Book Description
2018 Reprint of 1923 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. d104 in English and Arabic. Reprint of the first edition of this medieval Arabic work on alchemy, prepared by noted British historian of Islamic science Eric Holmyard (1891-1959) using the three manuscript copies of the work known to be extant, together with a manuscript of the Persian commentary by al-Jildaki. Almost nothing is known of al-'Iraqi other than that he was probably active in Mamluk Egypt or Syria during the reign of Sultan Baybars in the late 13th century, though his "'Cultivation of Gold' is valuable because it contains a clear account of the Muslim theory of transmutation, written by a man who realized the importance of experimental work. Its main argument is that all metals differ from one another only by certain unessential properties which can be removed by suitable treatment. The metallic substance free from all such accidental and unessential properties is represented by gold. A Very Scarce Book on Arabic alchemy.

Book Description
The author has dedicated many years of his life to the reconstruction of this work as manager of a gold mine with a view that this book would serve as a practical guide for young practitioners as well as for those who manage gold mining operations in Ethiopia and elsewhere. As it is written in clear and lucid language, it is helpful and convenient for practitioners and professionals to make utmost use of it as a quick referencing guide in their efforts to maximize the quantity and quality of gold mining production. The sharing of experiences of leaders and managers in such a manner will have a profound contribution to the sustainable growth of professions as well as institutions. This act is worth emulating. Based on the author's engineering, science, aviation, and aerospace background, the author has provided in great detail how gold is processed from ore/rock to marketable bullion bars for the benefit of all those engaged in gold mine operations. The practical examples and the detailed description of gold processing with proper mitigation to potential impacts on the community and environment make the book an excellent management/leadership tool for practitioners in the gold mine industry.
