This item is printed on demand. 66 pages. Dimensions: 9.5in. x 7.2in. x 0.2in.This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1898 Excerpt: . . . CHAPTER VIII. WORKING COST OF PROCESS. TREATMENT OF BULK ORE. The cost of treating the whole of the crushed pulp, styled bulk treatment, of course depends much on a variety of circumstances, such as (1) the nature of the ore, (2) the method of treatment and precipitation, (3) size of plant and facilities for treatment, such as proximity of mine to plant, available water power, cost of fuel, and c. , and c. The same of course applies to the treatment of slimes, tailings, fec. , and c. I will therefore content myself by giving actual examples. At the Crown mine, Karangahake, Thames, New Zealand, the cost in 1894 was, for drying, crushing, and bulk cyanide treatment of the dry ore, 14s. per ton. The plant is part agitation (the old plant erected in 1889), and percolation (the more recently erected part of the works). The difference in cost between agitation and percolation is not given, only the average cost on the total output, viz. , 14s. The cost is being gradually reduced. At the Waihi mine, Thames goldfield, New Zealand, the ore is kiln-dried, crushed dry in a stamp battery, conveyed dry to the ore vats, and leached by cyanide. Zinc precipitation is used. In 1895 the costs are given as follows: --From the above the items gold duty, freights, rents may be eliminated. The office expenses also include the mine management. The cost for reduction and cyanide treatment will be about 16s. , exclusive of royalty. At the Mercur mine, Utah, U. S. A. , the ore is dried, crushed in Walls fluted rolls, cyanided dry in coarse particles, for a total cost of 9s. 9d. ; of this cyanide and zinc accounts for 2s. 10d. The 9s. 9d. does not include office expenditure, superintendence, or royalty. Here also the cost is being now reduced. The Black Hills Gold and Silver Extraction Co. , Dakota, U. . .
