Instead of taking a conventional solution-sales approach, he used an “insight selling” strategy, revealing to the customer needs it didn’t know it had. Research in practice.
SMRI views solution mining as mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns. ...
Data mining is an important part of knowledge discovery process that we can analyze an enormous set of data and get hidden and useful knowledge. Data mining is applied effectively not only in the business environment but also in other fields such as weather forecast, medicine, transportation, healthcare, insurance, government…etc. Data mining has a lot of advantages …
And, finally, the suitability of a location largely also depends on the ability to utilize or to dispose of the brine generated by the solution-mining process: The creation of 1 m 3 of cavity generates c. 8 m 3 of brine; this means that around 4 10 6 m 3 of brine are generated when constructing a cavern with a typical volume of 5 10 5 m 3 ...
Jun 16, 2020 In 2007, a submersible with a large drill descended 1,600 meters (5,250 feet) into the sea off the coast of Papua New Guinea (PNG), landing near a network of hydrothermal vents that host an array ...
Jul 24, 2019 The main advantage of neural networks lies in their ability to outperform nearly every other machine learning algorithm, but this comes with some disadvantages that we will discuss and lay our focus on during this post. Again, decide whether to use deep learning or not depends mostly on the problem at hand.
Project Amazonia: Solutions - Mining Problem: . Excessive unregulated mining is causing serious harm to the Amazon ecosystem. Hypothesis: . A decrease in illegal mining, along with better practices for legal mining, would decrease negative impact on the environmental without significantly disrupting the product supply.

Michael P. Paidoussis, in Fluid-Structure Interactions (Second Edition), 2014 4.8.4 Solution mining and carbon sequestration. Solution mining refers to the production of salt (or potash, or other soluble products) by pumping water into subterranean salt deposits, found in many parts of the world, dissolving the salts and pumping the brine to the surface for drying and further use.
Mining will also not be sustainable in the long run. Most resources that are mined are non-renewable and will become depleted sooner or later. At one point in time, it will simply no longer be reasonable from an economic perspective to engage in mining and therefore, mining can be regarded as a short-term solution more than a long-term plan.
Nov 13, 2020 Disadvantages of Cloud Mining. Some cloud mining functions tend to commit fraud when the miners or users also share information regarding their keys and digital wallet. In cloud mining, the operations of miners become vulnerable and transparent. There is no control and suppleness in cloud mining. Cloud mining is primarily a service provider.
3 Drawbacks and solutions In the association rule mining area, most of the research efforts went in the first place to improving the algorithmic performance , and in the second place into reducing the output set by allowing the possibility to express constraints on the desired results.
Jan 28, 2013 The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.

Jan 18, 2016 Problems of Solution Mining : Little control of the solution underground and difficulty in ensuring the process solutions do not migrate away from the immediate area of leaching. Main impact of evaporite ISL is derived from surface or shallow groundwater contamination in the vicinity of evaporation ponds.
Since mining often includes the extraction of metals and other resources deep under the surface, it can lead to serious erosions. These erosions may in turn lead to a state where the eroded land is no longer suitable for human use like housing or farming since the soil is too unstable and poses too many dangers of further erosion.
Aug 04, 2015 The disadvantages of mining include harm to air pollution, water pollution, loss of usable land, destruction of animal habitat, and harm to local communities and the miners themselves. While mining produces the resources needed for fuel, electronics, and other items as well as jobs, companies often don’t factor the harm mining can do into their decision making.
