1. Introduction. The relationship between mining and sustainability has been an area of growing interest in recent decades. Some papers have criticized the concept of "sustainable mining", alleging that it is sometimes used for the marketing and publicity purposes of mining companies (Kirsch, 2010; Whitmore, 2006).However, other authors …

The effects of phosphate mining on rhizosphere bacteria in surrounding vegetables and crops, including Lactuca sativa, Glycine max, and Triticum aestivum, are assessed in this study.As results, phosphate mining significantly increased the contents of some large elements, trace elements, and heavy metals in the surrounding agricultural …

This paper presents the environmental impacts caused by surface mining and the ecological rehabilitation of Haikou phosphate deposits, Kunming, China. Surface mining entails the removal of the overburden to expose bare rock surfaces, not only causing destruction of pre-existing vegetation, but also occupying large areas of land for …

Abstract. In modern geochemistry, phosphorus (P) is considered synonymous with phosphate (Pi) because Pi controls the growth of organisms as a limiting nutrient in …

Phosphate mining releases heavy metals into the surrounding environment. In this study, the effects of phosphate mining on rhizosphere soil fungi in surrounding crops, including Lactuca sativa var. angustata, Glycine max (L.) Merr., and Triticum aestivum L., were assessed. Phosphate mining significantly reduced the crop …

Florida's Phosphate MinesThere are 27 phosphate mines in Florida, covering more than 450,000 acres. Nine phosphate mines are currently active. Nine mines are 100 percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down. Phosphate mines typically range in size from approximately …

Diversity of Phosphate Chemical Forms in Soils and Their Contributions on Soil Microbial Community Structure Changes. ... screening microbes for P-solubilizing taxa from field soils (P-deficient soils, or P-rich soils in mining zones) ... due to a positive effect of low-P content on Acidobacteria. Further analysis at the lower family level, ...

The thinning vegetation and soil erosion problems left behind by extractive mining have caused serious environmental pollution, and vegetation restoration is one of the effective strategies to counter them. To study the effects of vegetation restoration on plant community species diversity, soil carbon, nitrogen and phosphorus, and the …

Phosphorus (P) is a vital element in biological molecules, and one of the main limiting elements for biomass production as plant-available P represents only a small fraction of total soil P. Increasing global food demand and modern agricultural consumption of P fertilizers could lead to excessive inputs of inorganic P in intensively managed …

Here we show that environmental and health life cycle impacts are often lower for phosphorus fertilizers sourced from secondary raw materials than for rock …

The mining industries produce phosphate rock with 28–31% of P 2 O 5 content. The phosphate ore is generally separated from the minerals of granges in different steps using several processes. After mining, the phosphate ore underwent a screening process on-site to separate the phosphate rock from the bulky mine wastes (on-site …

The positive effects of mining on the economy will also continue to spread, through its technology-driven practices and increased productivity measures. Innovations such as precise positioning technologies to allow exact drilling and extraction, slope monitoring and vehicle tracking for safety, and the use of autonomous vehicles will continue ...

The fertilizer raw material mining industry, as a sub-sector of the larger global mining industry, is not exempt from the prevailing social and political cli-mate. This publication …

Little is known about the changes in soil microbial phosphorus (P) cycling potential during terrestrial ecosystem management and restoration, although much research aims to enhance soil P cycling.

According to the reviewed results the major environmental impacts of phosphate mining and processing on the water resources were: impacts on the …

No effects relative to RP have been observed on freshwater and marine eutrophication for NB1, NB3, ... For the RP pathway, the rock phosphate extraction (mining) and long-distance transport from ...

Environmental aspects of phosphate and potash mining. This study explores a variety of approaches and techniques used by the fertilizer raw material mining …

In this report, the potential effects of marine phosphate (or any similar bulk sediment) mining operations on marine ecosystems in the Western Cape province of ... planned phosphate mining off the Namibian coast, has a dredging speed of 1–2 knots and drags an 11-m wide dredge head over the sea floor, cutting a trench that is up ...

Mineral Phosphate (Pi) is a finite resource, and without a proper understanding of the phosphorus (P) cycle and an effective P recovery program, this most basic and important nutrient for living organisms will be depleted. ... Although Phi is also formed by Pi entering the soil during the mining of P minerals, ... specific positive …

Mankind started mining for precious metals between 20,000 and 40,000 years ago. For the last century, mining has been one of our planet's largest industries (it generated 683 billion dollars in revenue in 2018 alone). This only underscores the fact that our desire for precious metals and minerals has grown exponentially since we first started digging through the …

Florida is the world's largest phosphate-producing area, according to the E.P.A., and accounts for about 80 percent of the nation's phosphate mining. The United States mines and consumes about ...

While there are some negative effects associated with mining, there are also several positive effects that are often overlooked. In this section, we'll explore 9 positive effects of mining on the economy, from job creation to increased tax revenues and more. So let's dive in and take a closer look at the benefits of this important industry. 1.

At the end of the xixth Century, Banaba was an unknown, and then 'unclaimed', island in the central Pacific; however, all was soon to change for its 450 residents. In 1900, a rock propping open a Sydney-office door of the Pacific Islands Phosphate Company was found to consist almost entirely of high-grade phosphate. It was soon traced back to the …
