The price of iron ore, the main ingredient in steel, surged to its highest level in almost five years on an emerging shortfall from the world's mining hubs of Brazil and Australia.
Hydrometallurgy based dephosphorization of iron ore as observed from experiment and model prediction [35] has shown that phosphorus removal during leaching using oxalic acid solution, is highly dependent on the final pH of the leaching solution (which varies time .

A process is proposed for the dephosphorization of iron ore. The process consists of an integrated treatment for the removal of the phosphorus from the ore by leaching and further processing of the leach solution. Phosphoric acid is extracted by isoamyl alcohol (iAmOH) and stripped by nitric acid solution.
However, the acid converter steelmaking dephosphorization; lowphosphorus of the iron ore a serious impediment to the development of steel production. 1879 Thomas () invented the converter steelmaking method can handle the high phosphorus hot metal alkaline the dephosphorization principle of basic slag is then extended to the open ...
Jan 05, 2012· Dephosphorization of iron ore can be achieved through bioleaching. Different methods are needed to remove phosphorus from iron ore depending on whether it is present as a mineral (apatite) or associated with iron minerals ( Edwards et al., 2011 ).
Surprisingly, it was stated that agents according to this invention yielded a remarkable dephosphorization and desiliconizing and denitriding power, parallel to the desulfurization. Especially Na or Krich minerals like albit or Kfeldspar, and also Nabentonite, were very effective in connection with lime, ironore, chromiumore/or Manganeseore.

The first one was magnetic separation after grinding to % mm which facilitated % of P to be .... mechanically agitated glass reactor.
Results and discussion. The composition of iron concentrate obtained: % Fe and % phosphorus with an iron recovery of %, and a rate of dephosphorization of %. Figure 2 shows a flowsheet for concentration by reductive sintering and removal of phosphorus.
Abstract : A process has been proposed for the treatment of apatite apatite Subject Category: Chemicals and Chemical Groups see more details concentrate obtained from the dephosphorization of iron ore. In this process, the apatite is acidulated by HNO 3 to produce highpurity H 3 PO 4. The crude acid obtained is at least equivalent to, if not better than, the typical wet process acid.
dephosphorizing phosphorcontaining iron ore using bacteria, giving a yield of above 80% within 3045 days. In countries having high phosphorusiron ore, the highlighted dephosphorization process is capable of providing a reliable technical support; giving good dephosphorization at low cost.
process from dephosphorization (using DeP and DeC converters) in the duplex melting process is advantageous, as it allows for the use of phosphorusrich iron ore and relatively lower amounts of slag, as well as direct alloying with manganese ore in the converter. Consequently, iron procurement costs and metal losses are reduced to a ...
Meanwhile, Na 2 CO 3 also improves the growth of iron grains, increasing the iron grade and iron recovery. The iron concentrate, assaying % Fe and % P at the iron recovery of % and the dephosphorization rate of %, is obtained under the optimum conditions. The final product (metal iron powder) after briquetting can be used as the burden for steelmaking by an electric arc furnace to .

and development aimed at drastic reduction of the concentration of phosphorus present in iron ore. Research [1] has shown that alkalileaching and acidleaching could be used for the dephosphorization of Changde iron ore, which contains an average of % phosphorus. Results of the study indicate that
This paper presents the predictability of phosphorus removal based on simultaneously removed sulphur and massinput of iron ore leached in potassium hydroxide. The reaction vessel containing the solution and ore was heated at a temperature of 600°C for 10minutes.
