ascends from the rock mass. Left behind are crystals of the minerals olivine and pyroxene which have a higher melting point (about 1000 C). Once that melting point is reached a basaltic magma forms. In this way the less dense felsic minerals, which could contain metals of economic interest, are separated fromthe heavier minerals in a rock mass.

The name pyrite comes from pyrite lithos, which, in Greek, means 'stone which strikes fire' in reference to the tendency of the mineral to spark when struck against steel. In fact, pyrite was used for that purpose in early flintlock rifles.
mineral processing challenges. The most critical relates to the difficulty in floating tailings pyrite resulting from a base-metal flotation circuit where pyrite is already depressed. Current mineral processing treatments consist in grinding sulfur-rich ore at a high pH (above pH 10), using lime (CaO) or caustic soda (NaOH).

Pyrite: The Real Story Behind “Fool’s Gold”. Pyrite is called “Fool’s Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite’s streak is brownish black.
Pyrite (FeS 2) is the most abundant metal sulfide associated with the earth’s surface region, which is commonly considered as ‘Fool’s gold’. Pyrite is frequently found in massive hydrothermal deposits, sedimentary beds, veins and replacements, and igneous rock, its reserve is ample and luxuriant, to some extent .

Pyrite is a very common mineral, found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks. The brassy-yellow metallic colour of pyrite has in many cases lead to people mistaking it for <M>Gold</M>, hence the common nickname 'Fool's gold'.
