A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...

Silica refractory bricks are used especially in the metallurgical industries, due to desirable properties such as particularly their high melting point and their rigidity and strength at high temperatures. In this research, different amount of SiC were added to Silica refractory containing different binders such as Borax, Boric acid, Calcium nitride, Sodium tri poly phosphate, Sodium hexametaph...

Technological procedure of extracting metals is being constantly modernised so that polluting of the basic life resources is reduced. Emissions of waste gases and particulate matter are still present in larger mining-metallurgical complexes. Mining-metallurgical complex Bor (RTB) exploits sulphide copper ores, thus emitting acid sulphur gases and suspended particles with high content of Cu, Zn,...

This paper presents the results of testing possibility using limestone from "Međeđe" - Nikšić deposit in different industries. During examination, coarse moisture, chemical composition, granulometric bulk and particle density, degree whiteness, oil water absorption, composition micronized samples specific surface area were determined. All tests performed on 8 taken parts mean values obtained ar...

The estimation of metallurgical parameters of flotation process from froth visual features is the ultimate goal of a machine vision based control system. In this study, a batch flotation system was operated under different process conditions and metallurgical parameters and froth image data were determined simultaneously. Algorithms have been developed for measuring textural and physical froth ...

To attempt to optimize the anomalous phenomena that today go under the label "cold fusion" the experimentalist should be aware of the many aspects of the behavior of hydrogen in metals and of its entry into and egress from metals. This paper discusses the equilibrium characteristics of the isotopes of hydrogen in metals. The first section discusses the thermodynamics of the terminal solutions o...

The complexities that exist in the nature of the basic feedstock to the metallurgical process call for a high degree of ingenuity from the extractive metallurgist in seeking the best possible treatment method for a particular ore. Drawing from personal experience the author presents four case studies that demonstrate the value of creative thinking in addressing the challenges typically encounte...

Metallurgical accounting in the mineral processing industry transforms accumulated process data, including flow rates and assays, into a coherent information format. This is used to rapidly provide production reporting and key performance indications. Comprehensive and coherent data must be a component of any system expected to accomplish reconciliation in the mass-balancing process. Quality is...

Metallurgical activities have been undertaken in northern South America (NSA) for millennia. However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the timing of past metal depos...
