The paper presents a comparison of the concentration methods conventional jig, air jig, and sensor-based sorting to treat construction and demolition waste. All tests were made with concrete, brick, and gypsum particles and the tests aim to separate these materials into different size ranges, depending on the method. The equipment tested, conventio...

This paper proposes pre-beneficiation studies by air jigs of the coal layers from a Moatize coal deposit. Pre-beneficiation, also called destoning, removes tailings before the beneficiation plant. The air jigs operate in the same granulometric size range as the heavy-media cyclones (HMCs) that are installed in the preparation plant. With the deston...

Large quantities of construction and demolition waste is generated annually around the world. Part of this material is processed in recycling plants. After removing metals, fines and lights, the construction and demolition waste is crushed and sized and can be used as aggregates for low resistance concrete, for road sub-base, city landfill and othe...

There are various patterns of construction and demolition waste (CDW) recycling plants combining different stages of the process like extraction of metallic elements and light elements, crushing, screening and clay flocculation. While most recycled plants have very simple processes and are hard to combine all the previous equipments, processes that...

La production des Déchets de Construction et de Démolition (DCD) peut combiner diverses opérations, telles l'élimination des éléments métalliques ou légers, le concassage, le criblage et la floculation des argiles. La plupart des plateformes de recyclage fonctionnent dans des configurations simples, sans faire appel à l'ensemble de ces techniques, ...

The purpose of this paper is to propose a sorting platform to increase the quality of recycled aggregates through the supplementary use of mineral processing techniques and additional sorting. The difficulty of liberation is discussed, and the methodology currently used in mineral processing is proposed. Jigs, hydrocyclones and sensor-based sorting...
