“…The following figure shows a calculator that facilitates calculating the load of charge (Figure 3). [15] The application contains an interesting appendix describing the determination of process parameters and end properties in copper production [16,17]. You can find here not only information on the processes of alloying, refining or the machining process of a given material.…”

The study contains a description of the use of IT material base in foundry, refining and metallurgy processes. The program is an extension of applications for the assessment of physicochemical and refining properties of metallurgical slags and process base related to the production of brass. However, the functionality of this part is related to the assessment of the harmfulness of the use of specific substances in both laboratory and industrial processes. Thanks to the simple search interface, the user can get quick information about the dangers that can be carried by substances used by him. In addition, you can also check what protection measures should be used when working with the substances in question. The program also draws attention to the utilization of waste materials after production and research processes.

“…The previous studies [1][2][3][4][5][6][7][8][9][10][11][12] allow drawing the conclusion that there is a strong correlation between the nature of the ingots structure and formation of electron phases such as BCC β phase and HCP ε phase in the case of exceeding particular elements solubility limits [1][2][3]. It has been observed that formation of β and ε is complex due to mutual interactions between particular elements, which in turn make difficulties in its clear description and led to huge interpretation discrepancies presented in the literature [5][6][7][8][9][10][11][12].…”

Trial series of cast alloy MO59 obtained from qualified scrap was investigated. SEM and TEM of resulting precipitates were conducted. The SEM analysis demonstrated the dependence of silicon, phosphorus, iron, chromium and nickel in the composition of the so-called hard precipitates. TEM analysis showed the formation of phase AlFeSi and AlCr. Made studies have shown the important role of the composition of the batch melts brass CuZn39Pb2 type. The analysis of SEM and TEM resulting precipitates pointed to the formation of various forms of divisions, only one of which was described in the literature character of the so-called hard inclusions. The SEM studies demonstrated the dependence of the occurrence of inclusions rich in silicon, phosphorus, iron, chromium and nickel. In contrast, additional TEM analysis indicated the formation of AlFeSi phase type and AlCr. The results of the analyses referred to the structure of the batch. Due to the difficulty of obtaining recycled materials that do not contain these elements necessary to carry out further analyzes in the direction of defining the role of phosphorus in the formation of the so-called hard inclusions.

“…They are applied in conjunction with the enhancers of ionic reactions in slag and with fluxes correcting physical -chemical properties of slag. The main physicochemical benefits of the application of such substances rely on their interaction with a properly prepared -both in terms of composition and properties of surface -active agents -slag layer [16,17]. Such an approach is a novelty in the pyrometallurgy of copper and currently is the object of patent application [18].…”

The article presents an outline of the new technology of pyrometallurgical processing of slag in the direct-to-blister process. The analysis is based on the example of the production process of KGHM Polish Copper SA. A new way of implementing the technology of recovery of copper from the flash furnace slag by means of different feedstocks has been proposed. The method of controlling the processes is another innovation discussed in the paper. The presented concept intensify the reduction reactions, using the Carbo-N-Ox method, of copper compounds to forms of metallic phases in the slag. The processes of coagulation are accelerated and the processes crystallization of metallic phases are under control.Keywords: slag, decopperisation, reagents, recycling W artykule przedstawiono zarys nowej technologii pyrometalurgicznego przetwarzania żużli w procesie jednostadialnego otrzymywania miedzi. Zaproponowano nowy sposób realizacji technologii odzyskiwania miedzi z żużli z pieca zawiesinowego z zastosowaniem odmiennych materiałów wsadowych. Zaproponowano sposób sterowania procesami. Proponowana koncepcja prowadzi do intensyfikowania reakcje redukcji związków miedzi, metodą Carbo-N-Ox, do postaci faz metalicznych w żużlu. Przyspieszone też zostaną procesy koagulacji faz metalicznych. Zaproponowany został sposób analizy formowania się faz metalicznych w żużlu.
