FIELD: chemistry. ^ SUBSTANCE: invention relates to technique of controlling processes of sylvinite ores dissolution and can be used in production of potassium chloride by dissolution-crystallisation method. Method of controlling processes of sylvinite ores dissolution includes regulation of ore supply depending on content of useful component in input flows, measuring ready solution temperature and determining sodium chloride content in solution by calculation method. Additionally determined are density, temperature and consumption of dissolving solution, content of sodium chloride in it is determined by content of useful component, density and temperature. Ore supply is calculated according to suggested equation and calculated value is given as task to system of weigher control. ^ EFFECT: invention allows to simplify controlling process of sylvinite ores dissolution. ^ 2 cl, 8 tbl, 3 ex |
