Another process of formation of sedimentary rocks is by evaporation of sea water. Salts are given out during the evaporation of sea water and such salts form salt crystals which settle out in layers. It is in this process rock salt is formed. Biogenic sediments also form sedimentary rocks.
Surface mining is used to produce most of the coal in the because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the topsoil and layers of .

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

It is quite probable that the charnockite mentioned in this study are garnetiferous charnockite found adjoining to khondalite belt. The bauxite profile derived from khondalite and garnetiferous charnockites have vast areal extent and sizeable thickness. The bauxitization process is mostly controlled by geomorphic features. The nature of weathered
Process mining is a family of techniques in the field of process management that support the analysis of business processes based on event logs. During process mining, specialized data mining algorithms are applied to event log data in order to identify trends, patterns and details contained in event logs recorded by an information system.
