Widely used in agriculture as a fungicide and pesticide, especially in vineyards and farms to control fungal diseases like mildew and blight. It is a key component in the preparation of Bordeaux mixture, which protects plants from various infections. Also used in seed treatment to prevent the spread of fungal pathogens. Commonly applied in the mining industry for froth flotation processes to separate copper and other metal sulfides from ores. Acts as a flotation activator for certain minerals, improving the efficiency of metal recovery. In industrial settings, used in electroplating baths to deposit copper coatings on metals, enhancing conductivity and corrosion resistance. Also utilized in the production of dyes, pigments, and other copper-based chemicals. Employed in water treatment to control algae growth in reservoirs, ponds, and swimming pools due to its algaecidal properties. However, its use is regulated due to toxicity concerns in aquatic environments. Used in educational and research laboratories as a reagent in various chemical tests and demonstrations, such as crystal growth experiments and electrochemical studies. Also applied in the preservation of wood and textiles in some specialized treatments.
