A method in recovering nickel and possibly cobalt through leaching from inckel-containing laterite ore. Crushed and possibly pre- ground nickel-containing laterite ore is ground in an attritor mill into a size which is suitable for leaching. Then laterite ore in an attritor mill can be leached with leaching liquid , e.g. sulphuric acid, hydrochloric acid, or sulphuric acid + SO2, at relatively low temperatures. Nickel and possibly cobalt are recovered from the leaching solution. |
