Pyrite - Wikipedia
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

Slurry - Density - Engineering ToolBox
Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density of liquid without solids (lb/ft 3, kg/m 3)
