6) carbonaceous lead zinc ore
含碳铅锌多金属矿石
1.
The carbonaceous lead zinc ore in Inner Mongolia is very large in reserve,but it contains a high level carbon,which interferes with the selective flotation of these ores,making the selective process target very low and economic benefit poor.
内蒙古含碳铅锌多金属矿石储量大 ,含碳量高 ,矿石性质复杂 在碳的干扰下 ,造成铅锌多金属矿选别工艺复杂 ,选别指标低 ,经济效益差 通过近几年的实验研究 ,含碳铅锌多金属矿石的除碳工艺有了很大改进 ,使选矿指标有了很大提高 ,为开发利用含碳铅锌多金属矿石提供了可靠的技术工艺资
