摘要
文章提出对含有明金而脉石硬度低的岩石样品采用加入高硬度的石英砂作为助磨剂,将明金充分粉碎,使制成的金矿样品的均匀性和代表性符合地质样品加工规范要求。通过对部分天然样品及人工合成样品制样测试验证,效果良好。
A processing method for grinding visual grain gold ore with low gangue hardness was developed. In the procedure, the ore samples were completely grinded by using quartz sand as the grinding aids in order to make the uniformity and representativeness of obtained samples meet the demands of geological sample criteria. The method has been applied to treat natural and synthetic samples and satisfactory results were obtained.
