Based on a literature study and the identified main waste types, the potential of selected types of this waste for re-use was analyzed and prospective uses were proposed. Spatial context of mining waste production and distribution over a period of 7 years in Lower Silesia were analyzed and presented graphically. Concentrations of metals in Mitchell grasses were evaluated in terms of maximum allowable dietary levels in livestock. The 400-page volume is clearly driven by a didactical approach of the author. During the extraction of phosphate ore, the phosphate sludge is generated as a waste with huge amount.
This study demonstrates that large-scale invasion of rehabilitated mine sites by opportunistic, pioneering metallophytes like C. Pot trials demonstrate that Mitchell grasses are metal tolerant and have the ability to accumulate significant concentrations of metals Pb, Zn into their above-ground biomass. Das Buch eignet sich deshalb besonders, um Interessierten die Probleme der Erzbergbaureststoffe näher zu bringen. Over the gossans, the grass species Eriachne mucronata forma, Enneapogon lindleyanus and Paraneurachne muelleri replace the characteristic grass Triodia molesta where the soils have high Pb and Zn concentrations. In one of the regions the resource frame is made culturally resonant through the acknowledged expertise of scientists and industries that tie in with the region's history and daily experiences, while in the other region, the resource frame is weakened due to bitter memories of historical developments and contested knowledge claims.
KeywordsMine waste—Recycling—Mineralogy—Kyanite—Virginia This study was conducted to determine the metal Ag, Al, As, Cd, Co, Cu, Fe, Mn, Ni, Pb, Sb, Zn tolerance and uptake of Mitchell grasses when grown on waste rocks and tailings of a base metal mine, Australia. Several proposed biochemical hypotheses introduced here support selenium as the active constituent in context of Manna's glycoprotein content. This concluded biogeochemical factors such as specific local geogenic conditions combined with specific geological terrains contributed to Manna selenium mobility within specific Alhagi genera species, Apersarum boiss, A. In particular, earth science curriculums need to address land and water degradation as well as rehabili- tion issues. This is particularly helpful for undergraduate students in the Earth sciences and in mining engineering and related fields. The methodology of quantitative and spatial analysis used in this research can be applied to studies in other regions coping with the problem of a large amount of mining waste. Also, the growing imp- tance of the topics mine wastes, mine site pollution and mine site rehabilitation in universities, research organizations and industry requires a textbook suitable for undergraduate students.
These changes will enhance ore deposit discovery, mineral processing, and environmental management of ores and waste materials. Some of the slag remains on a waste dump and could contaminate the surrounding area through the dissolution of heavy metals and metalloids during weathering. Elements of environmental concern V, Cr, Ni, Cu, Zn, As, Ag, Sn, Sb, Ba, Hg, Tl, and Pb were detected; however, the concentrations of all elements except Ni were below that of the kyanite quartzites in the region from which the waste is derived. Since the last human interference three decades ago, the shrub Calotropis procera has colonised the rehabilitated Mary Kathleen uranium mine site, northwest Queensland, Australia. Whoever needs updated information on the mine wastes will welcome Lottermoser's book.
This well-illustrated second edition 1st ed. Although most of these terms are used loosely and interchangeably by various stakeholders, some of the short-and long-term benefits of recycling and re-use of mining and metal extraction wastes include Lottermoser, 2011 : 1 creating financial assets, 2 increasing resource efficiency by reducing the linear consumption of natural resources, 3 reducing waste production and accumulation, 4 encouraging innovation and growth of local industry spin-offs, 5 creating employment, and 6 shared responsibility and ownership over the environment. Significant research efforts are required to develop cost-effective reuse and recycling options and to prevent the migration of contaminants from rehabilitated waste repositories in the long term. The aim of this study was to investigate the effect of the calcination on the phosphate washing waste and its activation with alkali solution to produce geopolymeric mortars. In particular, earth science curriculums need to address land and water degradation as well as rehabili- tion issues. Es schließt eme wichtige Lücke.
This large amount of waste is one of the major problems which leads to severe environmental pollution and significant land occupation. We conceptualize valorization as a social process of framing in which the collective understanding of waste materials changes. This history is assumed to be a shared point of reference and a fundamental part of regional culture and traditions. These were from some 90 samples complied into 14 bulk samples, representing three regional centres of Iran. Artisanal metallurgical slag produced more than 50 years ago at a mine site in southwest Japan is rich in toxic metals and metalloids. All examined slags showed good potential for bioleaching of valuable elements.
An introductory textbook addressing the science of such wastes is not available to students despite the importance of the mineral industry as a resource, wealth and job provider. The results revealed that the microorganisms can catalyze metal extraction from slags as compared to leaching achieved under abiotic conditions. The application of phosphate amendments to tailings may represent an alternative strategy to limit the uptake of metals by Mitchell grasses. Then the obtained powders were activated with a solution of sodium hydroxide and sodium silicate. General readers; upper-division undergraduates through faculty.
Despite the environmental challenges associated with mining and metallurgical wastes, the mining and metal extraction industries can be integrated to form a circular economy model that promotes zero waste through the recycling and re-use of these waste materials. Until recently, undergraduate earth science courses tended to follow rather classical lines, focused on the teaching of palaeontology, cryst- lography, mineralogy, petrology, stratigraphy, sedimentology, structural geology, and ore deposit geology. The strong pedagogical framework is supported by case studies from around the world, end-of-chapter summaries as well as lists of resource materials and www sites for each waste type. The book emphasizes the characterization, prediction, monitoring, disposal and treatment as well as environmental impacts of problematic mine wastes. Many mine wastes do not contain or release contaminants, are inert or benign, and pose no environmental threat. In this article, we argue that the process of valorization that shifts material from the category of 'worthless' to the category of 'valuable' is a prerequisite for the making of secondary resources. The slag dumps represent long-term sources of metal pollutants, particularly of Zn, to local ground and surface waters.
