is zinc a extraction or an mining technique

gold extraction / mining gold info

subsequently the gold is filtered out of the leach solution by adding zinc dust then washed out of the muddy substrate and finally dried the recovered raw gold is later refined into fine gold major reservations exist against this method of extraction due to the release of highly poisonous easily flammable hydrogen cyanide
