一長一短がある。Because cobalt and nickel are chemically similar, the separation of cobalt and nickel in ores has long been Q! Met. Conventionally, there are many methods for processing ores containing cobalt and nickel, including recovery using sulfides, oxidative hydrolysis of cobalt using chlorine, separation of nickel by ammonia leaching after reduction roasting, and pressure leaching using an autoclave. However, they all have advantages and disadvantages, such as expensive roasting and corrosion of equipment.
本発明は、コバルト含有鉱石の処理に上記のような特別

鉱石の酸浸出を行う際、炭素材を添加することによりコ
バルトを選択的に抽出するもので次のような特徴がある
。The present invention does not require a special roasting reaction or pressurized reaction equipment as described above for processing cobalt-containing ores, and selectively removes cobalt by adding a carbon material when carrying out acid leaching of cobalt-containing ores. It has the following characteristics:
（１）コバルト含有鉱石からコバルトを選択的に抽出す
る最適条件はＨ２Ｓ０ａ７４度０．０Ｓ〜０．３ ｍｏ
ｆ ｊ！濃度４０〜６０℃、時間３０〜１２０分のとき
にコバルトが溶解中に浸出され、ニッケルは鉱石に残留
し、効果的な分離が行われる。(1) The optimal conditions for selectively extracting cobalt from cobalt-containing ores are H2S0a 74 degrees 0.0S to 0.3 mo
fj! At a concentration of 40-60° C. and a time of 30-120 minutes, the cobalt is leached out during dissolution and the nickel remains in the ore, resulting in effective separation.
（２）使用する炭素材は活性炭、木炭、石炭等いずれも
コバルトの選択的抽出に利用できる。粒度は１００〜２
００メツシユのものが望ましいが、２０〜４８メツシユ

テライト鉱石の場合、Ｌｏｇ当たり０．５〜２ｇ程度が
適当である。(2) Any of the carbon materials used, such as activated carbon, charcoal, and coal, can be used for selective extraction of cobalt. Particle size is 100-2
00 mesh is preferable, but there is no change in the effectiveness of selective extraction of cobalt even with 20 to 48 mesh. However, in this case, the leaching rate will decrease somewhat. The amount of carbon material added varies depending on the type of carbon material, but in the case of laterite ore, about 0.5 to 2 g per log is appropriate.
（３）炭素材を添加しない場合には、常温（２０℃）で
は、コバルト、ニッケルとも浸出されないが、炭素材を
添加するとコバルトだけ浸出される。ニッケルの浸出を
防ぐには酸濃度が低く、低温の場合に効果的であるが、
コバルトの浸出速度も遅くなるため、（１）の反応条件
で浸出することが適当である。(3) When no carbon material is added, neither cobalt nor nickel is leached out at room temperature (20° C.), but when a carbon material is added, only cobalt is leached out. It is effective to prevent leaching of nickel when the acid concentration is low and the temperature is low.
Since the leaching rate of cobalt is also slow, it is appropriate to leaching under the reaction conditions (1).
（４）炭素材添加の場合には、添加しない場合に比較し
て濾過速度が速い。(4) When carbon material is added, the filtration rate is faster than when it is not added.
（５）添加剤が炭素材であり、濾過後の溶液組成には変
化がなく、その後の分離操作には影響がみられない。(5) Since the additive is a carbon material, there is no change in the solution composition after filtration, and there is no effect on the subsequent separation operation.

いてコバルト、ニッケルの分析を行った。The cobalt-containing ore used in the present invention was obtained by adjusting the particle size of Utellite from the Philippines to 100 to 200 mesh, and adding commercially available granular activated carbon, powdered activated carbon, charcoal, etc. as a carbon material. The experimental results are shown in Table 1~
The experimental results shown in Table 4 are not intended to limit the invention. In the experiment, sulfuric acid Loom 1 of a predetermined concentration, laterite ore and carbon material of a predetermined amount were added to a 200 ml Erlenmeyer flask, stirring was performed while maintaining a constant temperature, and after the reaction was completed, the reaction solution was filtered and separated. The filtrate was analyzed for cobalt and nickel.
