In the mining industry, lime products are used to refine and condition metal ores and nonferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.
The West ia Coal Industry provides about 30,000 direct jobs in WV, including miners, mine contractors, coal preparation plant employees and mine supply companies. Underground mines in 2009 produced 87 million tons with 33 million tons from longwall mining.
Chemicals of Concern: Coal mining effluent contains a high load of total suspended solids, total dissolved solids, calcium carbonate, and heavy metals, contaminating surface water and ground water. Heavy metals accumulate in water, soil, sediment, and living organisms.

Coal production. Coal mining, the process of extracting coal from the ground, is a common economic activity around the world. Coal is removed in a number of ways including: contour mining, strip mining, and mountaintop removal. After undergoing a cleansing process, coal is typically burned in order to produce electricity.

Mine Tailings Waste Leaching Groundwater Contamination. During the period, 53,566 million cubic yards of overburden were generated by surface mining for coal, and 75 percent of this in just nine statesKentucky, Pennsylvania, Illinois, Indiana, Alabama, West ia, ia, Tennessee, and .
Environmental consequences of mountaintop coal mining. In some freshwater food webs, sulfate has accumulated to four times the toxic level, which can cause deformities in larval fish and expose birds to reproductive failure when they eat fish. Animals feed on streambed algae that can concentrate sulfates as much as 800 to 2,000 times that in water.
Current coal mining and processing procedures produce a significant quanity of fine coal that is difficult to handle and transport. The objective of this work is to determine if these fines can be economically pelletized with calcium hydroxide, a sulfur capturing sorbent, to produce a cleanburning fuel for fluidizedbed combustors or stoker boilers.
Coal mining began in Pennsylvania in the mid1700's, fueled by the Colonial iron industry. Bituminous (soft) coal was first mined in Pennsylvania about 1760 at "Coal Hill" (presentday Mount Washington), just across the Monongahela River from the city of Pittsburgh.
