amrclearinghouse.org AMD Basics PYRITE REACTIONS

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.

Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.

Pyrite Mineral Uses and Properties

Pyrite Mineral Uses and Properties

Pyrite and Coal Mining Sulfur occurs in coal in three different forms: 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from ...

The drilling of the Rio Tinto basement has provided evidence of an underground microbial community primarily sustained by the Fe and S metabolism through the biooxidation of pyrite orebodies. Although the gossan is the microbial activity product, which dates back to the Oligocene (25 Ma), no molecular evidence of such activity in the past has been reported yet.

Apr 20, 2021 For underground mining, geologists perform ore grade control to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. There is a need to check first as ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others.

Effects of pyrite on the spontaneous combustion of coal

Sep 28, 2015 The results indicate that pyrite can nonlinearly accelerate the process of spontaneous combustion. The coal sample with a pyrite content of 5 % has the largest CO release rate and oxygen adsorption as well. However, the coal sample with a pyrite content of 7 % has the largest rate of heat flow according to the results from the DSC tests.
