 2018-02-09 For the first time in Georgia, there were studied the possibilities of obtaining potassium compounds and slow-release biofertilizers from trachytes - mantle rocks of Askana bentonite clays. It was established that investigated samples belong to potassium feldspar. For creating microorganism bank, active strains of silicate bacteria were isolated from trachytes; the optimal parameters of the bacterial leaching process of trachytes were determined; dissociation kinetics of raw material and possibilities of activating the leaching process by using various additives were studied; for comparative analysis, the existing and new chemical directions for preparation of potassium compounds from trachytes were studied; it was established, that mechanical leaching is more effective than alkaline leaching process; the filtration regime of the suspension obtained by leaching of trachytes and facilitating conditions for maximum transition of potassium oxide were studied; it was established possibility of using sorbent zeolite for extraction of potassium oxide, passed into solution in result of trachyte leaching; for the first time in Georgia, there was produced slow-release potassium biofertilizer by treatment of potassium sorbate mass using silicate bacteria; examine of obtained product in open and protected ground conditions revealed the efficiency of the produced fertilizer; based on the comparative analysis it was established that biotechnological method of tachyte processing was characterized by significantly high features, than chemical method; availability of soda-potash product from suspension obtained by microbiological leaching of trachytes was established; it was determined, that using waste (cake) as additive in manufacturing of cement increased its strength. Continuous, non-waste technological scheme for trachytes bacterial processing was developed.
Elaboration of non-waste technological scheme for fabrication of deficient potassium compounds for industry and agriculture from natural and technogenic waste of Georgian trachyte, has a great importance for development of both industry and agriculture, because this technology is economic and environmentally-friendly. Soda and potash fabricated by this technology are deficient and necessary products for industry development, whereas using of slow-release potash biofertilizer for cops at vegetation period increases their productivity.
