. The object of works has been the barite-bearing technogenic wastes. The wastes include the final tailings of the Karagailinsky mining and processing plant. They are stored in the tailing dumps, and they have been formed during the flotation concentration of the barite-polymetallic ores of the Karagaily deposit [1-2]. These tailing dumps occupy a huge territory. Thus, the dumps are pollution sources of soil, air and water by the heavy metals and barite dust. These wastes have been not recycled yet, i.e. there is no effective technology that would allow the cost-effective production of the quality commercial products. The issue with the barite-bearing waste recycling is its complex mineralogical composition. Thus, it leads to the inefficiency of the traditional recycling methods such as the acid leaching and flotation [3-5]. In order to solve these issues on this raw materialrecycling, some methods should be found to explore the ore mineral aggregateswith the silicon-bearing gangue minerals [6-7]. A promising solution to the issueis to explore the raw materials with the chemical methods, in particular, by a method of ammonium fluorosulfate desiliconization. Studies have been performed to explore the barite raw material by the sintering with ammonium fluorosulfate. As a result, a mathematical model of the exploration has been created and the optimal conditions for this process have been determined. The partial dependences of the raw material exploration on temperature, sintering time and consumption of the exploring reagents have been obtained. Based on the partial dependencies, a mathematical model of the sintering as a generalized multifactor equation has been created. This equation has determined the optimal conditions to explore the barite raw materials. A scheme of ammonium fluorine sulfate exploration of the barite raw materials has been developed
