Coal-based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus-containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction proc...
The interplay of hydrological, chemical and microbial processes in the formation of iron-rich floating films in aquatic environments at a circumneutral pH The direct contribution of microbial activity to the formation of iron-oxide minerals is difficult to prove in wetlands due to the high reactivity of solid iron phases with different compounds and the variety of redox processes that may occur...
It is well established that an increase in iron supply causes an increase in total oceanic primary production in many regions, but the physiological mechanism driving the observed increases has not been clearly identified. The Southern Ocean iron enrichment experiment, an iron fertilization experiment in the waters closest to Antarctica, resulted in a 9-fold increase in chlorophyll (Chl) concen...
Stellar winds from fast-rotating Population III (Pop III) stars have long been suspected to make important contributions early metal enrichment, as features in the nucleosynthesis of such `spinstars' are consistent with chemical abundance patterns some metal-poor local Universe. Particularly, stellar rich light elements can provide another pathway towards explaining carbon enhancement carbon-en...
Backround & Objective: Iron deficiency anemia is a major public health problem worldwide, particularly in developing countries. Women especially during reproductive life are vulnerable group. Around 1/3 of the worldۥs population suffers from anemia and nutritional deficiency is to blame as the most significant factor. About 350 million women and 50% of the children in developing countries are a...
