Synopsis

Master the practical art of assaying gold and silver with time‑tested methods.

This edition presents detailed guidance for the preparation, fusion, and testing of ore, bullion, and various metal mixtures. It emphasizes hands‑on techniques, measurement accuracy, and reliable results that professional assayers rely on.

The book explains how to set up assay weights, use different systems (grain/gram and assay ton weights), and read complex tables that convert bead weights into ounces per ton and bar values. It also covers melting in crucibles, managing furnaces and mufﬄes, and adjusting fluxes to handle iron oxides, silicates, and sulfides. Throughout, the focus remains on clear, practical steps for real mine lab work.

How to prepare and calibrate assay weights and balances for accurate measurements
Step‑by‑step fusion, slag control, and button formation in different flux systems
Interpreting assay tables to determine ounces per ton and bullion values
Troubleshooting common issues in melting, slag, and metal separations

Ideal for readers of mining and metallurgical reference works, especially those seeking hands‑on techniques for gold, silver, and related metals.
