Jarlbring, Mathias and Sandstrom, Dan E and Antzutkin, Oleg N and Holmegren, Allan and Forsling, Willis (2006) The Surface Properties of Aqueous Fluorapatite & Maghemite with Reference to the Dephorization of Magnetite. In: Proceedings of the International Seminar on Mineral Processing Technology and Indo-Korean Workshop on Resource Recycling (MPT-2006), March 8-10, 2006, NML, Chennai.
The Luossavaara-Kirunavaara AB(LKAB) in northern Sweden is one of the biggest suppliers in the world of high grade iron ore products. However, the Kiruna magnetite ore deposit contains an average of 1 wt% phosphorus (mainly fluorapatite), which is detrimental to the blast-furnace technology and the quality of the iron products. Conseque-ntly the apatite content has to be minimized. After magne-tic separation the dephosphorization is performed by froth flotation of the apatite from magnetite fines using a fatty acid type collector (ATRAC)in a combination with sodium silicate. The concentrated magnetite fines are then treated in a pelletizing plant.
