研究了采用回转短窑对硫铁矿烧渣进行焙烧以回收有价金属的方法 ,考察了不同的工艺条件对硫铁矿烧渣焙烧的影响.研究结果表明 :在还原温度在1 250℃下、还原时间为60 min下 ,硫铁矿烧渣得到充分的还原.金、银、铜、铅、锌的挥发率中试分别达到93 .26% , 82 .20% ,82 .55% ,88 .53% 和83 .48% ,此时球团的硬度可以达到2 100 N.
研究瞭採用迴轉短窯對硫鐵礦燒渣進行焙燒以迴收有價金屬的方法 ,攷察瞭不同的工藝條件對硫鐵礦燒渣焙燒的影響.研究結果錶明 :在還原溫度在1 250℃下、還原時間為60 min下 ,硫鐵礦燒渣得到充分的還原.金、銀、銅、鉛、鋅的揮髮率中試分彆達到93 .26% , 82 .20% ,82 .55% ,88 .53% 和83 .48% ,此時毬糰的硬度可以達到2 100 N.

The roasting method was used to recover valuable metals from pyrites cinder in rotary kiln , and the influences of different process conditions on roasting pyrite cinder were examined . The results show that the pyrite cinder can be fully reduced under the conditions of reaction temperature at 400℃ and reac-tion time for 60 minutes . The volatilizing rates of gold , silver , copper , lead and zinc in pilot scale experi-ment can reach 93 .26% ,82 .20% ,82 .55% ,88 .53% and 83 .48% , respectively . Hardness of the pellets can reach 2100 N at this time .
