Abstract

Briquetting in ferrous metallurgy is the earliest way clotting. In the beginning of XX century briquetting has been forced out by agglomeration  basically  for  the  reason  considerably more productivity of process of agglomeration. The alternative agglomeration became pelletizing which share from the XX-th century middle steadily grows that is quite explainable essential increase in manufacture fine particle concentrates. However briquetting has a number of advan- tages. And for separate kinds of iron ores briquetting can appear preferable process. Such ores     are the rich iron ores containing 60 and more % iron in ore. The technology of briquetting includes, preliminary screening for removing of large classes; dispensing and preliminary mixing 85-90 % martite, iron-micaceousmartite ores and 10-15 % hydrohematite ores; mixing with connective substances; pressing; drying. The received briquettes have density 3200-3500 kg/m3, durability on compression about 4,5  MPа.
