Franz Ludwig Cancrinus ... Anleitung zur Scheide- und Aufbereitungskunst der Mineralien
This 1782 German treatise by Franz Ludwig von Cancrin, published by the Andreäische Buchhandlung, teaches mineral separation and ore dressing to mining engineers and metallurgists. Its copperplate engravings show water-wheel driven stamps, crushing and washing machinery, a cannon-like boring or drilling device, and a long hall with sloped conveyors, drawn in clean, evenly spaced line work that suggests strong technical diagrams for industrial or historical subjects.
