  • Ore Dressing Methods

    Gold Ore ProcessingMethods of Ore TreatmentAmalgamationConcentrationCyanidationGold-Milling DataThe fact that a product of high value and small bulk can be produced at a gold mine, often by relatively simple milling processes, has made it possible to operate gold mines successfully in remote and inhospitable regions where high costs of transportation, fuel, and power would make it impossible to exploit profitably base-metal ores of equal dollar value. As a result, in many instances gold-mine development has been the advance guard of civilization in regions where other mineral resources were

  • Tunnels and underground excavations Tunneling techniques

    Tunnels and underground excavations Tunnels and underground excavations Tunneling techniques: Tunnels are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous. While these four broad types of ground condition require

    Causes of Tunneling WoundsAssessment and Management of Tunneling WoundsGoals in The Treatment of Tunneling WoundsGenerally, the cause of the tunneling needs to be determined in order to treat the wound. Therefore, the first job of the health care professional is to assess the reason for the tunneling. There are many different reasons for tunneling wounds: 1. Infection that has caused the destruction of tissue. 2. Shear and pressure on a wound which concentrates on the tissue layers and causes separation and tunneling. 3.
