Abstract

PURPOSE:To extract the valuable metals such as Co, Ni, and Cu from an Mn nodule with a simple method, by adding a reducing agent such as a carbonaceous material or the carbonaceous material and hydrazine to the nodule, and leaching out the metals with an acid. CONSTITUTION:The Mn nodule preferably controlled to about 100-200 mesh is added with the reducing agent such as the carbonaceous material of charcoal, etc., or the carbonaceous material and hydrazine or a hydroxylamine-based reducing agent also controlled to the same grain size range. The Mn nodule added with the additives is subjected to extraction, and the valuable metals such as Co, Ni, and Cu are efficiently extracted. About 0.5-2g of the carbonaceous material is appropriately added per 10g/l Mn nodule. Besides, hydrazine hydrate, hydrazine sulfate, etc., are preferably used as the hydrazine component in the reducing agent, and hydroxylamine sulfate, etc., are used as the hydroxylamine component.

[Prior Art] Several methods have already been proposed for smelting manganese nodules, including the smelting-leaching method, the roasting-leaching method, and the direct leaching method. The smelting-leaching method includes a process of melting manganese nodules at a high temperature of 1300°C to 1400°C.
The roasting-leaching method, which consumes a large amount of energy, also involves leaching through roasting processes such as reduction roasting, sulfation roasting, and chloride roasting, but each has advantages and disadvantages in terms of selectivity. Direct leaching methods include treatment with hydrochloric acid or sulfuric acid, but the former is hampered by the need for corrosion-resistant containers and by-products of chlorine.

Although the latter is relatively easy to handle, increasing the extraction rate of valuable metals requires either increasing the sulfuric acid concentration or using a high-temperature, high-pressure device such as an autoclave.
