Digitalisation in mining refers to the use of computerised or digital devices or systems and digitised data that are to reduce costs,improve business productivity,and transform mining practices.However,it remains increasingly difficult for mining companies to decide which digital technologies are most relevant to their needs and individual mines.This paper provides an overview of digital technologies currently relevant to mining companies as presented and discussed by mining journals,the media and insight reports of leading consultancy agencies.Relevant technologies were systematically identified using text-mining techniques,and network analyses established the relations between significant technologies.Results demonstrated that currently 107 different digital technologies are pursued in the mining sector.Also,an analysis of the actual implementation of digital technologies in 158 active surface and underground mines reveals a limited uptake of digital technologies in general and that the uptake increases with the run-of-mine production.Large-scale mining operations appear to select and apply digital technologies suitable to their needs,whereas operations with lower production rates do not implement the currently available digital technologies to the same extent.These minor producers may require other digital transformation solutions tailored to their capabilities and needs and applicable to their scale of operations. 展开更多

澳大利亚东南部污水中的固态物质以有机和无机污染物负荷大、金含量高(在干物质中达2.35ppm)和钯/铂比率高为特征。引人注目的是其中某些浓度与目前作为金矿开采的地质矿床的浓度相近。全世界每年在污水中积累的各种金属可达几十万吨,... 澳大利亚东南部污水中的固态物质以有机和无机污染物负荷大、金含量高(在干物质中达2.35ppm)和钯/铂比率高为特征。引人注目的是其中某些浓度与目前作为金矿开采的地质矿床的浓度相近。全世界每年在污水中积累的各种金属可达几十万吨,其中包括360t的金。污泥通常被倾倒于陆地上或海洋里,因而污泥中的金属不断地被丢弃和释放到环境中。这种现象在污水海岸和海洋-河口系统中尤为突出。人类污水过度排放到近海区域,不仅对人类健康和近海渔业构成威胁,降低海岸带的娱乐使用价值,而且导致了人为贵金属沉积的形成。 展开更多
