Many of those tiny blobs were long thought to be bits of graphite—like diamond, another form of pure carbon—and were thus cut away and discarded by jewelers. But inclusions in 38 of the 53 diamonds, or about 72%, were a graphite-coated mix of metal-rich minerals that also contained an alloy of iron and nickel.

How are diamonds separated from ore?

The heavy minerals, including diamonds, are separated from waste material based on their density differences in a dense media separation process. In this process, ore is mixed into a ferrosilicon slurry, then fed to a dense media cyclone, where the heavy minerals are separated from the waste.
