The Cobalt sulphate heptahydrate can be produced by reacting the raw materials containing cobalt such as metal cobalt, cobalt oxide, cobalt trioxide, cobalt furnace slag with mixed acid such as sulfuric acid and nitric acid after the process of concentration, crystallization, separation and purification. The cobalt sulphate monohydrate can be prepared by cobalt sulphate heptahydrate after heating and dehydrating.


In feed industry, it is a nutritional fortifier to supply cobalt element, which can be used to prevent and treat animal anemia, improve blood volume and the ability of blood to transport oxygen. And besides, it has a good preventive effect on animal's appetite decline, severe weight loss, diarrhea, reduction of milk production and breeding ability, and calf death.
