Oct 05, 2016 A Bessemer ore carrying 52 of iron must not have than .052 of phosphorus and the sulphur should not exceed .04 . But since the presence of phosphorus in pig iron increases the fluidity and tends to make sound castings, ores high in phosphorus are used in.Read More
In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.
Most of the phosphorus compounds were not reduced in the low temperature reduction process of high phosphorus iron ore and remained as oxides in the gangue phases. The gangue phase size increased.Read More
Sep 01, 2010 A new method (gas-based separation plus melt separation) has been proposed to remove phosphorus of the high phosphorus iron ore which was 1.25 of phosphorus content and 50.0 of iron content.

Mar 11, 2021 Phosphorus iron also known as iron phosphide is made of phosphate ore and iron ore smelting in the blast furnace. It is a symbiotic compound containing 20-26 phosphorus and 0.1-6 silicon, which can change the corrosion resistance and chip resistance of steel.
The Englishman Sidney Gilchrist Thomas`s invention permits the production of steel from high phosphorus minette iron-ore from Lothringen (Loraine). Minette means minor ore , which has an iron content of only around 30 . 1883. The first blast furnace.Read More
Chemical composition of the high phosphorus iron ore (Hamersley) used in this investigation (mass ). as-received iron ore samples were carried out using a cop-per Ka X-ray source with a nickel monochromator. The scans were measured from 2q 0 –90 at a rate of 4 min.
High-phosphorus iron ore is traditionally dephosphorized by chemical process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent environmental pollution. With the current tendency for development of a low-cost and eco-friendly process, deph.Read More
