Abstract The San Rafael mine in southern Peru produces over 10% of the world’s tin. decision was made to reprocess some its oldest tailings, due their volume and high tin concentrations. This tailing storage facility partially saturated required a dewatering process allow mining. paper describes conducted activities for this dewatering, including basic engineering studies focused on hydrogeolog...

Dewatering of sludge from sewage treatment plants is proving to be a significant challenge due to the large amounts of residual sludges generated annually. In recent years, research and development have focused on improving the dewatering process in order to reduce subsequent costs of sludge management and transport. To achieve this goal, it is necessary to establish reliable indices that refle...

One of the most critical aspects open pit mining is dewatering and mine drainage systems. The NCP Open Pit Gold Mine located in Central Kalimantan. This study area has a range rainfall intensities durations from moderate to heavy. Good required manage runoff water reduce entering front loading. used daily intensity data 1994 2018. Using Mononobe Method, hydrological for this were evaluated by d...

Abstract The valorization of phosphate mine waste (PMW) in different fields has recently become attractive to many researchers. This review paper examines the potential use PMW as a raw material applications toward sustainable management strategies. Dewatering, recovery and heavy metals, building materials ceramics have been captured this paper. Based on origin deposit treatment during ore bene...

The layout of the dewatering system in open-cast mining must be adapted to assumptions and size expected inflows, which, turn, depend on natural conditions operation other mines groundwater intakes, affecting arrangement hydrodynamic field. This case study analyses possible solutions related a change drainage system: decommissioning by flooding depleted deposit new one located vicinity. As part...

Dewatering of fine coal is a significant industrial challenge with economic and environmental implications. Due to the lack suitable dewatering technologies, particles are often discarded waste impoundments, leading substantial loss valuable natural resources while creating problems. The hydrophobic-hydrophilic separation (HHS) process unique solution this problem. In process, recyclable solven...

[1] New semianalytical solutions for evaluation of the drawdown near horizontal and slanted wells with finite length screens in unconfined aquifers are presented. These fully three-dimensional solutions consider instantaneous drainage or delayed yield and aquifer anisotropy. As a basis, solution for the drawdown created by a point source in a uniform anisotropic unconfined aquifer is derived in...
