SELECTIVE  DESINTEGRATION  OF  POLYMETALLIC  ORE   REFUSES

Developed for the higher rate of minerals extraction
from polymetallic ore refuses
DRAWBACKS  OF  CONVENTIONAL  TECHNOLOGIES

Conventional technologies of refinement:

roller,  rod  and  ball  mills



> 0,5 mm

  • To 20 % losses of valuable components

  • Energy input to the refinement process to 80 kW·h/t
ELECTRODISCHARGE  REFINEMENT

< 0,1 mm



  Energy input 15 kW·h/t;

  Production rate of one stage to 1 t/h;

  The most complete opening of mineral 
  aggregates followed by formation of component
  free grains for their further separation by flotation
Mechanism of ore-grain release
Recovery growth
after electrodischarge treatment
