WebElectrical current within a rock will choose not to flow through the pore-space if the rock forming minerals are more conductive. This occurs frequently in ore-bearing rocks due to the presence of metal-oxides (magnetite, illmenite, specular hematite), metal-sulphides (pyrite, pyrrhotite, galena) and native metals (gold, silver, copper). Webconductive pressure sensitive adhesive (CPSA) tapes and electrically conductive films provide excellent adhesion to a variety of substrates including metals and plastics. These tapes and films are easy to apply and can be hand or machine applied and die-cut, thus enhancing productivity.
