Copper. In a plant that refines copper from sulphide ores, there is a great degree of distribution and concurrency in production. The unit processes of such plant are operated locally, but the material flows between the unit processes create dependencies. The most important unit processes of a plant may be, e.g. (Xxxxxxxxxxx et al., 2011, pp. 1-12):
1. Flash smelt furnace (FSF)
2. Xxxxxx-Xxxxx converters (PSC)
3. Anode furnace and casting (AF)
4. Electrorefining
5. Melting, casting Starting from unit process 1, each unit process provides the raw material for the next. Consequently, any processing-related shortcomings in a unit process may have adverse effects on the following phases. Besides, efficient production requires further coordination. The waste (or slag) from each phase requires further processing, because it still contains some copper. Thus, a slag cleaning furnace (SCF) or a slag concentrator may exist, or the slag may also be circulated back to FSF. Furthermore, some of the end products are harmful to the environment. Some heavy metals are generated from the ore, and the gases generated from each unit process contain, for instance, sulphur dioxide. To process sulphur dioxide, the plant has off-gas handling and ventilation systems connected to an acid plant to transform the sulphur dioxide to sulphuric acid. As the capacity of the acid plant is typically limited and, on the other hand, the emissions of sulphur dioxide should be minimised, the operation of the acid plant may restrict the execution of other aforementioned unit processes. Within COCOP, the document D2.3 System Requirements Specifications (2017) explains the requirements that are considered in particular. In the coordination of copper production, correct timing is essential. The execution of each unit process should be scheduled considering the entire plant. Event-driven operation is important, as changes in process states (such as start or end) may trigger or even hinder an operation. Still, due to slow process dynamics, the required resolution of response times is approximately one minute in most tasks. In comparison, some other production plants may require a timing accuracy of fractions of a second. In summary, the operation of a copper plant requires coordination with a plant-wide perspective. Thus, for optimal operation, each unit process should be operated within plant-wide constraints.

Copper. Dissolved copper concentrations in the AMD influent displayed large relative fluctuations with an average value and standard deviation of 0.037 ± 0.015mg/L Cu2+ overall. Dissolved Copper (mg/L Cu2+) Figure 32: Measured copper values (mg/L Cu2+) within the AMD influent and effluents of all reactors (R1-R6) over the course of the experiment. Significant removal of copper was exhibited in the limestone only reactor (R1) as an average of 0.017mg/L Cu2+ was recorded in the effluent which corresponded to 53.8% removal. In the biologic reactors (R2-R6) copper values dropped below detection (LOD = 3 μg/L) within the first month of operation. This trend continued for all biologic reactors (R2-R6) for the majority of the experiment (Figure 32). However, two large spikes in copper values during were recorded in January 2013 reaching values of 0.095 and 0.030 mg/L Cu2+ within Reactor 3 (30:70) and Reactor 4 (50:50), respectively. Still high copper removal percentages were characteristic of the bioreactors (R2-R6) with average removal percentages ranging from 67-92% throughout.
Copper. The JSE has introduced the listing of a Copper futures contract which is quoted in Rand and linked to the COMEX listed (a division of NYMEX) product on SAFEX. The listing programme will ensure that there are always two expires available for trade. The contract months to be listed are March, July, September and December. Copper has been mined for the past five thousand years and has become prolific in our lives and critical to the continuation of our world as we know it. It is the third most used metal after iron and aluminium and used in the production of bronze. The metal is currently used in a variety of base applications ranging from electrical wiring to cooking implements. Due to its predominant use in the base industrial economy it is often affected by cyclical economic factors as well as supply and demand. The SAFEX listed contract price is calculated using the USD price together with the ZAR forward points which translate into a ZAR price per ounce. One contract is equivalent to 2500 pounds with the price reflecting the price per pound.
Copper. (a) If XXX xxxxx copper concentrates, ore, or other copper-containing substances, then Gross Value shall be the value of the copper contained in the copper concentrates, ore, or other copper-containing substances determined by utilizing: (1) the mine weights and assays for such copper concentrates, ore, and other copper-containing substances; (2) a reasonable recovery rate for the refined copper recoverable from such concentrates, ore, and other copper-containing substances (which shall be adjusted annually to reflect the actual recovery rate of refined metal from such concentrates, ore, and other copper-containing substances); and (3) the Monthly Average Copper Price for the month in which the copper concentrates, ore, or other copper-containing substances were sold.
(b) If MAX produces copper cathode sheets tradeable in metal exchanges in New York (COMEX), London (London Metal Exchange), or Shanghai (Shanghai Futures Exchange), and if Section 1.3.3(a) above is not applicable, the copper cathode sheets shall be deemed to have been sold at the Quarterly Average Copper Price for the quarter in which it was refined. The Gross Value shall be determined by multiplying Copper Production during the calendar quarter by the Quarterly Average Copper Price.
