Opening of Sulfide Gold-Bearing Ores using Nanosecond Electromagnetic Pulses in Aqueous Medium

  • Published:
Metallurgist Aims and scope

This article demonstrates that the yields of gold, silver, and copper increase when sulfide gold-bearing ore is exposed to nanosecond electromagnetic pulses (NEMP) in an aqueous medium. The pulse generator was operated under a duration of 1 ns, pulse rise front of 0.1 ns, amplitude of 15 kV, repetition rate of 1 kHz, and pulse power of 4.5 MW to study the impact of NEMP on ore extraction. The research objects were sulfide ores obtained from the open pit of Bashkir Gold Mining Company. Results revealed the possibility of using the proposed method to prepare gold-bearing ores for cyanidation to increase their output of precious and non-ferrous metals.
