説明
<p>To enhance Ni recovery from nickel sulfide (NiS), the effects of the metal addition on the Ni leaching using a copper oxidant in acidic solutions were investigated. The use of sodium borohydride (NaBH4) as a reducing agent as the pre-treatment enhanced the initial leaching rate. Additionally, the addition of elemental metals such as iron (Fe0) and tin (Sn0) during the leaching led to a substantial increase in the Ni leaching rate. The added metal reduced Cu2+ to Cu0 in the solution and deposited onto the NiS surface, which then removed nickel disulfide (NiS2), a substance that inhibits the Ni leaching, thereby promoting stable Ni leaching.</p>
