Book excerpt: Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "The Fire Assay of Gold, Silver and Lead in Ores and Metallurgical Products." Unavailable since 1907, this important publication was originally published by the Mining and Scientific Press and was designed to introduce miners and prospectors of gold, silver and lead to the art of fire assaying. Topics include the fire assaying of ores and products containing gold, silver and lead; the sampling and preparation of ore for an assay; care of the assay office, assay furnaces; crucibles and scorifiers; assay balances; metallic ores; scorification assays; cupelling; parting' crucible assays, the roasting of ores and more. This classic provides a time honored method of assaying put forward in a clear, concise and easy to understand language that will make it a benefit to even beginners.

Excerpt: ...height about 4.5 cen Transactions of the American Institute of Mining Engineers, October, 1898. Mr. Chism claims as original the use of silver for receiving mercury (though this was suggested before), and the use of a separate vessel to cool the receiving surface by contact. t See Fig. 39.

O, cooling-cup. tinieters. The mouth of the crucible should have an even surface. Shield.--To prevent the direct heating of the upper part of the crucible and silver-foil, use a circular tin shield about 13 centimeters in diameter, with a hole in the center large enough to pass the crucible partly through, leaving about 1 centimeter of the crucible above the shield. The Recipient.--Use a piece of pure silverfoil (rolled silver) about 5 centimeters square, and about 0.02 millimeters in thickness, on which to receive the mercury. It should be large enough to cover the crucible and leave a margin all round of about one-half centimeter. Cooling-aip.--For cooling the silver-foil, use a silver dish of a wide pattern like an evaporating-dish. Silver is a good heat-conductor. A copper dish could be used. The bottom of the dish should be a little larger than the mouth of the crucible. Keep the bottom of the dish polished to enable you to discover any mercury that might soak through the silver-foil. Should this happen, drive off the mercury from the dish by heat, and repeat the assay with new silver-foil and less ore. Flux.--Use iron filings, the finer the better. They should pass a 60-mesh sieve. Remove most of the grease with strong alcohol, and then heat them to...
