Copper sulphate can be used to kill fungi. It is mixed with lime water to form Bordeaux mixture. It is used as a fungicide to control fungi on crops such as lemon and grape, and to prevent fruit from decaying. Dilute solutions are used for sterilization in aquariums and for removing snails. Since copper ions are toxic to fish, the amount must be strictly controlled. Most fungi can be killed with very low concentrations of copper sulfate, and E. coli can also be controlled. In addition, the aquaculture industry is also used as the main raw material for trace element copper in feed additives.

• It is an important trace element in drug feed.
• Added into diet, it can effectively prevent and treat anemia, weak limbs, bone growth, joint swelling, osteoporosis, growth retardation, heart failure, gastrointestinal diseases and other symptoms.
• Promote the growth of livestock and aquatic animals, enhance disease resistance, improve feed utilization.
• Sheep can also improve wool production and improve the quality.
• Pigs also have similar antibiotic effects.

Copper sulphate is the electrolyte when electrolytic refined copper. After several purification and filtration processes, electroplating grade copper sulfate can reach high purity. It will gradually lose crystal water when placed in the air for a long time and change into white.
