The production of iron in a blast furnace requires great quantities of feedstock. Some of the basic raw materials are ore constituents, fuel and other basic additives. Ore feedstock can be bought by steelworks from various sites. The key factor is, naturally, the quality of the ore constituent but also the overall cost of purchase. Production facilities are also forced to consider several sources of supply. The problem in assessing the quality of ores is primarily in the broad range of criteria, which are often categorically different. In order to evaluate ore quality, we can make use of specific criteria or technological indicators. The quantity and range of evaluated parameters offer the use of multicriterial decision-making tools. A broad range of methods and procedures can be applied in this. A great advantage is the quantification of different types of criteria into a single determining parameter. In this research, an analysis of raw ore materials was conducted using multicriterial decision-making management tools. The aim of this paper is to mutually evaluate the quality of three selected types of raw ore material in terms of a wider range of criteria. The comparison will be based on the quantification of selected criteria used by crude iron producers. The comparison and its results can then be used for decision making in the choice of suitable raw ore material, but also for further study of the complex quality of the raw ore material. The research was realized in the environment of a selected iron producer in the Czech Republic.Keywords: ore, criterion, quality, order, rating
