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...

The dewatering of flocculated high density slurry presents a significant challenge to most mining industries. new technologies treat require consistent and robust flocculation method in order enter the market tailings management. slurry, however, due its complexity, is always be undertaken appropriately evaluate performance correctly. This paper probes complexity by using torque-controlled mixi...

The article describes the main types of technological schemes for working out flooded strata sand deposits using hydraulic shovel excavators. analysis scientific and technical literature describing experience excavators in open-pit mining, including pits extraction construction sand, has been carried out. proposed scheme is that development reserves without preliminary water reduction by a exca...

Coal slurry is an essential component of mining operations, accounting for more than half operating costs. Dewatering technology simultaneously confronted with obstacles and possibilities, it may yet be improved as the crucial step reducing ultimate processing cost. Coagulation/flocculation used a dewatering process that reasonably cost-effective user-friendly. This paper reviews application di...

Belt filter presses represent an economical means to dewater the residual sludge generated in wastewater treatment plants. In order to assure maximal water removal, the raw sludge is mixed with a chemical conditioner prior to being fed into the belt filter press. When the conditioner is properly dosed, the sludge acquires a coarse texture, with space between flocs. This information was exploite...
