Abstract:
An assemblage of granules including zinc sulfate heptahydrate and iron sulfate heptahydrate in a substantially integrated granular form is provided for use in e. g. , the fertilizer industry. A binder, such as humate, may be used to form the granules. The granules may be dried until a slight melt is formed thereon. The granules may then be cooled to remove remaining free water. Related methods provide additional advantages.
