Sinossi
Excerpt from The Hunt and Douglas Process for Extracting Copper From Its Ores: With an Appendix Including Notes on the Treatment of Silver and Gold Ores, and a Plate
The use of the sulphurous acid fumes, which thus serve to supply the losses of protochlorid of iron, need not be resorted to except in treating native carbonates or oxyds of copper, or such ores as contain carbonates of lime or magnesia or oxyd of lead or of zinc, all of which cause a loss of the protochlorid of iron. In such cases the best mode of applying the sulphurous acid is by using stirring tanks and passing the gas over the sur face of the liquid, which is agitated during the solution of the copper. The gas should be as little diluted with air as possible. If the roasting kiln or muffle furnace be connected with the stirring tank by an earthenware tube which enters either the cover or the side of the tank at a point opposite to that by which a wooden tube (best connected with a fine) gives exit to the unconsumed gas, a sufficiently rapid current of the gas will be kept up, and will be readily absorbed by the liquid in the tank.

The book describes in detail a method of chemically separating copper from its ores and extracting it to a pure, usable state known as cement copper or blister copper. The book also contains information on the preparation and use of iron sponge, an important reagent in the Hunt and Douglas process. This book will be of interest to historians of industry, those interested in the development of chemistry, and anyone seeking to learn more about copper extraction. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Codice articolo 9781332290970_0
