Read MoreSulphide ore will be processed on-site by conventional flotation plant with the capacity to treat 20 million mt/y ore to produce copper concentrates. This concentrate will go to off-site smelters. Lumwana will produce copper, in concentrate, equivalent to 169,000 mt/y of copper Expectedly these ores when concentrated produce quite different flotation concentrates that respond to further processing differently. Merensky concentrates will generally have a higher Pt/Pd ratio and contain significant amounts of nickel and copper UG2 concentrates contain a larger percentage of the PGMs as Rh and are lower in nickel and copper.

REO FLOTATION With a pioneering approach to Rare Earth Oxides (ROE), Axis House has developed specific reagents for the separation of ROE into mixed concentrates. BASE METAL SULPHIDE FLOTATION Axis House supply a range of selective Ore is processed using conventional techniques and differential flotation. Ore is passed to the primary crusher and crushed to 150mm. This is passed to the secondary and tertiary crushers and ground to 16mm. After milling the ore is fed into the flotation circuit. Following differential flotation zinc, lead and copper concentrates are produced.

The conventional process sequence involves smelting of a flotation concentrate to remove gangue material and to produce an iron-nickel-copper-PGM matte converting by blowing air through this matte to oxidize iron sulphide and to transfer the oxidized iron to the slag leaching the resulting copper-nickel-PGM matte to dissolve the copper and
Read MoreRidgeway Gold and Copper Mine, New South Wales - Mining Technology. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels. In 1984, Newmont sold the Okiep Copper Company to Goldfields of South Africa. More recently, assets from the Ookiep Copper Company were acquired by Metorex in 1998. Reprocessing of the slag dump over a seven-year period by flotation methods started in 2002.
Read MoreOre processing is planned to involve conventional differential froth flotation to produce separate copper and zinc concentrates at average grades of 24% Cu Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment.

In some cases, South African Jun 02, 2020 San Nicolas is planned to be operated through an open pit feeding a conventional flotation plant to produce zinc and copper concentrates. The decision to proceed is to be largely based on economics relating to the zinc price and Teck Resources requirement for zinc or zinc concentrate. The shown start-up date of 2023 is speculative at best.
