摘要

Iron pyrite (FeS2), commonly known as 'Fool's Gold' is ubiquitous in nature. It frequently occurs in underclays of coal seams, shales, sedimentary rocks including some limestones. As an accessory mineral it is associated with igneous and metamorphic rocks. Nanostructures of iron pyrite are continuously synthesized in the quartz veins and hydrothermal vents. It is either mined or comes out as waste products from the coal mining operations. It exists in several forms depending on its origin and crystallinity. Most of the naturally occurring pyrite has several impurities including arsenic, antimony, copper, lead, zinc, calcium, aluminum, bismuth, cobalt and phosphorous. Till date, in agriculture industry, naturally occurring pyrite is partially purified, and used as a fertilizer to supply iron (Fe) and sulfur (S) to the crops, and as an ameliorating agent to reclaim alkaline soil.
