REDUCTION SMELTING METHOD IN A SHAFT FURNACE WITH RECOVERY OF VOLATILE SECONDARY METALS |
| 摘要 |
<p>A method for reducing metal oxides in a shaft furnace. A charge of metal oxide and a reductant is reacted in the furnace to produce a primary metal of the metal oxide and an additional secondary metal. The temperature of the off gas from the reaction is controlled to prevent condensing of the secondary metal so that it remains in the off gas for separation therefrom.</p> |
