Combination of separation methods and data mining ...

Mahalanobis Distance (MD) method is one of the multivariate techniques in which anomalous areas are separated based on Mahalanobis distances. The covariance matrix quantifies the shape and size multivariate data. So the Mahalanobis distance is the well-known distance measured to separate anomaly which takes into account the covariance matrix.

25.4 Separating minerals from waste | Mining of mineral ...

Exploration methods are used to find, and assess the quality of mineral deposits, prior to mining. Generally a number of explorative techniques are used, and the results are then compared to see if a location seems suitable for mining. Remote sensing is the term used to gain information from a distance.

Mineral Comminution and Separation Systems

2020-8-25 · Comminution processes are generally preliminary to the separation processes.

Separation Techniques | Classification of Matter

A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture’s constituents. In some cases, a separation may fully divide the mixture into pure constituents.
