Introduction. The objective of the research is to study the effect of the complex activation of the alumina raw material on the rheological properties of the ceramic mass. In addition, the authors investigate solutions for the application of optimal coagulation structures based on loams and ash together with plastic certificates.Materials and methods. The authors used the local forest like reserves of clay loams at the BashKarasu, ash fields of the Bishkek Central Heating Centre (BTEC) and plasticizer (sodium naphthenate obtained from alkaline chemical production wastes) as fibrous materials. Moreover, the authors defined technological properties of raw materials within standard laboratory methodology in accordance with current GOSTs.Results. The researchers tested plastic durability on variously prepared masses for the choice of optimal structures. The paper demonstrated the plastic durability of complexly activated compounds comparing with non-activated and mechanically activated compounds. The sensitivity coefficient increased the amount of clay loams by mechanically and complexly activated, which predetermined the possibility of intensifying the process of drying samples based on complexly activated masses.Discussion and conclusions. However, mechanical activation of clay material reduces the period of relaxation and increases the elasticity coefficient of ceramic masses by 1.8–3.4 times, meanwhile decreases elasticity, viscosity and the conventional power during molding, which generally worsens the molding properties of the masses. Сomplex activation of ash-clay material decreases the period of relaxation and provides an increase in elasticity, plasticity of ceramic masses by 46–47%, reduction in viscosity by 1.5–2 times, conventional power on molding by 37–122% in comparison with MA clay loams. Ceramic masses based on spacecraft alumina raw materials belong to the SMT with improved rheological properties; products based on them pass through the mouthpiece for 5–7 seconds.

Introduction. The article deals with the aspects of the use of Medical Clays in Pharmaceutical Technology. A review of the traditional areas of application of Medical Clay, as well as highlighting new directions.Text. One of the main problems of domestic industrial pharmacy is a narrow nomenclature of active pharmaceutical substances and excipients. Replenishment of the nomenclature occurs in two ways-through the synthesis of new chemical compounds or through the processing of natural raw materials of animal, plant or mineral origin. In the process of purification and processing of mineral raw materials, Medical Clays are obtained, which are now widely used as active pharmaceutical substances for the production of Enterosorbents, as well as auxiliary substances.Conclusion. A review of perspectives and areas of use of Medicinal Clays have shown that at present, Medical Clays used in the three traditional areas: cutaneous application, application per os, application in pharmaceutical and food technology. A promising direction is the use of Medical Clays as transport drug systems. The study of this information array and its generalization has undoubted practical and scientific significance in modern pharmaceutical technology.

Technogenic Raw Materials

Innovative processes of deep and complex processing of technogenic raw materials in the context of sustainable development of the mining industry and the economic challenges facing the mining industry should ensure the transition to a circular economy and the maximum use of natural resources. The article reflects the priority scientific and technological research on the involvement of technogenic mineral resources in efficient processing. Presented, developed at ICEMR RAS, including jointly with universities, research and production organizations and enterprises, modern innovative processes of deep and environmentally friendly processing of refractory mineral raw materials of complex material composition (tailings of enrichment of non-ferrous and noble metal ores, poor off-balance ores, slags ferrous and nonferrous metallurgy, sludge of metallurgical production) and hydro-mineral technogenic resources (acidic mineralized bottom-dump waters of mining enterprises of the copper-zinc complex of the Urals, saponite-containing circulating waters of diamond processing factories). Among other things, new directions in the field of selective disintegration of finely dispersed mineral raw materials based on energy effects and deep processing of slags are outlined; increasing the selectivity of enrichment processes; combined processing of technogenic raw materials; resource-saving processing of technogenic and hydro-mineral resources, obtaining secondary products from processing waste. It is shown that in the face of new economic challenges, Russia has sufficient scientific and technological potential in the field of deep and environmentally safe processing of technogenic raw materials in the form of developed and, to varying degrees, tested innovative resource-saving technologies that correspond to the world level, and in a number of technologies are superior to it.
