Mining processes generate two kinds of waste products: pieces of rock from the mining operations and fine rock materials and perhaps chemicals from the mineral processing operations. Waste rock, foreground, from Diavik Diamond Mine open pits. Top right is the mines processed kimberlite containment area.
Mining waste rock from historic mines or even treated sewage to find useful metals and minerals could be a sustainable way to meet demand for these finite resources.
Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called
#0183;#32;After mining copper metal, involves grinding mined ore to roughly separate copper from waste rock. The copper is concentrated further by slurrying
Mining Waste. Mining wastes include hard rocks, gravels, clays, pebbles, sands, limestones, chalks, siftings of fine fractions, dump tailings of flotation concentration of ferrous and nonferrous metal ores, sulfur ores, apatitenepheline concentrates, coal wastes, halite flotation wastes, screenings of phosphorite, phosphoric ore fines, etc.

Lecture 4: Mining waste SGU Waste RockTailingsMine WaterChemicals Used in ProcessingWaste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks.
Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining for
Constituents of concern for waste rock include sulfurbearing minerals that may generate acid and leach metals contained in the ore body and surrounding rock. (Mining Industry Profile: Copper) Tailings. Tailings are generated during flotation.
Waste Rock Dumps Environmental Notes on Mining, updated September 2009 Waste rock dumps are usually the most visual landforms left after open pit mining. Together with tailings storage facilities, they are also the most prone to erosion. For these reasons, it is essential that careful planning before and
Copper Mining Waste Rock. The disposed waste rock at open pit of Pedra Verde mine still contains high levels of copper even after 30 years of exposure with Cu mainly associated with carbonates oxides and sulphides The process of Cu transference from the waste rocks to the soil has been occurring by chemical weathering and erosion
After the copper is removed, crushed waste rock will be combined with a cement paste meant to keep water from flowing through the tailings. Approximately half of the tailings will be piped back into the mine, while the rest will be buried in a lined pit and capped.
