What is the difference between geotextiles and geomembranes?
Geomembrane and geotextile are both used geotechnical materials. Because they are used geotechnical materials and waterproof materials and have many similarities, they are actually two completely different materials. 1.The difference in performance and use: The geomembrane is made of high-density polyethylene, which is used to prevent seepage, while the geotextile is made of non-woven fabric. ...

Importance of Dust Control Polymer For Mine Tailings
While separating the minerals from the ore, the residue is a concern for the environment. Tailings are the leftover material after the process. Mine tailings are toxic therefore are recommended to be kept away from the environment. While leaching, the chances are high that the toxic material might get into the water. It pollutes the streams and leads to destructive environmental conditions. The ...

Sequential extraction combined with isotopic analysis as a tool for studying lead contamination from mining activity
Tailings deposits generated from mining activities constitute a potential risk to the environment through leaching of potentially toxic elements hosted by a variety of minerals present in the mine-waste materials. In the present work, in an attempt to study the potential mobility of lead in different type of Pb-Zn ore concentrate residues and its environmental impact, a sequential extraction ...

Sulfide Tails Management Within the Framework of Sustainable Development in Mineral Sand Mines—The Case Study of Sierra Rutile Ltd.
The study discussed here assessed Sierra Rutile Ltd.’s (SRL’s) water-cover sulfide tails management method. Monthly and quarterly water samples from SRL’s Sulfide Tails Pond (STP), Total Tails Pond (TTP), and the Titan Domestic Pond (TDP) were analyzed for 15 months. Results indicated acceptable quality for the STP. From Student’s t-test analysis, it was found that the ...

Prevent tail gas pollution and reject environmental hazards
Motor vehicle exhaust is the exhaust gas generated during the operation of motor vehicles, including carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and solid suspended particles (PM), which is one of the culprits of air pollution. From the perspective of the current pollution situation, the vehicle exhaust emissions to a large extent exceed the self purification capacity of the ...

Uranium mining and milling: material security and risk assessment
At present, physical protection for the front end of the nuclear fuel cycle is typically at a significantly lower level than at any other part of the nuclear fuel cycle. However, in view of past experiences it is feasible to take into consideration some generic threat scenarios, potentially resulting in loss of control over the nuclear material, respectively its by-products, such as: illegal ...

The feasibility of non-water reaction polymer grouting technology application in seepage prevention for tailings reservoirs
Tailings reservoirs generally consist of a tailings dam, a tailings conveying system and a drainage system, which are indispensable facilities and provide security and environmental protection for storing tailings and clarifying water in some industries (e.g., metallurgy, non-ferrous building materials, nuclear and chemical industries). Consequently, consolidating seepage prevention and ...

Seven reasons to choose the X-MET8000 Expert Geo for mining
Mining companies are looking for ways to make their operations more efficient and reduce costs without compromising on product quality. Product Manager Christelle Petiot looks at how the X-MET8000 Expert Geo from Hitachi High-Tech can help them. When the Mining Indaba takes place this year, the topic of investment will top the agenda. After a decade of low demand and plunging commodity prices, ...

Gassy Ponds May Hold Key to Alberta`s Oil-Sands Emissions Battle
(Bloomberg) — Alberta's battle to reduce oil sands' greenhouse gas emissions is taking aim at one of the industry's biggest environmental bugaboos: tailings ponds. While producers have focused on curbing methane from drilling operations, the ponds, designed to hold residue from mining operations, are among the largest sources of emissions for oil-sands miners, said Eric Newell, a former ...

New study shows mining degrades waterways in 49 countries
A new study, led by Dartmouth researchers and published in Nature, reveals a distressing trend. Mining for gold and minerals close to rivers in the tropics is causing severe environmental damage in 49 countries. The research marks the first comprehensive investigation into how these mining activities are affecting river systems on a global scale, and the findings are alarming. The hidden cost ...

Titanium Corporation wants to green oilsands tailings while extracting value from waste
Managing tailings from oilsands mining operations is one the most vexing challenges facing developers as they work to improve their environmental performance. Simply put, tailings ponds are an eyesore and a greenhouse gas emitter and create air quality problems for nearby communities. Titanium Corporation, however, sees the tailings challenge as an opportunity, says company president and chief ...

Mine backfill
Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

Geotube Marine Technology Offers Custom Solutions for Unique Marine Applications Around the Globe - Case Study
Geotube units are fundamental for distinctive marine structures using proven, innovative methods and techniques. What does a Honduran mine debris dam have in common with an iconic cable-stayed bridge in Korea? Both structures were built using Geotube marine technology, an important component in the design of these projects. Geotube marine technology has proven successful in the creation of many ...

Tailings paste disposal – more than water recovery
The minerals industry has faced increasing pressures in recent years in the management of tailings streams. Environmental, economic and other factors have led many minerals producers to explore the technology of making and using “paste.” With the increasing number of installations worldwide, this technology has proved to not only be industry accepted, but economically advantageous. ...

Smooth and Textured HDPE Géomembrane for Mining Tailings Project DRC
HDPE Géomembrane liner is the widely used geosynthetic material for the anti-seepage lining projects in mines, ponds, dams, solid waste disposal sites and other industries projects because of its low permeability and strong corrosion resistance. BPM HDPE Géomembrane liner begins as raw polyethylene resin which is then processed into flexible HDPE liners. BPM HDPE ...

Less and More : Why You Should Pump Slurries with a Peristaltic Pump
LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a process slurry pump, ...

What do oil sands and shale gas have in common? Acute need for sustainable water management solutions
The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

The New Environmental Insurance Products: When Does it Make Sense to Buy Them?
Part One Introduction Real estate transactions with environmental problems often founder on attempts to shift the liabilities from one party to the other. In transactions with other types of problems, insurance is a popular risk transfer mechanism, and is regularly used for that purpose, but it is used far less often when there are environmental risks. This so-called 'environmental insurance ...
