Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.
The openpit copper mine is approximately miles long, miles wide, and 1,200 feet deep, with 40foothighbenches (narrow, steplike strips cut into the side of the open pit). Early copper mining began at the site in 1900, with open pit stripping beginning in 1959.

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached ...
Byproduct A secondary metal or mineral product recovered in the milling process. C. Cable bolt A steel cable, capable of withstanding tens of tonnes, cemented into a drillhole to lend support in blocky ground. Cage The conveyance used to transport men and equipment between the surface and the mine .
Conventional process route The transition to underground mining has enabled 50,000 tpd of conventional crushing, milling and flotation capacity. Copper and magnetite are recovered on behalf of Foskor (a neighbouring mining company) by tollprocessing 20,000 Tpd of marginal ore from stockpiles from the open pit operation.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

The first stamp mill in the was built in 1829 at the Capps mine near Charlotte, North Carolina. They were common in gold, silver, and copper mining regions of the US in the latter 19th and early 20th centuries, in operations where the ore was crushed as a prelude to extracting the metals. They were superseded in the second half of the 19th ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
This new mine plan was a result of a detailed, sixmonth engineering study and forms the basis of an updated NI 43101 compliant reserve (see News Release May 5, 2015: Taseko Announces Improved Economics At Its Gibraltar Copper Mine). The new mine plan took into account lower milling costs as a result of the modernized processing facilities.
The Sepon copper operation produces approximately 80,000 tonnes of copper cathode (copper sheets) per year from the nearby Khanong and Thengkham ore bodies. Crushing and milling Runofmine (ROM) ore is crushed and then milled, which reduces the diameter of the pieces of rock from about 500mm to about (106 microns).
