Rampura Agucha is a zinc and lead mine located on a massive sulfide deposit in the Bhilwara district of Rajasthan, India. [1] [2] Rampura Agucha is located 220 km (140 mi) from Jaipur. It is north of Bhilwara, and northwest of Shahpura. Rampura Agucha is 10 km (6.2 mi) southeast of Gulabpura on NH 79. [1] The mine is owned by Hindustan Zinc ...
The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .
Sedimentary exhalative deposits ( SEDEX or SedEx deposits) are zinc - lead deposits originally interpreted to have been formed by discharge of metal -bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulfide minerals. [1] [2] [3] SEDEX deposits are hosted largely by ...
Phyllic alteration is a hydrothermal alteration zone in a permeable rock that has been affected by circulation of hydrothermal fluids. It is commonly seen in copper porphyry ore deposits in calc-alkaline rocks. Phyllic alteration is characterised by the assemblage of quartz + sericite + pyrite, and occurs at high temperatures and moderately ...
A polymetallic replacement deposit, also known as carbonate replacement deposit or high-temperature carbonate-hosted Ag-Pb-Zn deposit, [2] is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metal-bearing solutions in the vicinity of igneous intrusions. [3]
Pyrrhotite ( pyrrhos in Greek meaning "flame-coloured") is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.125). It is a nonstoichiometric variant of FeS, the mineral known as troilite . Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.
Rajasthan State Mines & Minerals Limited [1] (RSMML) is a public sector enterprise of the Government of Rajasthan and primarily engaged in Mining and Marketing of High Grade Rock phosphate, Lignite, Limestone & Gypsum (Non-Metallic minerals) through its mines located at various locations in Rajasthan. RSMML is a multiple location organization ...
This limit was kept in a comprehensive definition of 1981: "Massive sulfide deposits are strata-bound and in part stratiform accumulations of sulfide minerals which are normally composed of at least 60% sulfide minerals in their stratiform portions. The stratiform portion may comprise up to 100% of the total sulfide present, but many deposits ...
