Introduction Dredging is a fundamental activity to ensure port navigability, sediment management, and the hydraulic safety of rivers, canals, and artificial basins. However, it also involves significant environmental impacts that require careful management and appropriate technologies. This article analyzes the main environmental issues related to dredging and illustrates the sustainable ...
This placement drives priming behavior, suction limitations, solids handling, maintenance accessibility, and overall system design in real world conditions such as slurry handling, dewatering, dredging, mining, and industrial transfers. The comparison below focuses on performance under load, typical application fit, and how system constraints drive the choice. ...
Introduction Colombia has high development potential for industrial, mining, and port dredging in South America. The mix of vast natural resources, growing infrastructure, and environmental awareness makes the country a strategic market for advanced slurry and abrasive material pumping technology. ...
Mining submersible pumps are specifically engineered to operate in submerged conditions, where other types of pumps would fail. They offer a solution to several challenges in mining, such as handling abrasive, corrosive, and sediment-heavy fluids. ...
These excavations often dump excess materials into nearby rivers, affecting aquatic life and water quality. Furthermore, the sediment from mining can carry dangerous toxins like mercury far downstream, putting both human health and natural ecosystems at risk. ...
Hydroman™ Submersible Agitator Slurry Pumps Applications: ▪ Pumping tailing slurry for industrial and mining organizations. ▪ Sucking silt in sedimentation basin. ▪ Pumping silty sand or fine sand for seashore or port. ▪ Pumping powdery iron ore for foreign countries, etc. ▪ Deliver a solid particles of mud, larger pulp, coal slurry, sandstone. ▪ Sucking ...
TSQ Submersible dredge pump mainly extracts liquids containing solid particles such as sand, cinder and tailing, and is mainly used for removing and transporting mud liquids in metallurgical, mining and thermal power plants. Submersible sediment pump is precisely cast with alloy material so it has the features of high quality and high wear resistance. ...
Abstract: Typical sedimentary sequences overlying coal seams consist of interbedded sandstones, siltstones, shales, and rider coal seams. In many surface coal mine settings, these sediments are saturated; and prior dewatering of them is necessary for effective and economic mining, including the stacking of saturated spoils. ...
The loss of the lake could also cause the loss of 7,000 jobs, and high-mercury mining waste in the lake’s sediment could cause an ecological nightmare if it becomes airborne dust. ...

The mining industry is a common source of environmental metal emissions, which cause long‐lasting effects in aquatic ecosystems. ...
The lake sediments are anoxic, characterized by reduced sulphur and sulphidic minerals. ...
As a result of long‐term metal mining and metallurgical activities, the sediment of Ross Lake (Flin Flin, MB, Canada) is highly contaminated with metals and other elements. ...
Sediment toxicity tests compared chronic effects on survival, growth, and biomass of juvenile freshwater mussels (28‐d exposures with Lampsilis siliquoidea) to responses of standard test organisms, amphipods (28‐d exposures with Hyalella azteca) and midges (10‐d exposures with Chironomus dilutus), in sediments from two lead‐zinc mining areas: ...
At the North River Mine approximately 1,000 gallons per minute is created on a 24-hour basis. ...
Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. ...
Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). ...
The fate of a currently halted deep-sea mining project in the Pacific is being watched closely by a number of parties. ...
Received for publication October 31, 2007. A legacy of lead and silver mining in its headwaters left Lake Coeur d'Alene, Idaho with a sediment body that is highly reduced and contains up to 100 g kg–1 iron and a smaller fraction of chemically active sulfide phases. ...
On April 25th 1998 a holding pool containing acid sludge from Aznalcóllar mine (owned by the Canadian-Swedish Company Boliden Ltd.) accidentally poured on the Guadiamar River (a tributary of the Guadalquivir River). Arround five million cubic meters of sludge polluted with heavy metals, mainly Zn, As, Pb, Cu and Cd (Blasco et al., ...
