Synergising water and energy requirements to improve sustainability performance in mine tailings management

© 2016 Elsevier LtdMining is a water and energy intensive industry, and reducing water and energy consumption are two important issues in the quest for more sustainable industrial production. The aim of this paper is to assess the correlation between water and energy requirements in various tailings disposal strategies (on a per cent solids-based analysis). Two main methods are used: rheology testing and a system modelling approach. A coal mine site in Australia was chosen as a case study to apply five tailings disposal options. These five options are differentiated by the percentage of solids in the tailings ranging from 30% to 70%. The rheology analysis indicated that the coal mine tailings with 65–70% solids are not pumpable and these two options are beyond the scope of this study. The results of the analyses show that the optimal scheme process in terms of water saving, water management, and energy consumption involved tailings with 50% mass solids. The implementation of this option resulted in both lower water transport (15,532 ML/y) and energy consumption (34.7 TJ/y). This option also reduced the overall flows of water to the Tailings Storage Facility by 30%

Spiritual War: Revival, Child Prophesies, and a Battle Over Sorcery in Vanuatu

Sorcery and Christianity have been in an intimate and seemingly opposing relationship on the small Ahamb Island in Vanuatu for more than a century. While sorcery is seen as the most potent threat to the good life as it brings suffering and death, Christianity appears as the main tool to address this and other problems of cosmological and social character. During a turbulent time on the island in 2014, a Christian charismatic revival, largely led by children, became the subject of hope for change on Ahamb. A main event within the revival was a dramatic spiritual war that confronted the island community with the plain and unvarnished realities of good and evil, of God and sorcery, while revealing secrets that literally became a question of life and death
