Review on Pit Lake Treatments

Abstract

It is reported that pit lakes formed after the closure of open pit mines around the world can become acidic leading to contamination of the local environment. According to the literature, it is strongly recommended that countermeasures based on predictions of water quality be required for better decision before the closure of open pits. One of the useful tools for prediction of water quality before mine closure is the method which integrates several models such as hydraulic, limnological and geochemical models. It could predict changes in parameters such as stratification, alkalinity, acidity, dissolved metals in a pit lakes over time and then be used for decision making and design of pit closure plans. Attempts have been made to prevent and remediate these acidic pit lakes, using filling of waste rock and water, bacterial sulfate reduction reactions and lime dosing systems.

“…GIS contains different commands that help users perform different discrete tasks, which is similar to word-processing software (Tanmoy Kumar Banerjee et al 2014;Yosoon Choi et al 2020). With the development of geographic information systems (GIS), this technology has been applied into the mineral industry (He et al 2012;Choi and Park 2011;Tsangaratos 2010;yosoon Choi et al 2020). Due to the implementation of "Digital Mine", a lot of mining companies and science institutes built the management information system for a large mineral resource (Craynon et al 2016;Pang Hui et al 2010).…”
