Master this essential reference for measuring precious metals in ore with precision.
This is a comprehensive manual for metallurgists, mine captains, and assayers who need reliable methods to determine the exact amounts of gold and silver in a sample.
The book blends mechanical preparation with chemical testing, guiding readers from grinding ore to a fine powder to performing complex analyses. It covers how to set up and use furnaces, fluxes, and the blow-pipe, as well as humid analysis and cupellation. A detailed, copious table shows how to translate assay results into ounces, pennyweights, and grains for a ton of ore.
- Clear, step-by-step procedures for mechanical and chemical assay operations.
- Practical guidance on furnaces, crucibles, fluxes, and flux actions.
- Techniques for humid analysis and the interpretation of results.
- A complete assay table that converts metal yield into precise units.
Ideal for readers involved in mining, metallurgical testing, or historical study of ore analysis techniques.
