SPONGE IRON – Lloyd's Metals
Sponge iron making is a process in which iron ore lumps (typically 5mm18mm size) are tumbled with a 'select' grade of ironcoking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished product bunkers prior to dispatch....
Phosphorus
The phosphorustoiron ratio in material from the supernova remnant could be up to 100 times higher than in the Milky Way in general. In 2020, astronomers analysed ALMA and ROSINA data from the massive starforming region AFGL 5142, to detect phosphorusbearing molecules, and how they are carried in comets to the early Earth....

Iron ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ......
List of Foods Low in Phosphorus |
Regular dairy products are high in calcium, protein, fat and phosphorus. But there are some exceptions: butter, cream cheese, sour cream and margarine are lowphosphorus foods. Alternatives to cow's milk, soy milk and unenriched rice milk are also low in phosphorus....

Phosphorus in Soil and Plants
· PHOSPHORUS UPTAKE BY PLANTS. Plants take up phosphorus from the soil solution as orthophosphate ion: either HPO42 or H2PO4. The proportion in which these two forms are absorbed is determined by the soil pH, when at higher soil pH more HPO42 is taken up. The mobility of phosphorus in soil is very limited and therefore, plant roots can take up ......
