Separation of P Phase and Fe Phase in High Phosphorus ...

Jul 22, 2015· The high phosphorus iron ore is a typical complex resource, which contains a high content of iron, but it is hard to be used due to the presence of phosphorus and its special oolitic structure.[1–3] In high phosphorus iron ore, the apatite phase and hematite phase are so intimately intermixed,[4,5] which makes it hard to grind the ore to a ...

Phosphorus Removal of High Phosphorus Iron Ore by Gas ...

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. HSC chemistry package and the coexistence theory of slag structure were adopted for theoretical analysis.

REMOVAL OF PHOSPHORUS THROUGH ROASTING OF …

(1966). The phosphorus content in the iron concentrate is about 0. 6 – 0.8 % and the studies has shown that it is not represented as separable from iron minerals species, Belikov . et al (2002), Ionkov . et al (2011) but is included in limonite as a solid solution. Attempts for physical separation of phosphorus from similar Australian iron ore

(PDF) Microwave Assisted Liberation of High Phosphorus ...

Jan 01, 2014· The influence of microwave treatment on the liberation of iron ore from the high phosphorus oo-litic iron ore from Aswan region, Egypt was studied.

A novel direct reduction-flash smelting separation process ...

Jan 02, 2021· The iron ore with high phosphorus content is a common complex symbiotic iron ore species, and it is widely distributed in the United States, France, Russia, Australia and China [, , ]. Most of this type of ore presents an oolitic microstructure [ 1 ].

Phosphorus Removal of High Phosphorous Oolitic Iron Ore ...

A process with acid leaching followed by hydrogen-based fluidized reduction and melt separation is presented for recovering DRI (direct reduced iron) from high-phosphorus oolitic hematite in this study, and the aim of this study is to provide theoretical and technical basis for economical and rational use of high phosphorus oolitic iron ores.

Characterization studies on Agbaja iron ore: a high ...

Feb 02, 2019· Iron ores with phosphorus content lower than 0.07% P are commercially desired as they are suitable for use in iron production. As a consequence, a lot of research efforts have been focused on phosphorus removal from high-phosphorus iron ore [20, 24, 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48] in a bid to reduce the P content to acceptable …

Separation of P Phase and Fe Phase in High Phosphorus ...

reduction of oolitic iron ore with phosphorus content of 0.24 wt pct and followed by wet milling and magnetic separation, the extracted iron has an iron grade of

Processes for phosphorus removal from iron ore - a review

During the reductive calcination, Na 2 CO 3 reacts with gangue minerals (SiO 2 and Al 2 O 3) forming phosphorus-containing aluminum silicate and modifying the structure of the mineral, promoting the separation of iron and phosphorus during magnetic separation. The composition of iron concentrate obtained: 64.12% Fe and 0.07% phosphorus with an ...

Separation of P Phase and Fe Phase in High Phosphorus ...

Due to the oolitic structure of the high phosphorus iron ore and the closely wrapping of apatite and hematite phases, an approach using jet mill was utilized to grind the ore to ultrafine 0.01 to 0.001 mm, which realizes the dissociation of apatite phase and hematite phase. Then in a laboratory scale rotary furnace, high phosphorus ores of different sizes were reduced by reducing gas at sub ...
