Excerpt from A Treatise on Concentration of All Kinds of Ores: Including the Chlorination Process for Gold-Bearing Sulphurets, Arseniurets, and Gold and Silver Ores Generally This work is designed to show the present condition of the art of concentration; putting forth the principles on which it is founded, without entering into scientific considerations. To make the work complete as far as possible, the processes of Dry Dressing are also brie y described therein and the whole is so arranged, and illustrated by diagrams, as to enable every one to be successful in concentrating ores. As the method of reduction by stamping is considered import ant, the erection and treatment of stamp-works, as also the construction of grinders, are treated in full, and explained by numerous drawings. Among the concentrating machines, the preference has been given to self-discharging continuous contrivances; and of these again to such as have been sufficiently investigated as to their efficiency, the amount of water and of power required to run them, their proportion of loss, etc. - circumstances entirely neglected with California inventions, - the relative data of the latter being mere guess-work, and unreliable. A short description of many less important contrivances may appear super uous, but the knowledge of them may prevent many persons from spending time and money, as has often happened. On inventions supposed by them to be new. The description of J igging Concentration, important to Eastern lead mines, is furnished with diagrams of new continuous machines.
