The efficient separation of ilmenite is a difficult problem in minerals flotation. For this issue, α-aminooctyl phosphinic acid (APA) was developed as selective collector to separate ilmenite. flotation test result showed that APA more for improving recovery compared with octylphosphonic (OPA). Adsorption, ZETA and FTIR measurements proved the chemical interaction between surface stronger than ...

Inside the finest fractions of aggregates, usually wasted by ready mix concrete companies, valuable heavy minerals content is substantial. The concentration and recovery contained in dredged fine aggregates waste, located Pyeongtaek South Korea, were investigated to develop a process that can recover concentrate most each mineral. raw material contains ilmenite, magnetite, monazite, zircon. A g...

Micrometeorite impacts and solar wind irradiation, the dominant space weathering (SW) processes, largely modified compositions microtexture of soil materials on Moon. Here, we report SW characteristics Chang'e-5 lunar soils from mid-high latitude (43.06°N). All mineral phases exposed surface a single basalt clast have vapor deposit layer, whereas textures irradiation-damaged zone are dependent ...

The Titanium (Ti) isotope compositions of felsic rocks are heavier than their mafic counterparts, and alkaline magmas develop Ti compared to other magma series during magmatic differentiation. Both observations interpreted reflect the preferential sequestration light isotopes in Fe-Ti oxides, such as rutile, ilmenite titanomagnetite. However, interpretations so far rely on whole rock studies co...
