Excerpt from The Fire Assay: Of Gold, Silver, and Lead in Ores and Metallurgical Products

The following pages present a system of assaying, intended to cover determinations of the precious metals (silver and gold) and of lead, according to methods quite commonly recognized in the Rocky Mountain States as suited to ores and products containing the just-named metals.

In reading books on the subject, the beginner in assaying is embarrassed in deciding which one of the various prescribed charges he is to employ. It has, therefore, been the aim of the author in this book to carry through a single system, which, while not the only one, would at least be definite and clear to the learner.
