Abstract

“Given the increasing scrutiny of the mining industry and its relatively poor record with regards to mine tailings management, increased requirements to minimise water usage (often accompanied by very high costs of water) and the need to demonstrate achievable long-term closure strategies, it is likely that the option of a filtered tailings system will need to be considered in many operations in future.” (Australian Centre for Geomechanics 2018). Given such a statement as a conference introduction, it is only appropriate that a range of potential technologies are investigated and compared, to create awareness for even underrated but appropriate technologies. The advantages and disadvantages of all technologies need to be considered and analysed. Suppliers are swift to promote their technologies advantages, however aspects of sustainability are not always fully understood and comprehended. Perhaps a combination of two filtration technologies is appropriate. This paper delves into the technical details, good or bad, of four mechanical dewatering technologies in tailings dewatering and provides insight on an undervalued and, in the author’s opinion, young technology – the screw press.
不受欢迎的尾矿脱水机械替代品:螺旋压机
“鉴于采矿业受到越来越多的审查,其在矿山尾矿管理方面的记录相对较差,对尽量减少用水的要求增加(通常伴随着非常高的水成本),以及需要证明可实现的长期关闭战略,未来的许多业务很可能需要考虑过滤尾矿系统的选择。(澳大利亚地质力学中心2018)。鉴于作为会议介绍的这样一种说法,调查和比较一系列潜在的技术是适当的,以便提高对甚至被低估但适当的技术的认识。所有技术的优缺点都需要考虑和分析。供应商迅速宣传其技术优势,然而,可持续性的各个方面并不总是得到充分理解和理解。也许两种过滤技术的结合是合适的。本文对四种机械脱水技术在尾矿脱水中的技术优缺点进行了深入探讨,并对一种被低估的、在作者看来是年轻的技术——螺旋压机提出了见解。
