PURPOSE:To make metallic manganese soluble and to recover it by a wet process by immersing a mineral contg. manganese dioxide such as manganese dioxide ore, manganese nodules or electrolytic manganese dioxide in an acid in the presence of a carbohydrate such as a saccharide or starch to leach out manganese from the mineral. CONSTITUTION:When a mineral contg. manganese dioxide such as manganese dioxide ore, manganese nodules or electrolytic manganese dioxide is immersed in an acid such as sulfuric acid to leach out manganese from the mineral, a carbohydrate such as a saccharide or starch is added. The carbohydrate acts as a very effective auxiliary for dissolving a useful metal such as manganese, so the metal is made soluble at a low temp. and recovered very effectively by a wet process at a reduced cost.
