Analytical Methods Selection Criteria

The Mode of Occurrence of the Metallic constituents is very large bulk + uniform in composition. Difficult to sample when metal is carried by a comparatively few pieces in a large mass of barren material. Imperative to reduce everything to smaller size and thorough mixing before taking the 1st cut for samples. Conditions Governing Sampling IV. The Ratio of weight of Sample to the fineness of ______

For successful sampling, a definite ratio must exist between the weight of the sample and the size of the ore particle. Prof.R.H.Richards’ (MIT) Rule: 'the weight taken for sample shall be proportional to the square of the diameter of the largest ______'

The Ratio of weight of the 1st Sample to the total weight of the bulk will depend upon the uniformity of composition and fineness of division of the bulk material. General Sampling Practice: Cut out the 1st sample from 5% to 20% of the ______ bulk

The Methods of cutting out the Sample aim to obtain a fair average proportion of all the different qualities and sizes of the parent ______ material

In metallurgical analysis methods, it is essential to ensure the ______ of the sample to maintain accuracy in results

Quantitative analysis in metallurgy involves precise measurement and ______ of metallic elements in a given sample

Selection of analytical methods in metallurgy should be based on the ______ of the material being analyzed

Identification is crucial in metallurgy to determine the ______ and properties of minerals present in a sample

The ______ of minerals can greatly impact the sampling process in metallurgical analysis

Understanding the ______ of the ore particles is fundamental for accurate sampling and analysis in metallurgy
