By vibrating particles, researchers at Columbia Engineering reveal the normally chaotic motion of bubbles traveling through such particles can become orderly, findings that could one day help make mining more sustainable.
A new way to control the motion of bubbles from researchers at Columbia Engineering might one day help separate useful metals from useless dirt using much less energy and water than is currently needed.
When mining for metals such as the copper used in most electronics and the lithium used in many batteries, only a small fraction of the material that is mined is useful metal, with the vast majority just useless dirt-like particles.
In this video, Chris Boyce, assistant professor of chemical engineering, and his colleagues explain how vibrating particles can help control the motion of bubbles, which could help lead to more sustainable mining practices.
“We have to separate the useful metals from the useless particles, and we do this by blowing air bubbles up through them,” said Chris Boyce, assistant professor of chemical engineering at Columbia Engineering. However, “this process utilizes a large amount of energy and water, causing climate change and water shortages, thus creating problems we are trying to prevent. We have this issue in part because we currently cannot control the motion of these bubbles.”
I think the simple addition of vibration to go from chaos to order is beautiful.

Now Boyce and his colleagues reveal that if they vibrate these particles while blowing air up through them, the normally chaotic motion of these bubbles becomes orderly and controllable. The vibrations cause the particles to quickly shift between solid-like to fluid-like behavior, which in turn helps structure the bubbles into regularly spaced triangular arrays.
“I think the simple addition of vibration to go from chaos to order is beautiful,” Boyce said. Their study appears August 23 in the journal Proceedings of the National Academy of Sciences.
Having a way to control the behavior of these bubbles can help scale up and optimize separation techniques. “We expect that the ability to create structure in flows can reduce energy and water use in mining as well as improve the efficiency of many clean energy processes,” Boyce said.
The researchers now aim to apply this structured bubbling to sustainable mining separation techniques.
