p-tert-Butylcalix[4]arene is a bowl-shaped molecule capable of forming a range of polynuclear metal clusters under different experimental conditions. p-tert-Butylcalix[8]arene (TBC[8]) is a significantly more flexible analogue that has previously been shown to form mono- and binuclear lanthanide (Ln) metal complexes. The latter (cluster) motif is commonly observed and involves the calixarene ad...

The recent development in remote sensing imagery and the use of detection feature spectrum information together with geochemical data is very useful for surface element quantitative inversion study. This aim this article to select appropriate methods that would make it possible have rapid economic prospecting. Qishitan gold polymetallic deposit Xinjiang Uygur Autonomous Region, Northwest China ...

SUMMARY Southeast China is one of the most important polymetallic metallogenic provinces in world. However, distinct differences type and origin mineral deposits are present between major belts this province. To deepen our knowledge regional setting, investigate factors controlling its explore feasibility active passive seismic imaging, we performed a multibatch experiment using sources with he...

Renewable energy installations and storage solutions require significant quantities of critical raw materials such as nickel, cobalt rare earth metals. The supply chains these face many difficulties, the continuous decrease mineral ore grades on land. In view complications, motivation to search for new resources has grown, with deep sea being seen a potential source minerals. Polymetallic nodul...

Abstract This paper aims at contributing to a better understanding of the beginnings tin and bronze metallurgy in Central Asia by investigating hitherto unique piece slag. The object was originally discovered as stray find only 4 km away from large copper-tin deposit Mušiston Tajikistan. It contains many prills copper well small charcoal particles. Radiocarbon dating places slag period between ...

The other-race effect (ORE) in face recognition refers to better recognition memory for faces of one’s own race than faces of another race—a common phenomenon among individuals living in primarily mono-racial societies. In this article, we review findings suggesting that early visual and sociocultural experiences shape one’s processing of familiar and unfamiliar race classes and give rise to th...

3D geological modeling of lithogeochemical and geological data provides insight into the role of the sulfide ore horizon and associated footwall hydrothermal alteration in localizing shear strain in the Flin Flon volcanogenic massive sulfide deposits, Canada, as deformation evolved from brittle-ductile to ductile regimes during collisional stages of the 1.9–1.8 Ga Trans-Hudson orogeny. 3D spati...

Th is study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic n ickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are ...

Conventional gravity separation process of iron mineral fines is not very effective. In present work Multi Gravity Separation (MGS) process has been studied. This study was performed on a low-grade iron ore namely goethiticlateritic ore (GLO) from Eastern India. Detailed mineralogical, physical and chemical characteristics of a goethiticlateritic iron ore showed that the sample contained porous...

Mining and ore processing activities are associated with changes in the surrounding environment and may pose a risk to human health, if adequate safety measures are not taken. The uranium ore generally varies worldwide between 0.03 – 3% U3O8, except for a few deposits where higher levels of uranium is reported. More than 95% of the ore is converted into waste material called “tailings”. Around ...
