Circular economy implementation in the development of fire-retardant materials used in construction, industry, and general-purpose products
(Savez inženjera metalurgije Srbije, Beograd, 2022)
During a fire, passive fire protection systems are designed to prevent the spread of flames, smoke, and toxic gases. The new fire-retardant (FR) material, used for passive fire protection, is created by combining copolymers ...
Chalcopyrite leaching in acid media: a review
(Savez inženjera metalurgije Srbije, Beograd, 2020)
In the modern practice of copper production, more attention is increasingly being given to the possibility of treating low-percentage sulphide ores that cannot be treated with conventional procedures (crushing, grinding, ...
Review of the past, present, and future of the hydrometallurgical production of nickel and cobalt from lateritic ores
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Laterite ores are becoming the most important global source of nickel and cobalt. Pyrometallurgical processing of the laterites is still a dominant technology, but the share of nickel and cobalt produced by the application ...
Eco-friendly elderberry based sorbent for removing pb2+ ions from aqueous solutions
(Savez inženjera metalurgije Srbije, Beograd, 2022)
Elderberry (Sambucus nigra) pith was modified with polyethyleneimine (PEI) in order to improve the adsorption properties. Characterization of both dried Sambucus nigra pith (DSNP) and amino modification of elderberry pith ...
Investigation of the optimal technology for copper leaching from old flotation tailings of the copper mine Bor (Serbia)
(Savez inženjera metalurgije Srbije, Beograd, 2020)
This work aimed to investigate optimal leaching technology for copper extraction from old flotation tailings of the Copper Mine Bor. The leaching degree of copper after leaching with sulphuric acid at 80 degrees C was 50%, ...
Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand
(Savez inženjera metalurgije Srbije, Beograd, 2021)
In this study, the glass-composite was prepared using glass cullet and waste foundry sand as raw materials. The powder technology route was employed. The mixtures containing 10-50 wt% of the sand were sintered at T = 750 ...
