Chat OnlineAs in all mining operations the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite) the ore is crushed and ground to liberate the valuable minerals from the waste ( gangue ) minerals. It is then concentrated using

Chat OnlineOnce a decision has been made to go underground the specific mining method selected depends on the size shape and orientation of the ore body the grade of mineralization the strength of the rock materials and the depths involved. For example if the ore is very high grade or carries a high price then a higher cost method can be used.
Chat OnlineSurface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining. In fact about 90 percent of the rock and mineral resources mined in the United States and more than 60 percent of the nation s coal is produced by surface mining techniques.
Chat OnlineMost underground coal is mined by the room and pillar method where by rooms are cut into the coal bed leaving a series of pillars or columns of coal to help support the mine roof and control the flow of air.Generally rooms are 2 000 feet wide and the pillars up to 300 feet wide. At least 60 feet of coal was left between an underground mine and the surface if not the surface had a higher

Chat OnlineThe number of input variables or features for a dataset is referred to as its dimensionality. Dimensionality reduction refers to techniques that reduce the number of input variables in a dataset. More input features often make a predictive modeling task more challenging to model more generally referred to as the curse of dimensionality.

With Reclamation is generally concurrent with mining. Strip mining is commonly used for mining coal seams and phosphate beds. In hilly terrain the mining of the overburden and the deposit
Chat OnlineThe role of data exploration. Before it can conduct analysis on data collected by multiple data sources and stored in data warehouses an organization must know how many cases are in a data set what variables are included how many missing values there are and what general hypotheses the data is likely to support. An initial exploration of the data set can help answer these questions by
