Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine.
mining refers to discover new patterns from a wealth of data in databases by focusing on the algorithms to extract useful knowledge [7]. Figure 2 Data Mining and the KDD Process(Source: Fayyad,, 1996) Based on figure 2, KDD process consists of iterative sequence methods as follows [7, 9]: 1.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
as mining progresses through the orebody, from oxides through to sulphides, and through other mineralogical geozones Downstream processes are often seen as the valuecreating parts of the chain. If this is the case, then at a minimum the plant needs a consistent feed in terms of volume, hardness, quality, size, and grade in order to perform to design.
