Industrial Progress in Gold Mining: A Review of the Gold Mining Industry in the United States - Couverture souple
Présentation de l'éditeur
The presentation of this volume to the public interested in mining for the precious metals will ej(cuse the absence of a prefatory attempt to harmonize realization with expectation. The work is without pretension, and is yet not inutile, either in facts or the burthen of information. Confessedly, on all sides, the subject is one of great commercial importance. The development of a serious default in the customary methods of beneficiating ores for the precious metals, when followed by the commendation of a remedy as comprehensive as the default is universal, must interest a large class of inquirers and intending investors. In this view the Mears Chlorination Company regard INDUSTRIAL PROGRESS IN GOLD-MINING as a very valuable r Ssumi of the present condition of the industry. They are persuaded readers will agree with them in this opinion, especially after perusing the articles discussing the treatment of auriferous sulphides and the causes of waste in manipulating ores, which contain these as the most abundant source of auric wealth the characteristic ores in the rocky areas of the precious metals. If right in this supposition, thanks are due to the author for so much useful work in a new direction and to the Company for presenting the result in the acceptable form of the present volume.
