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 ...

To achieve the utilization of fine ilmenite (especially ?0.075 mm) produced in titanium-magnetite processing plant Panzhihua, a radial turbulent outer-cylinder magnetic separator (RTOCMS), was developed this study. After optimizing conditions rotation speed and water flow, an RTOCMS concentrate with TiO2 grade 22.84% recovery 66.93% obtained through one-stage roughing pre-concentration flowshee...

Through thermodynamic smelting experiments, nonisothermal and isothermal kinetics the effects of CO2–containing gas injection on chromia–bearing vanadiferous titanomagnetite ore were investigated. The experiments at 900 °C, 1000 1100 1200 1300 CO2 concentration 0, 10 vol.%, 20 30 vol.% studied. samples after analyzed through calculations characterized by XRD, XRF, XPS, SEM. results show that si...

introduction there is an iron mining complex called shahrak 60 km east of takab town, nw iran. the exploration in the shahrak deposit (general name for all iron deposits of the area) started in 1992 by foolad saba noor co. and continued in several periods until 2008. the shahrak deposit comprising 10 ore deposits including korkora-1, korkora-2, shahrak-1, shahrak-2, shahrak-3, cheshmeh, golezar...

Using ethyl paraben as the template molecule and n-tetrabutyl titanate titanium source, molecularly imprinted dioxide (MIP-TiO 2 ) photocatalyst was prepared by sol-gel method. The effects of different pH values, imprinting molecular weights other factors on degradation were studied, materials analyzed TEM, XRD, FT-IR characterization methods. results show that catalyst has a mixed crystal stru...

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 ...

In the 17century, German miners discovered a red coloured ore they believed to contain copper. They discovered upon analysis that there was no copper but that a useless, smelly material was actually present. Thinking the ore was evil they dubbed it "Kupfernickel" or Old Nick's Copper, which meant false or bad copper. Swedish scientist Baron Axel Frederich Cronstedt in 1751 finally isolated nick...
