A kind of preparation method of granular xanthate

Abstract

The invention discloses a preparation method for granular xanthate. The preparation method comprises the following steps of adding 0.05%-5% of additives in a xanthate synthesis process by using a solvent method; distilling a recovered solvent after reaction is finished; and granulating the xanthate to obtain the granular xanthate. The additives comprise one or more of alcohol perfume, phenol perfume, ketone perfume, ether perfume and ester perfume, pungent odor of the xanthate can be eliminated by using the additives, and a flotation effect is improved. By using the preparation method for the granular xanthate, the work environment of the xanthate in producing and using processes can be effectively improved, and industrial production is realized easily.

Description

technical field

[0001] The invention belongs to the field of preparation of flotation collectors, in particular to a process for preparing granular xanthate. Background technique

[0002] Xanthate, namely xanthate ROCSSNa (K), is currently the most widely used and consumed flotation collector in the mineral processing field.

[0003] At present, most of the xanthates used in production are powdery xanthates. The powdery xanthates have a lot of dust pollution during preparation and use, serious waste of spilling, inconvenient use, and the stimulation of powdery xanthates. The strong odor is very strong, causing serious pollution to the environment of xanthate production plants and mineral processing plants. The domestic process of preparing granular xanthate is mainly to extrude the powdered xanthate directly synthesized by the kneader through a granulator, or add a certain amount of binder to extrude and then dry it. The binder currently reported is mainly water. Glass (Xu...
