primary explosives can be easily detonated . due to their extreme sensitivity to heat, friction, impact, static electricity. mercury fulminate, lead azide or petn (or penthrite, or more properly penta erythritol tetra nitrate) are good examples of primary explosives used in the mining industry. they can be found in blasting caps and detonators.,mine tailings - groundtruthtrekking.org,mine tailings' size and composition depends on the mining method. for hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. tailings may also contain chemicals used for mineral extraction.
