Duck-Duck-Go WS2, Tungsten DiSulfide and it's friction reduction properties as a coating amazing stuff. JMHO one of the next cutting edge arena's besides 3D printing, Graphene, etc will be friction reduction.
Our deep is the deposit ?
Tungsten is critical to the making of fake gold bars.
Thanks for posting. I had the pleasure of visiting the Hemerdon mine site as a side-trip arranged by my boss when I worked for AMAX Inc back in 1981 as a semi-boondoggle to pay for a honeymoon trip to Europe so that my bride and I could both be in Europe at the same time. She was auditing the European subsidiary of AMAX Inc. at the time.
AMAX has just one employee, a mine engineer, working full-time on-site at the time. After our “tour” of the mine site (five minutes looking at an undeveloped area) He took me for a sail around Plymouth harbor in his little sailboat on in a drizzle that was supposed to be a pretty good day in those parts.
It was only a semi-boondoggle as to the particular timing as the mine was in my portfolio of responsibility as the Tungsten analyst for the Climax Molybdenum Division of AMAX Inc.
I am very glad to see that somebody woke up and said “Hey wait, what if the Chinese cut off our Tungsten supply?” (and a whole lot of other metals and rare earths needed for microelectronics, jet and rocket engines, etc.)
