Widely used in agriculture as a fungicide and soil additive to correct copper deficiency in crops. It helps control fungal diseases in plants and is a key component in Bordeaux mixture, a traditional spray for vineyards and orchards. Commonly used in industrial settings for electroplating processes, where it serves as a source of copper ions in plating baths to coat surfaces with a thin layer of copper for conductivity or corrosion resistance. Employed in mining and metallurgy for the extraction and purification of metals, particularly in solvent extraction and electrowinning operations. Used in educational and research laboratories as a reagent in various chemical tests and experiments, including crystal growth and redox reactions. Found in some wood preservatives and algicides for controlling algae in ponds, reservoirs, and swimming pools. Utilized in the textile industry for dyeing processes and as a mordant to help fix dyes to fabrics. Also applied in the formulation of animal feed supplements in controlled amounts to ensure adequate copper intake in livestock.
