What's the general process for the initial separation of unwanted dirt? I've worked in a zinc smelter a long time ago, the initial stage was roasting, heating the ore to 900C to burn off unwanted components (such as sulfur, which went on to become sulfuric acid), and to melt other components.

I guess I'm surprised at the absence of flue stacks and cooling towers at the facility shown in the video.

Perhaps the facility in the video only shows "cleaner" downstream processing for marketing appeal, or separation processes are fundamentally different?

60 Minutes had some coverage of the beneficiation plant.[1] For rare earths, that's mostly grinding and sorting by density and magnetic properties. It's a large plant near the mine. Bags of rare earth ore worth about $120,000 per pallet come out, and those are transported to the Texas location for the next step, which has a lot more heat and chemistry.

MP is well positioned in the REE processing space -- now if the share price would stop collapsing then companies in the critical minerals sector would be able to raise capital more easily (MP is the bellwether for the sector)

Right. Since the 1980s, the Mountain Pass mine has gone bankrupt and shut down twice. Not because they did anything wrong, but because the prices of rare earths temporarily dropped below their production cost. Here's a general rare earth price graph.[1] It's tough having a business with fixed costs with a 10:1 price variation.

MP Minerals is now getting subsidies from both the U.S. Government and General Motors, both of which want a reliable source of magnets outside China. There are other sites in the US and Australia which could be developed if it was profitable. (Operating in Greenland, per Trump, is silly. The costs of operating anything big there are very high. No roads, no infrastructure, only a few months a year of ice-free construction time...)

Thanks. Now MP is on my radar.

Certainly at $41, a 52 week low, it's a fire sale (hit $100 back in October.
