Data Mining Tutorial: Process, Techniques, Tools, EXAMPLESNormalization: Normalization performed when the attribute data are scaled up o scaled down. Example: Data should fall in the range to postnormalization. Attribute construction: these attributes are constructed and included the given set of attributes helpful for data mining.. The result of this process is a final data set that can be used in modeling.
Extraction of Zinc | Application Of Zinc Refining ProcessThe next step in the extraction of zinc is called Roasting. The concentrated ore is finely ground into small pieces and then suspended in a rising stream of air. The sulphur content can be reduced hugely with this process. This also converts the Zinc Blende to ZnO which is way more reactive.
What Are the Disadvantages of Mining? | 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.
Mining Of Zinc ZincProcess Of Zinc Mining. At first, the zinc ore is crushed in the zinc mining equipment and the zinc ore is miledl. after it is moved to the crushing place. The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and crushed.
