Investigation of physico-chemical characteristics of iron-containing technogenic raw materials in the conditions of JSC “AMT”

The results of experiments conducted to determine the efficiency of the use of man-made waste, including largescale in volume among the waste of metallurgical production, melted films and sludge of the oxygen converter shop are presented. During the study of the sludge of the converter shop, the chemical, phase, granulometric composition and density of rolling scale and sludge of the oxygen converter shop were revealed

Thermodynamic interaction of concentrate, sludge and mill scale from carbon

Due to the gradual depletion of reserves of a number of natural minerals, on the one hand, and the accumulation of a huge amount of waste containing valuable useful components, on the other, the problem of developing so-called man-made deposits is becoming increasingly urgent. Of particular interest are currently man-made deposits formed or being formed on the territory of the objects of placement of man-made waste of the metallurgical complex, including the preparation of raw materials (mining, processing, agglomeration, etc.), directly metallurgical processing and related production. The downward trend in iron ore reserves makes it particularly relevant to process manmade waste from ferrous metallurgy in order to obtain man-made iron ore raw materials

Complete thermodynamic analysis of the interaction of iron phosphate (FePO4) with hydrogen (H2) and carbon monoxide (CO)

Iron phosphate in the composition of concentrate is a fairly strong chemical compound. However, with the help of gaseous substances, such complex compounds decompose when heated to the required temperature, which contributes to the reduction of not only iron, but also phosphorus. Hydrogen and carbon monoxide were used as gaseous reducing agents. This article describes in detail the thermodynamic analysis of the reduction of phosphorus from iron phosphate, its interaction with hydrogen and carbon monoxide
