Abstract

The methods of scanning electron microscopy, potentiometric titration (electrode potential), and microhardness measurements are used to study the mechanism of the influence of electromagnetic-pulse impacts of two types (dielectric-barrier discharge in air at atmospheric pressure and high-voltage nanosecond electromagnetic pulses) on the morphology, structural and physical-chemical properties of the surface of natural pyrrhotite and chalcopyrite. The advantages of the use of short-term (t_treat = 10–30 s) energy impacts for structural and chemical modification of the surface and physical-chemical properties of sulfide minerals of iron and copper in order to improve the efficiency of treatment of difficult copper-nickel sulfide ores are shown.

介质阻挡放电对磁黄铁矿和黄铜矿表面形貌和理化性质影响的研究

摘要

采用扫描电镜、电位滴定（电极电位）和显微硬度测量等方法，研究了两种电磁脉冲冲击（常压空气介质阻挡放电和高压纳秒电磁脉冲）的影响机理。脉冲）对天然磁黄铁矿和黄铜矿表面的形态、结构和物理化学性质的研究。使用短期（t_处理= 10-30 秒）能量影响对铁和铜硫化物矿物的表面和物理化学性质进行结构和化学改性的优势，以提高处理难处理的效率图中显示了硫化铜镍矿石。
