Cobalt sulfates are important intermediates in the extraction of cobalt from its ores. ... Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. For these purposes, the cobalt sulfate is produced by treating cobalt oxide with sulfuric acid.

Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds.

Cobalt oxide or other cobalt derivatives are dissolved in dilute sulfuric acid, which crystallizes to form cobalt sulfate. In addition, large amount of cobalt sulfate is produced as a by-product during the manufacturing of various metals, such as nickel and copper.
