Second, Olimpiada's Vostochny pit has reserves of high-content antimony ore and the mineralogical properties in the pit suggest the deeper horizons having an increased amount of this material. Even in 2016-2017 a conservative estimate for the high antimony ore mined at Olimpiada is estimated at 11 Mt.

Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

After multi scheme of test, HOT mining finally decided to use gravity separation-flotation process to recycle the antimony ore, and in the test the grade of antimony is 59.21%, the recovery rate of mixed antimony concentrate Is 94.13%. HOT mining achieved the maximum intensity of the recovery of the antimony ore, which reduced the environmental

Two open-pit gold mines in Montana closed in 1998 but continue to cost the state's taxpayers millions of dollars in reclamation and water-treatment efforts. Cyanide used at these mines to leach gold from ore resulted in such high levels of pollution that people cannot use nearby water resources until they have been subjected to extensive and expensive treatment and purification.

Underground mining generally results in relatively small waste rock disposal areas ranging from a few acres in size to tens of acres (0.1 km2). These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts.

The Advantages of Open Pit Mining

Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining

Jan 09, 2012To start milling operations, dump rock was hauled from older workings at the Los Juarez antimony/silver/gold property in Queretaro, Mexico. Six samples were taken on a regular basis from approximately 19 truckloads or 420 metric tons from dump rock from an open pit called "Minas Grande."

Open pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
