Aluminum (AI) toxicity is known to cause microcytic anemia, osteomalacia, and encephalopathy, but the mechanisms are poorly understood. Although Al is a neurotoxicant, its role in Alzheimer's disease remains controversial. One hypothesis for the toxicity of Al is that it disrupts cellular iron (Fe) homeostasis, causing iron to become cytotoxic. Cell culture studies have shown that Al suppresses...

The current version of the Tax Code allows for misinterpretation interpretation term "primary processing mineral resources". In particular, tax authorities believe that primary raw materials includes magnetite concentrate, which in this case is subject to taxation. That is, a number mining and enterprises have faced problem double taxation, threatens significant financial losses. Accordingly, l...

In this paper, iron ore sample from the Chadormalu was investigated to determine some comminution properties. Chadormalu deposit is one of the largest iron ore mine in Iran, which is located in Yazd province. The representative ore sample contained 57%Fe, 0.9%P and 0.17%S. The sample was crushed; afterward, it was ground in various grinding times according to the Bond Ball mill approach to spec...

Comminution is an essential step in processing itabirite ores, given the need to liberate silica and other contaminants from iron minerals for downstream concentration then pellet feed production. In general, these ores Brazil are not particularly hard crush grind, but both capital (CAPEx) operating (OPEx) expenditures this stage of preparation can be critical project, particular due uncertaint...

This paper present the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differing iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi mines, Jharkhand, India, certain spectro-radiometric measurements and geochemical analysis were carried out and the results have bee...

This case study utilizes a value of information decision framework to provide mine managers guidance regarding the purchase of ore grade scanners. LKAB’s Kiruna mine produces three types of iron ore to meet long-term contractual agreements on a monthly basis. There is a priori uncertainty regarding the ore type in any given mineable section of the orebody. In addition, there is extracted ore ty...

Investigations were conducted to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with gasohol (80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts of sponge iron and manganese ore and compared with ...

The recovery of fine hematite particles from banded hematite quartzite (BHQ) ore with potato starch has been investigated using selective flocculation. Microscopic features, coupled with x-ray diffraction (XRD), and Fourier transforms infrared (FTIR) spectroscopic data provide evidences for adsorption of starch molecules on hematite surface. The starch molecules show good selectivity for hemati...

Iron ore sintering processes constitute significant sources of dioxins, and studies have confirmed a close correlation between polychlorinated naphthalenes (PCNs) and dioxin formation. Thus, iron ore sintering processes are thought to be a potential source of PCNs, although intensive investigations on PCN emissions from sintering processes have not been carried out. Therefore, the aim of the pr...
