基于浮选工艺改进与图像处理的铜矿筛选研究

A Research on Copper Ore Screening on Flotation Process Improvement and Image Processing

为提高铜矿筛选工艺的效率和筛选精度,结合铜矿筛选问题,从筛选工艺和筛选图像处理的角度对铜矿筛选进行研究。一方面结合铜矿石的物相分析和传统的混合筛选工艺,提出一种优选浮选硫化铜—氧化铜改进工艺;另一方面,针对在浮选中人工筛选存在的弊端,借助现代图像处理技术筛选出Cu2S和Cu O矿石。最后通过试验对样品进行筛选,结果表明最终铜的回收率可达到91.96%的标准,验证了两者方法结合的有效性。

In view of many minerals in traditional iron ore,we know how to select the copper sulfide ore in the mineral ore efficiently to improve the efficiency of the ore screening,as has become the focus of the current thinking and research. To improve the screening accuracy of copper ore,the screening of copper ore was studied on point of view of screening process and screening image processing. After a combination of copper ore phase analysis and conventional hybrid screening technology,we have put forward an optimum flotation of copper sulfide and copper oxide process improvement. On the other hand,we are aiming at the drawbacks of existing in the flotation of artificial selection with the help of modern image processing technology to screen the Cu2 S and Cu O ore. Through the above screening,we have got final recovery rate of copper with 91. 96% standard,which has verified the effectiveness of the combination.
