Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4829-4840, September 2026.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4702-4718, September 2026.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

Synthesis of iron nanocomposite reinforced by TiC particles via mechanical activation from ilmenite concentrate and carbon black

Science and Engineering of Composite Materials, 2016
In this research, synthesis of Fe-TiC nanocomposites from activated ilmenite concentrate and carbon black was investigated. Ilmenite and carbon black as raw materials were milled in a planetary ball mill and sampled after different milling times.

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...

Effects of mineralogical composition into the reactivity of calcinated ilmenite for chemical looping technologies

Journal of Materials Research and Technology
Ilmenite is one of the most promising oxygen carriers (OC) for chemical looping combustion (CLC) on a large scale. However, ilmenite samples from distinct mines submitted to diverse mineral processing procedures do not have homogeneous physicochemical ...

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

Thermodynamic Controls on the Competition Between CO2 Solute Transport and Retention in Fracture‐Pore Media: Insights From Real‐Basalt Microfluidics

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Reactive‐surface exposure during basalt carbonation is controlled by the entry and retention of fracture‐transported CO2 solute within adjacent pores, yet these pore‐scale processes remain poorly constrained under reservoir temperature and pressure.
