In this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°C to 50°C. In the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. Effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...

A review of studies furnace processes in industrial furnaces has shown that there is a sufficient number for high-temperature and medium-temperature furnaces. However, an insufficient understanding low-temperature low-power One the most important factors working process ovens, contrast to significantly lower level temperature inhomogeneity. For example, heating ovens machine-building industry, ...

In this study, Bio-based carbon nanotubes (CNTs) have received considerable research attention due to their comparative advantages of high level stability, simplistic use, low toxicity and overall environmental friendliness. New potentials for improvement in heat transfer applications are presented due to their high aspect ratio, high thermal conductivity and special surface area. Phonons have ...
