What reading level is Mine Sampling And Valuing a Discussion of the Methods Used in Sampling And Valu book?
To quickly assess the difficulty of the text, read a short excerpt:
Sometimes the sample, if large, can be divided a second time without further crushing, but in this the engineer must be guided by his experience, always bearing in mind that the greater the fineness, the more accurate the result. In some cases it may be advisable to crush the whole remaining material to pass a 10-mesh screen before making the division to secure the weight required for the final pulp.
A discussion of the methods of preparing a sample for assay will not be complete without some b...rief reference to the well known method of quartering. Of course, most books on assaying deal with this subject more or less in extenso, and I only wish to briefly refer to it to round up the present discussion.
An engineer may find himself in the field without having pro- vided mechanical dividers of any kind, yet large samples must be reduced in bulk in order to permit of economical transportation.
PREPARATION OF SAMPLES 73 Without mechanical dividers, the only thing that is left to be done is to quarter the sample on a canvas sheet or on an ordinary oil cloth, what is known in England as American cloth, which can be bought at a general merchandise store, practically in any part of the world.
