METHOD OF CONTROLLING PROCESS OF SYLVINITE ORE DISSOLUTION Russian patent published in 2015 - IPC B01F1/00 C01D3/08 C05D7/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in the production of potassium chloride. The method of controlling the process of sylvinite ores dissolution includes the regulation of ore supply depending on the content of a useful component in input flows, measurement of the temperature in the input flows, measurement of the temperature of the final solution, determination of sodium chloride by the calculation method, measurement of the density, temperature and dissolving solution consumption, determination of the sodium chloride content by the content of the useful component, density and temperature, calculation of ore supply. In the realisation of the process of sylvinite ore dissolution on two parallel lines with common ore with the total consumption of ore and correction of the ore consumption by the composition of the final solution, additionally measured are: content of potassium chloride and magnesium chloride in the final solution, consumption of ore per one of the lines and the total expenditure of the dissolving solution. Calculated values are supplied as a task into a system for control of a weight dosing device of ore of the general flow and the second line.

EFFECT: invention makes it possible to simplify the process due to the reduction of the number of apparatuses and the amount of control and management means.
