The mineralized shear zones in the Arcturus mine are characterized by silicification, biotite, and Kfeldspar alteration. Gold mineralization is associated with pyrrhotite, arsenopyrite, and also occurs as free gold, which contributed up to 10% of production. There are 6 major reefs at Arcturus: Venus, Arcturus, West, Slate, Saturn, Planet.

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.
