COPIOUS: A gold standard corpus of named entities

The paper describes in detail the construction of a gold standard named entity corpus for the biodiversity domain. An investigation of the performance of named entity recognition (NER) tools trained on the gold standard revealed that the corpus is sufficiently reliable and sizeable for both training and evaluation purposes.

Mining mainstreams biodiversity The Intelligent Miner

This is used to address the impact of extraction activities on biodiversity by working through a series of priorities for land use and commitments. The first priority is to avoid using sensitive areas of land altogether. However, if that is not possible, then the next priority is to identify measures to minimise impacts on the habitats or species within areas being used. The third priority

Global direct pressures on biodiversity by large-scale

15/09/2016· Gold and silver, often co-produced in the same mine, were chosen due to the high prevalence of gold (mostly open pit) (exploration and extraction) from areas of high biodiversity (especially from the mega-diversity zone) towards areas of lower biodiversity, reducing pressures on the former and contributing to minimizing drivers pushing biodiversity losses (i.e. one of the Strategic

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

The impact of gold mining and agricultural concessions

The price of gold has more than quadrupled since 2001 18, leading to increased rates of global extraction 19. Even small-scale, artisanal gold mining can have negative environmental and social impacts such as deforestation 7,20, water contamination 21, mass immigration and even the death of workers from metal poisoning 22.

Gold Mining Reinvented: Maximizing gold recovery

Gold extraction using cyanide was first introduced in 1880s. It is the most common and efficient method of extracting gold, especially for low-grade ore. The process involves treating the ore with

Green Synthesis of Gold and Silver Nanoparticles from

Biodiversity-rich countries need to collect and convert knowledge from biological resources into processes, compounds, methods, and tools, which need to be achieved along with sustainable use and exploitation of biological diversity. Therefore, this paper describes the relevant reported green synthesis of gold and silver nanoparticles from plant extracts and their capacity as antimicrobial

1. ENVIRONMENTAL IMPACTS OF GOLD MINING IN

Gold mining in Penhalonga represents all methods of gold extraction from deep underground mining, to small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these mining methods. It is a fact that whichever mining method, gold mining has environmental

The extraction of construction minerals and aggregates, in particular, represents the largest sub-sector of the NEEI industry with the EU in terms of value and volume. Securing reliable and undistorted access to raw materials is an increasingly important factor for the EU’s economic competitiveness. Recognising this, the European
