Abstract

Urban mining has emerged as a concept that goes beyond conventional recycling, as it aims to tackle both the challenges of solid waste generation and management, as well as the scarcity of primary resources. Gravity concentration has gained increasing attention as a promising method for addressing crucial challenges in urban mining applications. In this sense, this review provides a comprehensive and up-to-date overview of gravity concentration in urban mining processes, covering principles, techniques, current applications, recent advancements, challenges, and opportunities. Emphasis was placed on shifting from the commonly found literature focus on ore processing to solid waste processing. Three types of solid waste, namely plastics, construction and demolition waste (CDW), and waste from electrical and electronic equipment (WEEE), were chosen for a more in-depth examination due to their massive production and widespread generation. Discussions also considered the potential of gravity concentration to address the unique challenges in their processing and explored possibilities for future developments.

重力集中在城市采矿中的应用综述
城市采矿已经成为一个超越传统回收的概念,因为它旨在解决固体废物产生和管理的挑战,以及初级资源的稀缺。重力集中作为解决城市采矿应用中关键挑战的一种有前途的方法,越来越受到重视。从这个意义上说,本综述提供了城市采矿过程中重力集中的全面和最新概述,包括原理,技术,当前应用,最近的进展,挑战和机遇。重点放在从通常发现的文献集中于矿石处理转移到固体废物处理。三种固体废物,即塑料,建筑和拆除废物(CDW)和电气和电子设备废物(WEEE),被选中进行更深入的研究,因为它们的大量生产和广泛产生。讨论还考虑了重力浓缩的潜力,以解决其加工过程中的独特挑战,并探讨了未来发展的可能性。
