Main uses:

Salicylic hydroxamic acid can form stable chelates with tin, tungsten, rare earth, copper, iron and other metals, but unstable chelates with alkali earth metals and alkali metals, so salicylic hydroxamic acid has good selectivity. Especially, when salicylic hydroxamic acid chelates with cassiterite, it can not only form a variety of outer complex salts, but also form different inner complex salts. Therefore, salicylic hydroxamic acid has a strong selectivity to tin. The product is usually used in combination with P86 in cassiterite processing, and has certain foaming property. The product also has the characteristics of low toxicity (it is 1/16 of bienylarsonic acid, so the application of this product can also greatly improve the environmental protection problem), low dosage, strong applicability and so on, and has a higher value of promotion and application.

Storage and transportation: waterproof, insolation, fire protection.
