AbstractExperimental studies of pyrite oxidation over the pH range 6-9 were carried out at 30°C in 0.1 M KC1 under conditions of fixed pH and p02. Rate of addition of base necessary to maintain a fixed pH was monitored. Samples were withdrawn periodically and analyzed for total sulfur in solution, thiosulfate, polythionates, and sulfide.Cited by: 4

Feb 02, 2010 · Pyrite is also exceptionally dense, with a specific gravity of 5.0 to 5.2. Only hematite has a higher density. Marcasite tends to be lighter in color, and is sometimes referred to as "white iron pyrite". Sometime marcasite has a greenish tint, or a multi-colored tarnish that is the result of oxidation. But marcasite has an unstable orthorhombic ...
