Recently, a unique technology for processing iron ore raw materials containing harmful phosphorus impurities was tested on a semi-industrial scale in the sintering plant of Qarmet JSC.
According to the Zh. Abishev Chemical and Metallurgical Institute, a branch of the RSE "National Center for Integrated Processing of Mineral Raw Materials of the Republic of Kazakhstan", brown iron ore was very limited in its use until recently due to harmful phosphorous impurities. And for the first time in the world, scientists at the Institute have developed and successfully tested a method for processing brown iron ore together with specialists from Orken LLP.
According to the RSE press service, the resulting concentrate meets the requirements for iron ore raw materials for the ferrous metallurgy (iron – 60.81%, phosphorus – 0.3%, silicon oxide – 7.59%, aluminum oxide – 3.61%).The technology has no analogues in the world and can be adapted for the enrichment of identical phosphorous brown iron ore produced at the largest Kazakh and foreign deposits.
