RECOVERY OF COBALT FROM SLAG |
摘要 |
<p>The process for the recovery of cobalt product from a molten slag having cobalt- and iron-containing constituents, uses a top-submerged lancing injection furnace system. The slag is smelted in a furnace of the system by: (i) charging carbon-containing reductant to the molten slag in the furnace so as to generate a reducing region at or adjacent to a top surface of the slag; and (ii) injecting free-oxygen-containing gas and combustion fuel into the slag by a top-submerged lance of the furnace system to generate a combustion region between the top and a bottom surface of the slag. The process enables control over the iron content of the product, by adjusting the proximity of the combustion region to the slag/metal interface.</p> |
