METHOD FOR PROVIDING TEMPERATURE CONDITIONS WHEN ORGANIZING THE FOUNDATION OF A LEACHING STACK IN CRYOLITHOZONE CONDITIONS

For the effective implementation of the chemical processes necessary for leaching, it is recommended to maintain the temperature of the stack in the positive region. When laying the base of a stack, volumes of soil with a negative temperature may fall into it. To prevent freezing of the lower horizons of the stack, it is proposed to use chemical reagents containing quicklime. The results of mathematical modeling determined the concentrations of reacting reagents and the dynamics of the temperature field in the base of the stack, ensuring the complete thawing of frozen volumes and the stability of the leaching process in the stack.
