First, the Sunburn Astragalus, Guizhi, peony, Zhigancao into filter paper bag, put the pot of water to join Siwan, small heat and simmer 30 minutes, then put to fine cut onion, ginger ground into juice, mixed with the meat dumplings, plus pepper, wine, sesame oil, salt and accompanied to the sticky, take appropriate amount to dumplings.

首先，炙黄芪，桂枝，芍药，到炙滤纸袋，把一锅水加入汐，小火煮30分钟，然后付诸细切葱，姜磨成汁，与肉圆混合，加辣椒，酒，麻油，盐和陪同下，前往粘，采取适当的数额饺子。

Due to the finer size and little dense difference between Perovskite and Titanaugite, shaking table was employed as the main equipment of gravity separation. The ground products were screened four classifications. Some qualified tailings could be cast away in the coarser fractions, which could decrease disposal quantity of the next step-floatation.

对实际改性渣进行了选择性分离，基于相对较细的粒度和二者密度相差较小的事实，选择摇床为重选设备，并采用分级入选的方式，在较粗级别可抛弃部分合格尾矿，减少磨矿和下一步重选或浮选作业的处理量。
