The reason that HA granules bring positive charge in absolute alcohol may be related tosurface absorption or association reaction with 〓; EPD includes two process, that iselectrophoresis and deposition, wanting to make EPD go with a swing, a critical voltagevalue Vc between two electrodes must be reached. The edge effect affecting EPD can beweakened through introducing pulse direct-current main.

HA颗粒在无水乙醇中带正电的原因可能与其表面吸附或缔合〓有关；EPD包括电泳和沉积两个过程，要使EPD能顺利进行，两极间电压必须达到一临界值Vc；采用脉冲直流电源可削弱边缘效应对沉积的影响。

这种差异与配位吸附树脂上的金属离子络合有水分子及介质与树脂间的作用强弱有关。

Brief description is given to the test on the technology for comprehensively recovering gold and silver from tellurium-bearing slag: Tellurium-bearing slag is ground and leached with water to produce crud tellurium dioxide which is then purified through ion precipitation and complexing purification process; leaching reside is leached with chloride to produce copper and bismuth, bismuth oxychloride is recovered through neutralization and hydrolysis and sponge copper is recovered through cementation; gold and silver in the remaining residue can be recycled to the gold and silver smelting system for recovery.
