甲玛铜铅锌多金属依次优先浮选工艺优化试验研究
Gansu Metallurgy(2021)
Abstract
西藏甲玛乡铜铅锌多金属硫化矿含铜1.08%、铅0.84%、锌0.49%.为综合回收各有用矿物,选矿厂采用铜铅锌依次优先浮选工艺流程.实际生产铜精矿中铜品位为15.77%,铅+锌品位为19.84%,铜精矿铜铅锌品位均不理想,此次指标优化试验研究重点在于提升铜精矿中铜品位,降低铅锌品位.通过多种探索性试验获得铜精矿中铜31.52%,铅+锌5.78%,铜回收率90.67%的良好技术指标.由此,对于复杂类型及特殊地理位置矿石选矿试验提供一个范例.

Key content
- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
