: Carbothermal Reduction of Boron-bearing Iron

resource of China. Boron-bearing iron concentrate is the intermediate product of the ore dressing process of crude low grade ludwigite and extracting boron from it has great effect on the total boron yield. Pre-reduction of the boron-bearing iron concentrate is one of the important steps of the pyrometallurgical boron and iron separation process.

: Removal of phosphorus from iron ores by chemical

2006-12-1 Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions. The results show that phosphorus occurring as apatite phase could be removed by alkali-leaching, but those occurring in the

2013-1-18 • Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

: Developing a Low Hazardous Method to Determine Fe

2021-11-5 The presence of iron sulfide minerals and the lack of dissolution of iron in these minerals in hydrochloric acid causes the titration results to be not accurate, and consequently, the obtained Fe grades to be less than the actual amount. In the proposed method, Fe–S bonds are broken in nitric acid and then iron is dissolved using hydrochloric acid. Increased safety and reduced analysis time ...
