Under certain mining conditions peculiar to the kind of coal, and the number and location of the mines relative to the associated preparation plant, it is sometimes desirable to separate pieces of coal from pieces of shale (rocks) at the mine site by a dry process.
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities.
Oil Shale "The underground supply of oil cannot much longer be depended upon to supply the ever increasing demand,.pointing unerringly to the one permanent supply of the raw material which we have the deposits of oil
In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal. Supplementary materials are used to adjust the composition of the raw meal but cost and availability are likely .
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Comprehensive steel raw material prices and investment information. Iron mining company stock quotes, iron and coking coal price charts and news.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
The shale gas revolution has led to strong falls in energy prices, reducing significantly the raw material costs of the US petrochemical industry. Between 2008 and 2012, US gas prices fell by two thirds. Ethane comes from natural gas liquids (NGLs) contained in shale gas, .
Knowing the accurate production of material flows and collections one can draw a final layout for the separation plant. Results In the case of nonselective mining, oil shale has to be processed in a concentration plant to achieve the desired quality for customers. Oil shale is concentrated in heavy media separation drums.
Executive Summary: Volatile and unstable global markets have widespread implications for manufacturing organisations. From rising energy costs to unexpected fluctuations in raw material price levels, unforeseen obstacles are destabilising supply chains and making it difficult for manufacturers to remain in the black.

The US shale boom has led to considerable growth in the availability of light products in the US – natural gas and petroleum gas are products that lend themselves to producing petrochemicals.
List of Bulking/Swell factors for various materials. The swell factor expressed in percentage is the amount of volume increase from Bank volume (undisturbed, in place state) to Loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation.
The mining industry consumed an estimated 551 trillion British thermal units (Btu) in 2002. 3 Major energy sources include fuel oil, electricity (purchased and produced onsite), coal, and natural gas. The energyintensive nature of mining is evident by the recovery ratio of the various materials being mined.
Critical review, comparative evaluation, cost update, and baseline data development services in oil shale mining, insitu liquefaction, and above ground retorting processes from the environmental, permitting, and licensing viewpoints. Volume I. Oilshale retorting process engineering
On the one hand, better quality of the raw material or fuel allows reduction of costs for transportation, processing and burning, and, on the other hand, it ensures higher quality of processing and cleaner environment. Hence, with regard to the utilization (processing, burning), mineral raw material of higher quality is beneficial.
Shale oil extraction is usually performed above ground (ex situ processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (onsite or in situ processing) by applying heat and extracting the oil via oil wells.
