Abstract
A study of the physicochemical characteristics of mill scale and dehydrated sludge from gas purification of oxygen-converter production was made. Their chemical, phase, particle size distribution and density are determined. It was established that the total iron content in the scale is 73.3%, in the sludge – 41.2%. The technological expediency of their use in metallization processes is determined. In this case, preliminary briquetting in a mixture with a carbon reducing agent is necessary.
