Major Mines Projects

The Henderson mine is a porphyry molybdenum deposit with molybdenite as the primary sulfide mineral Mining Methods Block caving Source: The mine and the Mill are connected by a fifteen-mile elevated belt that passes underneath the Continental Divide through an old train tunnel and then above ground to the mill

Major Mines Projects

Mill 6 processed approximately 3 4 million tons of ore in 2016 Higher-grade surface oxide ores are processed by conventional milling and cyanide leaching at Mill 5 Additionally Mill 5 operates as a flotation mill treating lower grade non-carbonaceous sulfidic refractory ore to produce a

NRC: Conventional Uranium Mills

Mill tailings are typically created in slurry form during processing and are then deposited in an impoundment or mill tailings pile which must be carefully regulated monitored and controlled This is because the mill tailings contain the heavy metal ore constituents as well as a residual amount of radium which is produced during the radioactive decay of uranium

Present Mining Methods and Possible Developments

The underground coal mining industry in Australia has in the last 30 years undergone a revolution in production methods techniques and results probably unparalleled elsewhere in the world It can lay claim not only to leading the fight against pneumoconiosis and setting high safety standards generally but has at the same time recorded comparatively high

Types of Mine Waste and Disposal Methods

Due to the many variables mining operations will need to develop their own methods of waste disposal in accordance with regulations pertaining to different types of waste they produce However it is worth noting that a large portion of mining waste is benign to the environment and is routinely used to revegetate or contour the land when the mining operation has been completed
