This study reviews the use of sodium-based compounds such as urea, sodium sulfate, sodium chloride, sodium carbonate, and thiosulfate-often formulated with sodium cyanide-as gold leaching agents by artisanal miners, and proposes a greener, more sustainable alternative.This research further advances sustainable hydrometallurgy by developing and validating a glycine–thiosulfate hybrid leaching system as a non-toxic, cyanide- and mercury-free alternative for gold extraction.Glycine–thiosulfate systems can yield 70–90% gold recovery under optimized lab conditions. Effectiveness is ore-dependent (best for oxide and mildly refractory ores).Click: <a data-mce-href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5801183" href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5801183" data-mce-selected="inline-boundary">Continue Reading</a>&nbsp;

<h3>A survey measuring the ethanol levels in fruits consumed by chimpanzees suggests that these animals are regularly exposed to alcohol.</h3>Researchers from the University of California, Berkeley, conducted the first direct measurements of ethanol in fruits naturally available to chimpanzees across their African habitats. The findings suggest that the animals could ingest the equivalent of more than two standard alcoholic drinks per day through their fruit-based diet.In the U.S., a “standard drink” contains 14 grams of ethanol, regardless of the drinker’s size, while in much of Europe, the standard measurement is 10 grams.However, across all sites studied, male and female chimpanzees are consuming...<h3>Click: <a data-mce-href="https://scitechdaily.com/study-reveals-that-wild-chimps-consume-a-surprising-amount-of-alcohol-every-day/" href="https://scitechdaily.com/study-reveals-that-wild-chimps-consume-a-surprising-amount-of-alcohol-every-day/">Continue Reading</a></h3>#HealthAndEnvironment #PlantBasedWellness #PlantBasedWellness #BotanicalNutrition&nbsp;

Study Reveals That Wild Chimps Consume a Surprising Amount of Alcohol Every Day

Artisanal mining communities often rely on traditional methods for extracting precious metals. While these practices can provide essential livelihoods, they also pose significant health and environmental risks, particularly due to the use of mercury. Understanding the impact of mercury in these settings is crucial for both communities and policymakers.<figure id="figure-r1h6ynh5tsmifedvhn"><img id="r1h6ynh5tsmifedvhn" src="https://cdn.durable.co/blocks/1cZUnX5JlhEzn9kNqnq7NlTBliuthEtBvqVeYKIlBEjubtJqXMq1qCHFX6Vh2BWO.png" alt="artisanal mining" title="artisanal mining" class="object-cover bg-gray-100 " style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="null" data-positiony="null" data-fullwidth="false" data-mce-src="https://cdn.durable.co/blocks/1cZUnX5JlhEzn9kNqnq7NlTBliuthEtBvqVeYKIlBEjubtJqXMq1qCHFX6Vh2BWO.png" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h2>The Role of Mercury in Artisanal Mining</h2>Mercury is commonly used in artisanal gold mining to separate gold from ore. This process, known as amalgamation, involves mixing mercury with crushed ore to form a gold-mercury amalgam. The amalgam is then heated, vaporizing the mercury and leaving behind pure gold.While effective, this method exposes miners and their communities to mercury vapor, a potent neurotoxin. The health implications are severe, affecting the nervous, digestive, and immune systems, as well as causing developmental issues in children.<h3>Environmental Consequences</h3>The environmental impact of mercury in artisanal mining is profound. Mercury released into the air eventually settles into water bodies, where it can transform into methylmercury, a highly toxic compound. This contaminates fish and other aquatic life, impacting entire ecosystems and food chains.<figure id="figure-w3px3rkizdmifedvhn"><img id="w3px3rkizdmifedvhn" src="https://cdn.durable.co/blocks/8tYX5VnTJrdKNnaD4Z100sUwD52VKYpyP0utVMdDsYOUeytl1xpxOA234KfBDBS7.png" alt="mercury polluted water" title="mercury polluted water" class="object-cover bg-gray-100 " style="aspect-ratio: 3/2; object-position: 5% 10%;" data-corners="default" data-aspect="3:2" data-caption="Mercury Contaminated Waters" data-positionx="5%" data-positiony="10%" data-fullwidth="false" data-mce-src="https://cdn.durable.co/blocks/8tYX5VnTJrdKNnaD4Z100sUwD52VKYpyP0utVMdDsYOUeytl1xpxOA234KfBDBS7.png" data-mce-style="aspect-ratio: 3/2; object-position: 5% 10%;"><figcaption class="body-normal text-gray-500 mt-2">Mercury Contaminated Waters</figcaption></figure>Communities relying on these water sources for drinking, farming, and fishing are particularly at risk. Long-term exposure to mercury-contaminated water and food can lead to chronic health problems, further exacerbating poverty and health issues in these regions.<h3>Economic and Social Impacts</h3>Despite its dangers, mercury remains prevalent in artisanal mining due to its low cost and ease of use. However, the economic benefits are often short-lived. Health problems caused by mercury exposure can lead to reduced productivity and increased medical expenses, undermining the financial stability of these communities.Socially, the presence of mercury in mining communities can lead to increased tension. As awareness of its dangers grows, conflicts may arise between those who rely on mercury for their livelihood and those advocating for safer practices.<figure id="figure-nvwviqfmvmifedvhn"><img id="nvwviqfmvmifedvhn" src="https://cdn.durable.co/blocks/13fIFOJaNaMdxwqZtl7sVB6xc7aXuD0TdcS8irxkTvlBx7EvjvxWRmWDOtw7ZckB.png" alt="Slave Labor" title="Slave Labor" class="object-cover bg-gray-100 " style="aspect-ratio: 1/1; object-position: 0% 25%;" data-corners="default" data-aspect="1:1" data-caption="Children Mining for Gold" data-positionx="0%" data-positiony="25%" data-fullwidth="false" data-mce-src="https://cdn.durable.co/blocks/13fIFOJaNaMdxwqZtl7sVB6xc7aXuD0TdcS8irxkTvlBx7EvjvxWRmWDOtw7ZckB.png" data-mce-style="aspect-ratio: 1/1; object-position: 0% 25%;"><figcaption class="body-normal text-gray-500 mt-2">Children Mining for Gold</figcaption></figure><h2>Efforts to Mitigate Mercury Use</h2>International efforts, such as the Minamata Convention on Mercury, aim to reduce mercury use and emissions worldwide. For artisanal mining communities, this involves introducing safer alternatives and educating miners about the health risks associated with mercury.Organizations are working to implement mercury-free technologies and provide training on sustainable mining practices. These initiatives not only improve health outcomes but also promote environmental conservation and economic resilience.<h3>The Path Forward</h3>Addressing the impact of mercury on artisanal mining communities requires a multi-faceted approach. Governments, NGOs, and local leaders must collaborate to create policies that balance economic needs with health and environmental considerations.Empowering communities through education and access to resources is essential for fostering sustainable change. By reducing reliance on mercury, artisanal mining communities can work towards a healthier and more sustainable future.#SustainableMining #MercuryFreeGold #BiogenicLeaching #ResponsibleGold #ESGLeadership&nbsp;

The Impact of Mercury on Artisanal Mining Communities

<blockquote>In July, Peru’s then foreign minister Elmer Schialer said the illegal gold economy in Peru was seven times bigger than the cocaine trade.</blockquote>The Trump administration’s drone strikes against boats allegedly bringing illicit drugs to the US come amid an explosion in the amount of cocaine being produced in Colombia and Peru.But there is a new – and lethal – factor that is turbo-charging production – especially in Peru: the relationship between coca cultivation and illicit gold mining.<blockquote>Narco-mineria</blockquote>The nexus of coca cultivation and illicit gold mining is offering a swifter route to riches for criminal enterprises across the Amazon region – from Peru and Ecuador to Colombia and Venezuela. It’s known as narco-mineria, according to Collins.“Criminal organizations have found that illegal gold mining is a safer and more lucrative asset in which they can invest money from drug trafficking, and, in turn, launder the assets more easily,” according to Collyns, author of the forthcoming “Blood Gold: The Shocking True Story of the Amazon Gold Rush.”Click: <a data-mce-href="https://www.cnn.com/2025/11/22/americas/gold-mining-cocaine-traffickers-intl-latam" href="https://www.cnn.com/2025/11/22/americas/gold-mining-cocaine-traffickers-intl-latam">Continue Reading</a>#IllicitGoldMining #Cocaine #Cartel #AmazonGoldRush&nbsp;&nbsp;
