Abstract

Iron ores is one of the main types of minerals used used by mankind. Practically all domestic deposits contain 20-40 % iron ore and so are the deep concentration. Deposits of rich iron ores, containing more than 55-60 % in our country is not enough. One of these fields is Yakovlevskoye iron ore deposit. The use of dry magnetic separation of ore for the preliminary concentration did not give positive results. The study of grain-size composition  of  the  ore  showed a significant disparity in the distribution of iron by classes size that afford it possible to carry out preliminary concentration of ore screening. For ore processing flowsheet is proposed which includes crushing to a particle size of 10 mm, screening fraction of 5 mm. Larger fraction  of 5 mm is used, for example, in the blast-furnace process, and the fraction smaller than 5 mm is direct to the briquetting. As binding substance for briquetting used solution of carboxymethyl cellulose, or a combination of binder based on carboxymethyl cellulose or highly active   clay.
