    Pyrite (Marcasite) ~ Learning Geology

    Marcasite tends to be lighter in colour, and is sometimes referred to as "white iron pyrite". Sometime marcasite has a greenish tint, or a multicoloured tarnish that is the result of oxidation. But marcasite has an unstable orthorhombic crystal structure and is liable to crumble and break apart.

    Many conventional comminution tests have some reliability issues related to small changes in rock mineralogy, texture and/or particle size. Mineralogical data correlated with conventional comminution tests offer two major improvements: control of test data and the capability to perform mineralsrelated comminution profiles on large, statistically more robust sample populations with rapid and lowercost .
