Feb 03, 2010· Feb 03, 2010· Pyrite oxidation and AMD generation are important processes that may take place within the wastes produced by coal mining and coal washing operations in the Golestan province (northeast Iran). The study area is characterized by appropriate atmospheric conditions that favor pyrite oxidation and the presence of a large amount of water bodies.

Sep 26, 2021· Sep 26, 2021· Iran lies in the Alpine-Himalayan orogenic belt and evolved by the opening and closing of the Paleo-and Neo-Tethys Oceans (Berberian and King 1981; Bagheri and Stampfli 2008; Masoodi et al. 2013).The Iranian Plate is considered to have separated from the Eurasian Plate by the Paleo-Tethys Ocean during the Late Ordovician to Early Silurian (Nataľin and Şengör 2005).
Jul 20, 2005· Archeological surveys indicate that Iran was among the leading nations in mining activity in ancient times (ʿAlipur, 1993-94). Its ancient civilizations, richness of natural resources, and records of ancient mining and metalworking are testimonies to such a claim (Zāvoš, 1976-77). The history of mining in Iran can be divided into two periods.

Jul 16, 2013· Jul 16, 2013· The enhancement of sulphide minerals' oxidation principally pyrite (FeS 2) by mining activities is a worldwide problem. The Sarcheshmeh copper mine, in Kerman province, southeast Iran, provides a great opportunity to investigate the processes involved in sulphide mineral oxidation and AMD generation within sulphide-bearing tailings.
This paper investigates pyrite oxidation and related environmental problems associated with the sulphide mine tailings dam produced by the copper processing plant at Sarcheshmeh mine in Kerman, Iran.
The source of pyrite and pyrrhotite electrodes was pure and bulk specimens of the minerals. Pyrite, pyrrhotite, and steel were selected from a Mexican mine, Wards Institute (Canada), and the steel mill balls of Chadormalo iron mine in Iran, respectively. The type of steel used in this experiment was 70Cr2.
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP.
Sep 26, 2021· Sep 26, 2021· Pyrite is fine-grained (0.03–0.5 mm) and occurs as euhedral and/or subhedral grains disseminated in host rock and among other minerals (Fig. 6a–d). ...
