Put into perspective, we will say that our 35M tailings thickener processes 10,000 mT per day of solids and uses mid range polymer dosage and costs. Table 7 then suggests that operating costs not considering maintenance would be in the range of $400,000 per year per thickener. So our increase in power consumption by selecting paste thickeners is about 10 of the OPEX.

The thickener underflow slurry must be diluted prior to leaching, and therefore barren solution at a rate of 12.8 cubic meters per hour is added to the trash screen, diluting the slurry from a 60 to a 45 solids slurry. The slurry passes through the trash screen into a recycle box which provides a means of directing flow back to the thickener feed well, or to the second leach tank, bypassing

In a major reversal, Dawn Mining Co. has discarded its plan to import millions of cubic feet of mildly radioactive waste from the East Coast to close its old uranium mill tailings pit near Ford, Wash. Instead, Dawn will fill and cap the big hole with clean dirt from 160 acres of newly acquired land adjacent to the mill site, Dawn officials said on Sep 9, 1999.

It was reported the property had 3000 feet of drifts, 200 feet of shafts and a 120 ton per day mill which processed the ore for gold, silver, copper and lead. The operation had electric power which operated the hoistspressor. Ore was hauled in the mine workings by a three ton storage batteryotive. The mine was operated during the late 1940s by 20 men until the mill burned down on
Both the tailings from the rougher and the cleaner flotation cells will be directed to the tailings thickener for thickening to approximately 60 solids prior to being pumped to the TSF. The concentrate from the copper cleaners will be re ground in a 132 kW stirred bead mill to further liberate the copper minerals. The regrind mill product will

or almost 2.0 ounces per ton and the tailings carried 1.5 ounces per ton. During 46 days in January, February and March, 1937, 18 tons treated in the test mill carried 0.5 ounce gold per ton. The mill could treat 1.5 tons per day, so that not all the rock mined was milled, The vein material milled was taken from various places on each of the four levels. Reportmends the expenditure of
The nominal design treatment rate is 4,000 tonnes per day of ore on a 24 hour per day schedule, but Alamo Dorado regularly exceeds this processing rate. The mines tailings treatment process recovers approximately 45 of the sodium cyanide used and also neutralizes mill tailings, thus reducing the mines environmental impact and reclamation costs.

Already 250,000 tons of the ore were ready for breaking and to be hauled to the mill, hauling and milling expenses totalling about $7.50 per ton with gold recovery running about 90 . The profit on a 100 ton per day schedule was expected to be $7 per ton. Detloff also filed on another mill site, called the Detloff, adjoining the Journigan site

The Mill is operational and can operate at up to 440st/day, including tailings storage. It is located less than 4 miles from the Crescent Mine Property. Crescent is guaranteed up to 330 st/day, or 75 of plant capacity for the life of the Mill, any excess capacity if available, and access to the tailings for use for backfill. The current plan would be for the Crescent Mine to provide 250st
The Petrotomics Uranium Mill began operation in 1962 as a 500 ton per day mill. In 1968, the mill was expanded to 1,000 tons per day production by the addition of thickeners, leach tanks, and another solvent extraction circuit. In 1970, the mill was expanded again to a capacity of 1,500 tons per day
To get the mill to its current capacity of 100 metric tons per day, a thickener is being constructed on site to control the pulp density, and one additional leach tank will be built on site.
