The rugby ball and nanodiamond shaped nanoparticles did not reach magnetic saturation at the maximum magnetic field of 50 kOe. The rugby ball shaped hematite particles (~178 nm) display magnetic behavior similar to that of bulk hematite (~3 µm; weakly ferromagnetic [10,11,12]) at room temperature [11, 26].
Arsenic contamination and its removal from the ground or natural water become an inevitable research line as it is highly carcinogenic and toxic. In the last few decades, nanotechnology has been achieved to provide accessible clean water for all living organisms. In this work, the various ratios of TiO2/γ-Fe2O3 nanocomposite (T/M NCs) synthesized using the …

Sulfur dioxide is a colorless gas with a pungent odor. It is a liquid when under pressure, and it dissolves in water very easily.Sulfur dioxide in the air comes mainly from activities such as the burning of coal and oil at power plants or from copper smelting. In nature, sulfur dioxide can be released to the air from volcanic eruptions.

This is a Hematite streak and not a meteorite streak. Since the dawn of man's history, the red powder of hematite has been used as a pigment by humans. Although the rock may be dark brown or grey on the exterior, the powder when ground up will be red. The picture shows a diamond file has been used to test a piece of rock.
Anisotropic or non-spherical geometry is known to be entwined with various parameters and has a significant outcome on the physical, chemical, and physiological properties of the particles [,,, ].Accurate control of their morphology has a direct impact on their characteristics which are essential for various physicochemical and biomedical applications.
An novel approach for determining grinding media system of ball mill was proposed. • The optimum media ball size of three size fraction samples were obtained. • The media size ratio was ascertained as φ 50 mm: φ 40 mm: φ 30 mm = 28%: 28%: 44%. • The installed power and productivity of ball mill (Φ5.03 m × 6.40 m) were calculated.

Technologies for remediation of wastewater by industrial solid waste have recently attracted interest. Acid mine drainage is an extraordinarily acidic and highly heavy metal ions contaminated leachate which posed some challenges for the environment. Nonetheless, steel slag shows significant potential application prospects in wastewater treatment, due to its excellent …
iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite …
Earth Has 'Blueberries' Like Mars. June 16, 2004 — Even before marble-shaped pebbles nicknamed "blueberries" were discovered on Mars by the Opportunity rover, University of Utah geologists studied similar rocks in Utah's national parks and predicted such stones would be found on the Red Planet. In a study published in the June 17 ...
