A plant is under construction in the once-thriving copper-mining area of the Northern Cape that will make use of a new low-power South African-developed technology that is able to process stranded copper ore concentrates into 98%-pure copper crystals without the need for any smelting.
Oct 23, 2017 . Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it ... Although this technique is old, the process has to be operated by skilled workers and the facilities must have an excellent exhaust system in order to avoid.

The primary smelter and refinery plant uses concentrate as a raw material, produces copper cathodes, sulphuric acid, and precious metals, and discards slag and offgases.

The plant is operating at production rates above the original design capacity. Copper concentrate is smelted in an Outokumpu flash smelting furnace. Matte is granulated and processed using Kennecott-Outokumpu flash converting. Copper anodes are processed in a modernized copper refinery using the Kidd Process.
treatment and refining costs. There are other important advantages, such as the ability to treat low grade concentrates, bulk concentrates or concentrates with penalty elements. A number of variables that have been examined in the financial analysis including: - copper price. - plant capacity. - concentrate Cu grade.
Feb 1, 2011 . With Doe Run's new hydrometallurgical lead smelting process, a proprietary lead-bearing solution is exposed to an electric current, which electrowins the lead metal to cathode sheets. A similar electrowinning process is used to extract zinc from concentrate, but it has never before been applied to primary.
In 1992, an EPC contract for the turnkey expansion of the smelter and refinery with auxiliaries was delivered to increase capacity from 138,000Mtpa to 172,500Mtpa. Modifications to the oxygen plant and concentrate burner were made, as well as expansion of the main substation and oxygen pipeline to the converters.
from which a refractory oxide ore is mined for treatment by the segregation process in the Torco plant. The Group's predominantly sul- phide smelter-grade concentrates from all N.C.C.M's operations are treated at Rokana in what is prob- ably the world's largest copper- producing Rokana smelter. The Group's current annual.
35 – 1. 35 MINERAL PROCESSING PLANTS. Introduction. The following is a brief overview of the processes involved in mineral production in Ontario. During extraction and refining, the valuable metals are separated from the worthless materials by a series of physical and chemical operations. In Ontario the primary.
It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux. The silica flux binds with the . Sulfur dioxide gas from the flash furnace is captured and combined with water in an adjacent acid plant to produce sulfuric acid.The acid is sold as a.
Copper concentrate contains about 30% iron and the same percentage of sulfur content, but it also contains a small amount of precious metals, such as gold and silver, all of which are collected. In addition, in the Toyo plant, we use gold ore yielded from our Hishikari Mine (Kagoshima Prefecture) as solvent (silica) for.
This process is only one truly continuous process established in a commercial scale all over the world, which has a superior technology for copper smelting and converting. It is recognized as the most cost effective and environmental friendly process, and yielding anode copper directly from copper concentrate.
This development option results in the elimination of onerous costs for concentrate transportation and treatment. In Table 1 on page 3, the economics of a dedicated on-site. 50,000tpa-Cu Intec Copper Process plant are compared with the economics of treating a 28%5 Cu concentrate through a custom smelter at a tidewater.

Under the traditional smelting process, shown in Figure 2-1, the concentrate is shipped to the smelter, blended, dried, and fed to the smelting furnace.
Smelting is the process of separating the metal from impurities by heating the concentrate to a high temperature to cause the metal to melt. Smelting the .
