Excerpt from The Recovery of Nitrate From Chilean Caliche: Containing a Vocabulary of Terms an Account of the Shanks System, With a Criticism of Its Fundamental Features, and a Description of a New Progress
The introduction Of the Shanks system resulted in notable economies, as compared with previous practice, with the result that caliche of lower ley could be treated at a profit. The grade Of the material sent to the maquinas for the 20 years subsequent to the introduction of the Shanks system was probably fixed at a minimum of over 25 per cent., and in most cases averaged well over 30 per cent. Nitrate.
With the reduction in grade Of caliche being treated, a considerable decrease in percentage extraction Of nitrate, by existing methods, was observable. At all times, however, a veil Of mystery has been drawn over the actual results Of practice, and reliable figures were impossible to Obtain.

Excerpt from The Recovery of Nitrate From Chilean Caliche: Containing a Vocabulary of Terms an Account of the Shanks System, With a Criticism of Its Fundamental Features, and a Description of a New Progress
Since the date of the first manufacture of nitrate from the caliche found in the (then) Peruvian pampa, during the early years of the 19th century, the developments in the industry have been almost entirely in connection with the application of new and improved processes for the purpose of making profitable the treatment of material of decreasing nitrate content. The average ley, or nitrate percentage, of the caliche treated during the first fifty years probably averaged at least 75 per cent. In the most primitive method of beneficiation the rich caliche was boiled with water or mother liquor in large copper pans by the direct application of heat; and the nitrate was then crystallised from the resulting strong solution.

The Recovery of Nitrate From Chilean Caliche (Classic Reprint)
Print-on-DemandAnbieter: Forgotten Books, London, Vereinigtes Königreich
Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book offers a fresh perspective on nitrate recovery from Chilean caliche. The author, a chemical and metallurgical engineer with extensive expertise in the field, presents a critical examination of the widely used Shanks system, highlighting its limitations, and proposing an innovative new process that promises to revolutionize the industry. The author emphasizes the need for a more efï cient, less wasteful approach to nitrate extraction, given the dwindling availability of high -grade caliche deposits. The proposed new process focuses on optimizing extraction and evaporation stages, utilizing innovative heating methods, and incorporating continuous leaching techniques. The book delves into the fundamental principles of leaching, providing a solid theoretical foundation for the proposed process. It also discusses the importance of accurate accounting and sampling methods to ensure precise monitoring of nitrate losses and recoveries. The author's vision extends beyond the technical aspects of nitrate extraction, encompassing the broader implications for the Chilean economy and the global fertilizer market. The book argues that the efï cient recovery of nitrate from low -grade caliche and ripio dumps could signiï cantly extend the life of the Chilean nitrate industry, reduce production costs, and enhance the availability of affordable fertilizers for agricultural productivity. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
