poor separation
2.The shape of stainless-steel metal in the swarf is characterized by the morphology of fine strips,which was partly entwined with the granule of grinding wheel,thus lead to the poor separation effect of the magnetic selection.
3.Under the background of our national available iron resource apt to poor、tiny and complex and the price of iron mineral dramatically rise, the separation technology of hematite with high phosphorus which is the most difficult problem in mineral separation area is proposed again.
4.A thought of the introduction of CSV file is presented in the paper because of the poor reuse and adaptability in the database application domain. By means of the design and edit on the CSV file, realizes the distillation and separation of the reusable information and makes the application have the function of adaptability and extensibility, and so realize the dynamic integration with the heterogeneous databases.
