Studies of the process of solid-phase metallization of pellets and extrusion briquettes (boxes) from the brown limestone ores of the Ayat deposit were carried out. The scheme of manufacturing pellets and braxes under laboratory conditions is presented and described. The results of reduction roasting in a CO atmosphere and in contact with solid carbon at temperatures of 1050 °C and 950 °C for three hours are presented. The mass loss of the metallized samples was measured. The chemical composition of the sites of the initial and recovered samples was studied by the micro-X-ray spectral method on an electron microscope. It was found that at a temperature of 1050 °C, when reduced by carbon monoxide, up to 0.6 at passes into the metal phase. %, and when reduced by solid carbon, the phosphorus content in the metal phase reaches up to 3.1 at.%.
