Abstract: The proposed solution to the problem of safety of salt - a new approach to the purification of concentrated solutions of salt (? 280 g/l) from impurities of toxic elements: arsenic, cadmium and copper. It was established experimentally that when cleaning concentrated solutions of sodium chloride ? 280 g / l, using as a collector a mixture of magnesium hydroxide and calcium carbonate, with an amount of magnesium hydroxide not less than 4 mmol / l, and calcium hydroxide 1 -2 mmol/l with the intensification effect ultrasound with a frequency of 18–53 kHz, an intensity of 1.0– 2.5 W / cm2 and ultrasound with a frequency of 2–4 MHz with an intensity of 0.75–1.25 W / cm2 for 30–45 s allows an increase in the degree of purification of concentrated solutions of sodium chloride from 12-33% to 90-97%.
