FIELD: chemistry. ^ SUBSTANCE: invention can be used in production of synthetic carnallite. Proposed method comprises adjusting ore feed depending upon the content of useful component in inlet flows and measurement of temperature. Besides solvent flow rate, solvent density and content of magnesium chloride therein and content of potassium chloride in carnallite ore flow are measured. Parametres thus obtained allow determining carnallite ore flow rate from the relationship indicated below to make setting to be incorporated with ore consumption control system: where Gore is the consumption of carnallite ore, t; Gsol is the consumption of solvent, t; is the content of potassium chloride in carnallite ore, %; is the content of free potassium chloride not bound in carnallite, %; is the content of magnesium chloride in saturated solution set by enterprise operating conditions to make 28.50.5%; is the content of magnesium chloride in solvent, %. ^ EFFECT: simplified dissolution of carnallite ore. ^ 2 cl, 2 tbl, 2 ex |
