Getting Gold: A Practical Treatise for Prospectors, Miners and Students — Key Ideas to Explore
Edition facts
J. C. F. Johnson’s Getting Gold opens with a frank acknowledgment that gold mining, while “always fascinating,” is “not as invariably profitable.” The author, a Fellow of the Geological Society and member of the Australasian Institute of Mining Engineers, draws on thirty years of experience to produce a compendium of practical information. The book’s preface notes that an earlier work, Practical Mining, sold ten thousand copies in Australasia and is now out of print; this revised edition aims to expand that scope. Johnson addresses directors, managers, mill operators, and prospectors, promising “original practical discoveries” alongside selected methods. The tone is direct and experience-based, with chapters on everything from prospecting to the chemistry of ore treatment.
From Prospecting to Refining: A Hands-On Approach
The book’s structure follows the gold-winning process from start to finish. Early chapters cover prospecting and the nature of gold deposits; later ones detail crushing, amalgamation, and secondary extraction methods. Johnson includes a chapter on “Rules of Thumb” with practical hints for everyday mining problems. The excerpts show a strong emphasis on chemical and mechanical specifics: for example, he describes an experiment where a ball of amalgam weighing 1583 grains is pressed through calico, yielding precise measurements of mercury expressed and gold recovered. He explains the rationale behind each step—squeezing out mercury to prevent slagging, then calcining before smelting—and notes that his laboratory treatment was “intended to be on a practical basis.” This blend of hands-on trial and clear explanation characterizes the entire work.
The Voice of Experience: Caution and Specificity
Johnson’s writing is marked by a cautious, advisory tone. He warns that “the treatment which will yield most satisfactory results with a certain class of gangue on one mine will sometimes … prove a disastrous failure in another.” He praises a mine manager who “strongly discountenanced the purchase of any extracting plant until he was fully satisfied as to the character of the bulk of the ore.” This emphasis on site-specific analysis reflects his practical background. The excerpts also reveal a methodical approach to problem-solving: when discussing slimes that carry off fine gold, he lists the offending compounds—titanic iron, tungstate of iron, hematite, limonite, aluminous clay—and explains how they behave under crushing. The book does not shy from technical detail, but Johnson often translates chemical symbols into plain language for readers unfamiliar with them, as when he glosses FeCO₃ as “carbonate of iron.”
A Compendium for a Growing Industry
Published in 1896, Getting Gold reflects the expansion of the gold-mining industry since the early 1890s. Johnson aims to make the book “a compendium, in specially concrete form, of useful information.” The preface cites a review from the London Mining Journal praising his earlier work for packing “so much interesting matter combined with useful information in so small a space.” This new edition is larger in scope, yet retains a compact, rule-of-thumb style. The excerpts show a blend of original research (such as the amalgam-pressing experiment) and compiled knowledge. Johnson’s credentials—F.G.S., member of the Aust. Inst. of Mining Engineers—lend authority, but the book’s value lies in its direct applicability. For modern readers, it offers a window into late-19th-century mining practices and the mindset of a practitioner who valued prudence and empirical testing over untested theory.
Readers approaching Getting Gold should expect a technical manual, not a narrative. The book rewards those who read with attention to the chemical and mechanical details Johnson provides. His repeated insistence on testing ore before committing to a treatment plan remains sound advice. The work is best used as a reference, dipping into chapters as needed, rather than read straight through. For students of mining history, it offers authentic period methods and a clear, no-nonsense voice.
