Fundamentals of technology for producing copper nitrate from copper waste

Purpose:

To provide a product with a high copper nitrate content for future use.

Area:

Recycling of non-ferrous metal waste; chemical, light and other industries and agriculture.

Advantages:

Application of uncomplicated serial equipment; resource and energy saving; the possibility of using the solution as a liquid nitrogen fertilizer; low cost of the product.

Description:

They are based on dissolving prepared copper shavings in nitrate acid, followed by evaporation and cooling of the solution and separation of Cu (NO3) 2 · 3H2O. The resulting product contains at least 98.3 and 98.7% Cu (NO3) 2. It can be used to obtain copper-containing catalysts, high-purity CuO, as a fungicide, for etching fabrics before painting, for bronzing, for the manufacture of mineral paints, enamels, etc.
