As the scheelite Eu anomalies were inherited from ore-forming fluids with variable redox conditions and pH, the complex dEu/Mo correlation indicates that Mo increasingly entered the scheelite under oxidizing conditions and reached a maxim at dEu values of 0.8 to 1. In contrast, under reducing conditions, Mo contents in scheelite …

of scheelite as an ecient indicator mineral for mineral exploration targeting. In both reduced and oxidized skarns systems, scheelite forms during prograde and retrograde stages. Prograde scheelite is texturally and chemically zoned, whereas ret-rograde scheelite is predominantly texturally homogeneous but may display chemical zonation.

The association between gold and scheelite in orogenic gold deposits has long been recognized. Goldfarb et al. review the characteristics of orogenic gold deposits.In many deposits, scheelite predates and/or is contemporaneous with gold deposition, such as in the Val-d'Or district, Canada (Beaudoin and Pitre 2005), at Mt. Charlotte, Australia …

Pumps are one of the most ubiquitous items of equipment found in chemical processing plants. Often, they are used to transfer hazardous liquids, such as flammable, combustible, toxic and corrosive chemicals. In order to ensure safety during pumping, certain design and operating practices should be followed. This article discusses safe …
According to Wikipedia, official sources say that, in 2013, as many as 4.76 million foreigners visited Iran and, since then, the country has increased massively in popularity, which means that the figure may have easily doubled or even tripled – just a guess. These statistics are just insane for Iran, especially if we take into account that the …

The trace element composition of scheelite from 19 well-documented reduced and oxidized skarn systems was measured by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to establish chemical criteria for the application of scheelite as an efficient indicator mineral for mineral exploration targeting. In both …
Bad weather may have been a cause of Sunday's crash that killed Ebrahim Raisi. But mechanical issues, possibly exacerbated by a lack of spare parts due to U.S. sanctions, could also be a factor.
The Sangdong W (tungsten)-deposit is known as one of the world's largest W-deposits, a magmatic–hydrothermal ore deposit including both skarn and hydrothermal alteration zones. The strata-bound characteristic of the deposit resulted in three major orebodies (hanging wall, main, footwall). The main ore mineral is a scheelite …

Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid-state lasing medium. It glows bright blue under UV light, and naturally is an orange color. Scheelite was first described in 1751 for an occurrence in Mount Bispbergs klack, Säter, Dalarna, Sweden ...
Scheelite (CaWO 4) is the main W-bearing mineral in porphyry and skarn W or W-Mo deposits.It can host many different trace elements by substitution for Ca 2+ and W 6+ in the mineral lattice (Ghaderi et al., 1999, Brugger et al., 2000, Dostal et al., 2009, Song et al., 2014, Poulin et al., 2016, Miranda et al., 2022), and its high Mo and LREE …
And Iran's repeated assurances about the safety of this plant have fallen on deaf ears because of widely reported concerns over the project's 37-year-long construction history and the high level of seismic activity in Iran. ... the Bushehr plant was shut down after a broken pump caused contamination of cooling water; the malfunction was ...
In 1978, Iran Industrial Pumps Co. has started manufacturing and construction of ISO pumps in the industrial city of Alborz. In 2001 and after many years of hard works, continuous effort and gathering lots of experience, the company was moved to Hashtgerd industrial city to improve its development and make more progress; and started the ...

For people worried about safety, I would say the only place in Iran to avoid is the province of Sistan & Baluchistan which borders Pakistan. It's a predominantly ethnically Baluchi and Sunni Muslim region of Iran, so they are an ethnic and religious minority in Iran. I've never been but there are often stories of kidnappings, militants …
