Geo-tiles: manufacturing tiles from copper mine tailings using geopolymerisation
… feasibility of using aluminosilicate-rich mine waste, termed tailings, as the primary raw material to produce tiles using the low-energy geopolymerisation process. Traditional efforts to increase sustainability of ceramic tile manufacturing include waste valorisation to reduce virgin raw …

ESTABLISHMENT AND GROWTH OF ANNUAL AND PERENNIAL GRASSES ON COPPER MINE TAILING SLOPES (ARIZONA).
Research was conducted at Cyprus Pima Mine, an open pit copper mine located southwest of Tucson, Arizona, in 1980 and 1981 to study the establishment of annual and perennial grasses on the slopes of copper mine tailing ponds. In 1980, the north and south slope exposures were hydroseeded with barley …

Investigating the Genetic, Evolutionary, and Functional Mechanisms of Adaptations to Copper Mine Tailings in Mimulus guttatus
<p>The evolution of copper tolerance in the common yellow monkeyflower, Mimulus guttatus, is a classic example of rapid adaptation in plants; however, little is yet known about the genetic, functional, and evolutionary mechanisms involved. How does excess copper cause toxicity in M. guttatus, and …

Assessment of geotechnical considerations for ground control and stability at Nkana Synclinorium copper mine Mopani Plc, Zambia.
Nkana Synclinorium Mine is in the Southern part of the Nkana mining license area in Kitwe. The mine has been an underground operation since 1930 when the first shaft was sunk at Central Shaft. Vertical Crater Retreat (CVR) and Sub-Level Curving (SLC) are the main copper ore mining methods used at …

A technical and economic feasibility study on repurposing copper mine tailings via microbial induced calcium carbonate precipitation
… the sand aggregate used to grow bio-bricks with mine tailings. The increasing global demand for metal products has resulted in the concurrent production of vast volumes of waste mine tailings which, if left untreated, pose a potential risk of leaching toxins into surrounding populations and …

Ecological restoration of lead/zinc/copper mine tailings: Phytomanagement and amendment strategies to enhance substrate functionality and biomass production
“The extreme physiochemical characteristics of mine tailings inhibit microbial processes and natural plant growth. Consequently, vast and numerous tailings sites remain barren for decades and highly susceptible to wind and water erosion. Phytostabilization is a cost-effective and ecologically …

Electroanalysis of Cystine and Selenocystine.
… obtained as an industrial waste product from a copper mine, had been used; its similarity to tellurium had caused it to have been mistaken for that element. Since the name tellurium had been coined from talus, the Latin word for "earth," Berzelius named his discovery after the Greek word for …

Remote sensing analyses for open pit mine area computation. A comparative study on the implementation of multi-spectral classifications and crowdsourcing to compute the spatial extent of four open-pit mines in Indonesia, Australia, Canada and Brazil
… have already been conducted in the domain of mine detection and mapping, no comparative study has yet been carried out that investigates several remote sensing analyses, which are transferable to other geographic regions. The aim of this study is thus to compare remote sensing analyses that …

Constructing the aesthetic sense : traversing scales of habitation in the Bingham Canyon Mine
The activities of mining and mine reclamation in the American West raise questions of how we perceive, value, and differentiate between 'natural' and man-made landscapes, as they produce radical alterations of the land on a magnitude seldom seen. To many, the appearance of these sites is …

Characterization of Arsenic Hosting Phases in Subaqueous Tailings at Terra Mine, Northwest Territories, Canada
Over the lifetime of operations at Terra Mine, an abandoned silver-copper mine in the Northwest Territories, an estimated 500,000 tons of tailings containing 540,000kg of arsenic (As) were deposited into Ho-Hum Lake. Arsenic is being released from the tailings to the overlying surface water, …

A study of the flotation characteristics of a complex copper ore
Kansanshi copper mine is situated in the north western province of Zambia. Weathering has given rise to a vertically zoned profile comprising leached, refractory, oxide, mixed and hypogene sulphide mineralisation. As a result of the mineral variations, the processing plant treats three distinct ore …
