本発明はマンガン団塊に含まれるコバルト、ニッケル、
銅などの有価金属を酸処理により抽出する方法である。[Detailed Description of the Invention] [Technical Field] The present invention relates to cobalt, nickel, and cobalt contained in manganese nodules.
This is a method of extracting valuable metals such as copper through acid treatment.
〔従来技術)

性容器の必要性や塩素の副生による処理が障害となる。[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.
後者は取扱いは比較的簡単ではあるが、有価金属の抽出

などによる高温高圧装置を必要とする。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.
本発明は、簡単な方法により有価金属の抽出率を高める
方法を提供することを目的とする。An object of the present invention is to provide a method for increasing the extraction rate of valuable metals using a simple method.

00 to 200 mesh is preferable, but 20 to 48
Methushi's products are also effective in extracting valuable metals. However, in this case, the extraction speed will decrease somewhat. The amount of carbon material added varies depending on the type of carbon material, but manganese nodules 1

The nickel, copper and cobalt can be separated in the extraction stage.
