3 reacts with fluoride salts to form water-soluble fluoroborates. The demineralized portion (typically 80 to 100 g of powdered bulk rock treated with acid yields ∼1 g of carbonaceous residue) of the Onaping rock was then put into an extraction thimble, placed into a Soxhlet apparatus, and refluxed with toluene for 24 hours The excess toluene was evaporated to dryness, leaving a small amount (microgram quantities) of residue. This residue was then redissolvad in toluene and concentrated to ∼1 ml, yielding a bright reddish solution.
