A Text-book of Assaying: For the Use of Those Connected with Mines.

The Text-book now offered to the public has been prepared to meet the existing want of a practical "handy book" for the Assayer. To mining men the word "assaying" conveys a sufficiently clear meaning, but it is difficult to define. Some writers limit it to the determination of silver and gold, and others imagine that it has only to do with "furnace-work." These limitations are not recognised in practice. In fact, assaying is becoming wider in its scope, and the distinction between "assayers" and "analysts" will in time be difficult to detect. We have endeavoured rather to give what will be of use to the assayer than to cover the ground within the limits of a faulty definition. At first our intention was to supply a description of those substances only which have a commercial value, but on consideration we have added short accounts of the rarer elements, since they are frequently met with, and occasionally affect the accuracy of an assay. Under the more important methods we have given the results of a series of experiments showing the effect of varying conditions[Pg vii] on the accuracy of the process. Such experiments are often made by assayers, but seldom recorded. Statements like those generally madethat "this or that substance interferes"are insufficient. It is necessary to know under what conditions and to what extent. ......Buy Now (To Read More)
