Transformations in artisanal and small-scale gold mining
Historically, this type of mining has been the main economic activity of many municipalities in the Amazon region. As a result of mining, some municipalities have developed or even transformed culturally and demographically, such as Itaituba, Jacareacanga and Novo Progresso, which today concentrate in their territories most of Purpose Gold extraction in the Amazonian rainforest is accompanied by ecological threats and social grievances, but at the same time, the artisanal small-scale gold mining sector (ASGM) provides a livelihood for many people.

Mercury and artisanal and small-scale gold mining: Review
Artisanal and small-scale gold mining (ASGM) is present in over 80 countries, employing about 15 million miners and serving as source of livelihood for millions more. The sector is estimated to be the largest emitter of mercury globally. The Minamata Convention on Mercury seeks to reduce and, where feasible, eliminate mercury use in Small-scale gold mining in the Brazilian Amazon region has been discussed in a vast literature since the 1980s (Cleary, 1990, Hemming, 1978, Schmink and Wood, 2010). Like elsewhere, the majority of the studies focus on the legal, social, political, health and environmental aspects of mining (Hilson, 2002, Hinton et al., 2003, Sousa et Understanding small-scale gold mining practices: An

Formalizing artisanal and small-scale gold mining: A grand
The Minamata Convention mandates formalization of artisanal and small-scale gold mining to reduce mercury emissions and releases. In this article, we review the reasons why previous attempts to do this have largely failed, outline miner-centric approaches that are more likely to succeed, and estimate the likely costs of such approaches. We argue that The increase in the gold price over the past 10 years has stimulated small-scale gold mining in Africa, Asia, and South America, resulting in an annual production of around 400 tonnes of gold by roughly 16 million miners [].Despite the contribution of approximately 12% of total global gold production [], artisanal gold mining is known to have many negative Remote Sensing Free Full-Text Effects of Small-Scale Gold Mining

The lifeways of small-scale gold miners: Addressing
Ultimately, for the majority of small-scale gold miners getting by within inherently precarious circumstances, gold’s transformative potential is situated in personal lives and aspirations. It perpetuates a status quo that enables gold lifeways to carry on and those dependent on gold mining to continue.The general issue of artisanal and small-scale gold mining (ASGM) is conceptualized and examined in numerous works, including the contributions by Veiga (2009), Siegel and Veiga (2010), Saldarriaga-Isaza et al.

Gold losses and mercury recovery in artisanal gold mining
Introduction. Artisanal gold mining (AGM) is an important source of income in a developing, low-income region (Hentschel et al., 2003) such as the Brazilian Amazon due to the high Au concentration in the sediments of the river bottom (3–30 g/m 3)and in the layer of alluvial over-consolidated deposit called mocororô (up to35 g/m 3) (Bastos, Ultimately, the transformative potency of small-scale gold mining is located in personal lives and precarious dynamics rather than glittering promises of a sustainable future.
