Study of Mineral Extraction by Various Geotechnological Methods

In recent years, deposits and manifestations of various genetic types (copper-porphyry, coppercoalch, copper sandstone, etc.) have been discovered in the territory of the Nakhchivan AutonomousRepublic (Diakhchay, Yalinlig, Goydag, Goygol, Nasirvaz, etc.). However, in most of these fields, thediscovered reserves and forecast resources were considered out of balance for exploitation byconventional methods. Experiments show that the development of this type of copper deposits by thegeotechnological - underground mining method gives economically efficient results. In the article, it isrecommended to process these deposits by the etching method. Reagents are offered to perform etching.The technical economic indicators obtained during wear are interpreted.
