We offer them with either a hammer mill or a ball mill. Our 4-5 tph system comes with a ball mill only. The hammer mill version of our turn-key ore processors is less initial cost, but higher maintenance cost ($10-15/ton, plus down time). It will produce ground material with 70% passing a 30 mesh screen and 50% passing a 50 mesh screen.

The cost data above referred to has been compiled from actual operating results and shows the cost of milling both for the old 50-ton plant and the new 100 ton concentrator, as is now in use. Note the reduction in milling costs through the use of the new flowsheet which includes an 8-cell "Sub-A" Flotation Machine.

Example: A mill in closed circuit with a classifier receives 300 dry tons of crude ore per day, and the percentages of solid are respectively 25, 50, and 84% in the classifier overflow, feed to classifier, and sand, equivalent to L: S ratios of 3.0, 1.0, and 0.190. Then the circulating load ratio equals

quantity of mineral ore (called the 'strip ratio') is usually greater than one, and can be much higher. For example, if a proposed mining project involves the extraction of 100 million metric tons of mineral ore, then the proposed mining project could generate more than one billion metric tons of overburden and waste rock.

recovery underestimated, and that the decision to go with milling may have been incorrect. Differential Recovery Is Not Sufficient To Justify Added Investment A recent review (Kappes, 1998) concluded that for a "typical" Nevada-type ore body with ore grade of 3.0 grams gold/tonne (0.088 oz/ton), the mill recovery would have to be 21% higher than

Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich.
