FIELD: preparation of iron ore.
SUBSTANCE: invention can be used in production of sinter for metallurgical processing. The furnace charge includes iron ore material, limestone, solid fuel and a binder in the form of an organic surfactant - an aqueous solution of ethoxylated alkylphenol. The mass ratio of ingredients in the charge is as follows, in % by weight: limestone 5-10, solid fuel 5-10, ethoxylated alkylphenol 0.06·10-5-0.07·10-5, the rest is iron ore material.
EFFECT: obtaining high-quality sinter, increasing yield and reducing fuel consumption.
