Steel shot is used in foundries as a means for mechanical cleaning of castings. Due to wear (mechanical damage) there is a change in size of shot. After some time of use steel shot it becomes unusable for shot blasting process and becomes waste. Studies have shown that this type of waste has good adsorption properties and it is suitable adsorbent f...

In the process of production of iron and steel substantial amounts of fuel and raw materials are consumed. Metallurgical coke as fuel, reducing agent and material that provide gas flow trough blast furnace processes must possess certain properties in terms of strength, due to expected changes in the conditions of high temperature environment. Deman...

This paper describes the analysis and rationalization of energy consumption in gray iron foundry CIMOS TMD Casting Zenica. Based on results of analysis the key points are defined rationalized and measures proposed to reduce energy consumption, and therefore reduce production costs. The most significant share of energy consumption, and therefore in ...

Opencast mines are a part of the systems with the worst influence on all environmental components (air, water, ground, flora and fauna). In the case that we completely left out safeguards, dust emission would have a significant impact on the health of employees and the local population. Dust emission from quarries belongs to fugitive emissions and ...

The study examined adsorption of Reactive Violet 5 (RV-5) textile dye from the aqueous environment on MFI zeolites as adsorbents at 283, 293 and 303 K. The reaction was observed on the original NH4ZSM-5 zeolite, a product of the Zeolyst International American company, and on the modified HZSM-5 zeolite. The concentration of dye before and after the...
