After extraction, the natural gas mixture, which contains helium, has to be separated from other gases like nitrogen, methane, or different hydrocarbons. Cryogenic distillation is applied in the first stage, a process necessary to cool the gas to extremely low temperatures.
The components are then separated by fractional distillation based on their different boiling points. When producing helium, this involves removing the gases that liquefy at higher temperatures.
Helium purification is the most important step in the process
The final step in the process of preparing the gas for the market is purification, which is essential to ensure a high-quality supply for commercial use. In Minnesota, the helium gas may reach levels exceeding 12.4% purity, meaning that output is going to be high.
Advanced pressure swing adsorption (PSA) and membrane techniques are two more techniques utilized to remove any remaining contaminants or impurities. This ensures that the helium is refined to the high purity level required for medical, industrial, and scientific applications.
It’s clear that the potential of the new Mnnesotan helium reservoir has not been exaggerated, and residents of the state and St. Louis County in particular can start preparing for an imminent economic boom.
Another potential new minable resource has been discovered in the U.S. and it could change the face of the country’s renewable energy transition. The discovery concerns lithium in the wastewater produced during fracking operations, a sector of mining with a notoriously bad reputation.
