10 Questions
The metallic constituents are easy to sample when they are carried by a few pieces in a large mass of barren material.
False
According to Prof. R.H. Richards' Rule, the weight taken for the sample should be proportional to the diameter of the largest particle.
False
In general sampling practice, the 1st sample should be cut from 5% to 20% of the ore bulk.
True
The ratio of weight of the sample to the fineness of division does not play a role in successful sampling.
False
The weight of the 1st sample should not depend on the uniformity of composition and fineness of division of the bulk material.
False
To obtain a fair average proportion of all qualities and sizes of the parent bulk material, methods of cutting out the sample are not important.
False
The Mode of Occurrence of metallic constituents has no impact on the ease of sampling.
False
Following Prof. R.H. Richards' Rule, the weight taken for a sample is directly proportional to the diameter of the largest particle.
False
In general sampling practice, it is recommended to cut out more than 50% of the ore bulk for the 1st sample.
False
The ratio between the weight of the sample and the size of the ore particle is not significant for successful sampling.
False
Explore the science and art of determining the composition of materials in terms of elements or compounds in metallurgical analysis. Learn about qualitative analysis that provides information about the identity of atomic or molecular species, and quantitative analysis that offers numerical data.
