    The mill was fed by two aerial tramways bringing copper ore from 4-5 interconnected mines some 4,000 feet above on Bonanza Ridge. These mines, the Bonanza, Mother Lode, Glacier, Jumbo, and Erie were linked by a combination of aerial tramways or some 70 miles of underground tunnels and workings.

    The feed material is supplied as a slurry from below by a feed pump. The mineral particles, which become smaller during the grinding process, rise up in the mill cylinder and leave the mill via a natural overflow on top. Gravity supports to retain the grinding beads, which have a higher density than the slurry, in the milling chamber.

    As a result, the copper and gold net smelter returns for copper concentrate sold to Smelter A are equal to $511 and $515 per tonne of concentrate, or $48.01 and $48.37 per tonne of ore. When these numbers are divided by the mill feed grade, the copper and gold NSR factors are equal to $20.69 per % Cu and $18.97 per gram of gold.

    variables: ore feed rate, trim water flow and sump water flow. The first row shows the response of particle size measurement (PSM) to the manipulated variables. Reducing ore feed rate, or adding water either to the mill or to the sump reduces the PSM as expected. However, the gain with trim water is higher than with the sump water.

    May 28, 2018 High-grade ore is delivered to stockpiles near the mill feed chute. A two month stockpile of this high grade ore is maintained and loaders provide an optimized blend to the mill. The two month stockpile also allows the mine to develop in an orderly fashion without “chasing” ore in the phase to meet short-term demands.

  • Industrial Grinding Estimation Of Blended Ore From

    The influence of feed size on mill performance naturally follows from the fact that a considerable part of the grinding media (especially in autogenous mills) derives from the feed ore. Any change in the feed distribution will therefore result in a change in the grinding media size distribution. This in turn
