FIELD: crystal growing.
SUBSTANCE: method comprises using inner and outer systems of circulations. The inner system of circulation is mounted inside the crystallizer provided with the classification zone that receives the crystals of material. The classification zone is made of a sedimentation zone. The portion of the dispersion outflowing from the crystallizer is directed to the outer circulation system through the classification zone. The crystals are dissolved in the outer circulation system by means of the device for dissolving crystals. The dispersion or solution is directed back to the inner circulation system. A portion of the dispersion flow is withdrawn from the inner circulation system and introduced into the outer circulation system, and/or a portion of the dispersion flow is withdrawn from the inner circulation system and then is introduced again in the inner circulation system.
EFFECT: enhanced quality of crystals.
