Mill tailings were disposed of in an area below the mill. The concentrated ore and the direct shipping high-grade ore were loaded into bags for shipment by rail. In 1916 an innovative ammonia leaching plant was constructed to further recover the copper oxides from the tailings. In 1925, flotation was introduced to boost total recovery to 96%.
Copper Cliff, Greater Sudbury. View 2: A cross-section of the underground workings of the Copper Cliff Mine, looking west. Much of the remaining ore is in the deepest parts of the mine.

White Pine Copper Company built and operated, from August, 1962 through May, 1963, a pilot plant to recover copper using a cyanide percolation leach of the sand fraction (+400 mesh) of the mill tailings. The pilot plant runs were metallurgically successful and preliminary engineering studies for a full scale operation were completed under contract by an outside engineering firm.
Copper tailings if the copper with high heavy metals content, the separation will be easier and apply the process of flotation. If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly. Get Price
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Uranium Mill Tailings Uranium mill tailings are primarily the sandy process waste material from a conventional uranium mill.This ore residue contains the radioactive decay products from the uranium chains (mainly the U-238 chain) and heavy metals. As defined in Title 10, Part 40, of the Code of Federal Regulations (10 CFR Part 40), the tailings or wastes produced by the extraction or ...
between the volume of silver (Ag) and copper (Cu) tailings along SBC. The tailings locations were influ-enced by their proximity to the silver and copper mills, which were, in turn, closely related to the structure of the Butte deposit. The Butte Deposit The 68–78 Ma Butte ore deposit is located in the
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
From the rod mill the material proceeds to the cobber magnetic separators. Any non-magnetic material which has been released by the rod mill is separated and sent to the tailings thickener. Magnetite iron ore particles are separated by the magnetite separator from the gangue (waste material) minerals in the cobber magnetic separators.
Outside of the Mission South Mill, trucks dump the ore into the primary crusher which reduces the rocks to 8 inches or smaller. Inside the mill, the ore is mixed with water in two rotating SAG mills which use the larger rocks and 8-inch steel balls to reduce the ore to about 10 mm or smaller.
A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bi-metallic) formulas

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
