A General Approach to Some Screening and Classification
网页screening has been investigated by Raiffa (1961) in a decision theory context with Bernoulli distributed variables. The search for efficient test procedures, such as group testing (see, for example, Sobel and Groll, 1966) or paired comparisons, can be a prime factor in classification problems. We exclude these possibilities as not

information on screening and classification of ore
网页Jul 18, 2013 In the present study the ore beneficiation is conducted by screening, attritioning, classification and magnetic separation. In the flowsheet, the optimised conditions are considered. The flowsheet includes crushing, grinding, attritioning with sodium silicate and screening into two size fractions, coarse −250+53 μm and fine −53 μm.
