31 Citations | Cumulatively, the amount of copper in mine tailings generated by 2050 will equal the amount of contemporary in-use copper stock. |
51 Citations | These findings may inform future investigations into brass corrosion issues and plumbing designs. |
41 Citations | We find support for the price–theft hypothesis: Changes in the price of copper were positively associated with variations in the volume of “live” copper cable theft. |
23 Citations | The lead isotope analyses suggest different provenances of the raw materials used for making the brass objects, thus the different origins of the ores may hint that the brass wire and sheet were imported to the workshops in which the objects were manufactured. |
41 Citations | The theft of “live” copper cable is associated with fluctuations in copper price. |
| The large estimated copper resources along with evidence of slowing demand for copper over the long term considerably extend the time of “peak copper” and the long mine life of large deposits means the decline in production after will not be rapid. | |
| Copper extraction is distinctly profitable when the selling price of copper is ∼$2.5 per kg, whereas it is unprofitable when the selling price falls below $1.5 per kg. | |
| The results reveal that, financial speculation accentuated copper price moves during the last decade. | |
157 Citations | From the time of the King James Bible of 1611 in which all copper alloys are called “brass” irrespective of composition, the early development and use of brass has been confused, and learned books, both ancient and modern have often tended to increase rather than decrease this confusion! |
| Clearly, either of these processes could have supplied the starting material for the subsequent development of metal production leading to a casting technology, which is a highly significant step in the technical progress of metallurgy, whether of copper, brass, bronze or arsenical bronze. | |
| The results suggest that the archaeological brass artifact utilized alloy produced by a solid-state reduction process. | |
15 Citations | From the short-run and long-run causality tests, we determine that the futures market plays an important role in transmitting price information to other copper markets while such information flow is not found for the brass scrap market. |
| This study, therefore, provides new insights into price determination on the LME copper market, and resolves the ambiguity of previous research regarding the efficiency of that market. | |
13 Citations | All the examined gunmetal and brass artifacts contained 4–20 wt.% Zn, indicating that their alloys were originally manufactured by cementation, produced of recycled metal, probably due to economic considerations. |
64 Citations | Finally, it is concluded that the determined equation with 0.132 of RMSE can predict the copper price better than the classic estimation methods. |
86 Citations | Our analysis reveals that a significant proportion of future copper supply involves factors that are not immediately price-sensitive, and that a rapid unlocking of these ore bodies could have negative ramifications for economic growth, human development, and the transition to a low carbon future. |
| The results were compared with reference data for native copper and European trade copper and indicate that of the 17 copper samples in the suite, an archaeologically-unexpected high number of 12 were made of native copper. |
