<blockquote><h3>A Review and Sustainable Alternative to Sodium-Based and Cyanide-Containing Gold Leaching Agents - Glycine – Thiosulfate Hybrid System.</h3></blockquote>Author: Bruce A. Cosgrove | Sustainable Technology eJournal | November 2025 |DOI:10.2139/ssrn.5801183.&nbsp;This study examines conventional sodium-based and cyanide-containing leaching systems used in artisanal mining, including urea, sodium sulfate, sodium chloride, sodium carbonate, and thiosulfate formulations. These methods remain widely adopted despite their environmental and toxicological risks. &nbsp;This research advances sustainable hydrometallurgy through the development of a glycine–thiosulfate hybrid leaching system, providing a non-toxic, cyanide- and mercury-free alternative for gold extraction. &nbsp;Under optimized laboratory conditions, glycine–thiosulfate systems achieve 70–90% gold recovery, with performance dependent on ore type, particularly oxide and mildly refractory ores. &nbsp;👉 These results demonstrate how <a data-mce-href="https://bruceacosgrove.com/mercury-free-botanical-extraction" href="https://bruceacosgrove.com/mercury-free-botanical-extraction">Plant-derived Extraction Chemistry</a>&nbsp;can be integrated into controlled hydrometallurgical processes for efficient and low-toxicity gold recovery → &nbsp;Full references and supporting research are provided in the complete article accessed here 👉 <a data-mce-href="https://bruceacosgrove.com/scientific-publications" href="https://bruceacosgrove.com/scientific-publications">A Review and Sustainable Alternative to Sodium-Based and Cyanide-Containing Gold Leaching Agents - Glycine – Thiosulfate Hybrid System</a>&nbsp;→### Scientific InterpretationThese observations reflect the application of botanical extraction systems, where plant-derived compounds interact with complex chemical environments to bind, mobilize, or remove target materials within processing systems.👉 <a data-mce-href="https://bruceacosgrove.com/botanical-systems-science" href="https://bruceacosgrove.com/botanical-systems-science">Biological Systems Framework</a> →&nbsp; 👉 <a data-mce-href="https://bruceacosgrove.com/scientific-publications" href="https://bruceacosgrove.com/scientific-publications">Technical Research Papers</a> →

Glycine–Thiosulfate Leaching: A Mercury and Cyanide-Free Approach to Gold Extraction

<blockquote>Global Air Quality 2025: Health and Environmental Implications &nbsp;</blockquote>The State of Global Air 2025 report highlights the scale and impact of air pollution on global health. An estimated 36% of the world’s population is exposed to PM2.5 levels exceeding 35 μg/m³, while nearly 2.6 billion people remain exposed to indoor pollution from burning solid fuels.&nbsp;&nbsp;Air pollution is a major driver of noncommunicable disease, contributing to conditions such as COPD, cardiovascular disease, diabetes, and neurodegenerative disorders. In 2023, approximately 86% of pollution-attributable deaths were linked to these chronic health conditions, particularly among adults over 60. &nbsp;👉 These patterns are best understood through applied <a href="https://bruceacosgrove.com/botanical-systems-science" data-mce-href="https://bruceacosgrove.com/botanical-systems-science">biological systems framework</a>, where environmental inputs and physiological responses are evaluated as integrated systems → &nbsp;The complete article can be accessed here 👉 <a data-mce-href="https://bruceacosgrove.com/blog-independent-referenced-articles" href="https://bruceacosgrove.com/blog-independent-referenced-articles">Global Air Quality 2025: Health and Environmental Implications&nbsp;</a>→### Scientific InterpretationThese observations reflect broader principles within botanical systems science, where compound interaction, biochemical pathways, and system-level biological response are evaluated as integrated systems rather than isolated variables.👉 <a data-mce-href="https://bruceacosgrove.com/botanical-systems-science" href="https://bruceacosgrove.com/botanical-systems-science">Structured Botanical Systems</a>&nbsp;→&nbsp; 👉 <a data-mce-href="https://bruceacosgrove.com/scientific-publications" href="https://bruceacosgrove.com/scientific-publications">Technical Research Papers</a> →

Global Air Quality 2025: Health and Environmental Implications

<blockquote><h3>The Impact of Mercury on Artisanal Mining Communities &nbsp;</h3></blockquote>By: Bruce A. Cosgrove, MSc. | Independent Scientific Researcher, Nov 25, 2025Artisanal gold mining relies heavily on mercury-based amalgamation, a process where mercury is mixed with crushed ore to bind gold, then heated to release the metal. While effective, this method exposes miners and surrounding communities to mercury vapor, a potent neurotoxin affecting neurological, immune, and developmental systems.&nbsp;Mercury contamination extends beyond immediate exposure. Once released, it enters air and water systems, where it is converted into methylmercury, a highly toxic compound that accumulates in aquatic ecosystems and food chains. Communities dependent on these resources face chronic exposure through drinking water and diet. &nbsp;Despite these risks, mercury remains widely used due to its low cost and accessibility. However, the long-term consequences—including reduced productivity, increased healthcare burden, and environmental degradation—undermine the economic stability of mining communities. &nbsp;Global initiatives such as the Minamata Convention aim to reduce mercury use, promoting safer alternatives and sustainable extraction methods. &nbsp;👉 These challenges highlight the need for <a data-mce-href="https://bruceacosgrove.com/mercury-free-botanical-extraction" href="https://bruceacosgrove.com/mercury-free-botanical-extraction">mercury-free extraction</a> capable of reducing toxic inputs while maintaining practical gold recovery processes → &nbsp;The path forward requires integrating safer chemical systems with education, policy, and local implementation strategies to support both environmental protection and economic resilience. &nbsp;### Scientific InterpretationThis analysis aligns with a broader botanical extraction systems framework, where plant-derived compounds are structured and applied to interact with chemical environments and remove, bind, or mobilize target materials.👉 <a data-mce-href="https://bruceacosgrove.com/botanical-systems-science" href="https://bruceacosgrove.com/botanical-systems-science">Plant Chemistry Systems&nbsp;</a> →&nbsp; 👉 <a data-mce-href="https://bruceacosgrove.com/scientific-publications" href="https://bruceacosgrove.com/scientific-publications">Peer Reviewed Work</a> →

Mercury Contamination in Small-Scale Mining: A Public Health Perspective

<blockquote><h3>Why Illegal Gold Mining is Overtaking Cocaine as the Drug Economy in Latin America &nbsp;</h3></blockquote>CNN World | By: Tim Lister &amp; Claudia Rebaza - November 22, 2025Illegal gold mining has emerged as a more stable and lucrative economic driver than cocaine trafficking in parts of Latin America. In Peru, the illegal gold economy is estimated to be significantly larger than the cocaine trade, reflecting a shift in how criminal organizations allocate capital and manage risk. &nbsp;Gold offers advantages over narcotics: it is easier to transport, less detectable, and can be integrated into legal markets through laundering and informal trade networks. Increasingly, illicit gold operations are linked to coca-producing regions, creating a hybrid economy where mining and drug trafficking reinforce each other. &nbsp;This expansion is driven by demand, weak regulation, and the continued reliance on low-cost extraction methods, including mercury-based processing, which enables rapid and decentralized gold recovery. &nbsp;👉 These dynamics highlight the need for b<a data-mce-href="https://bruceacosgrove.com/mercury-free-botanical-extraction" href="https://bruceacosgrove.com/mercury-free-botanical-extraction">otanical extraction systems</a> capable of reducing toxic inputs while maintaining viable recovery processes in resource-limited environments → &nbsp;The complete article can be accessed here 👉 <a data-mce-href="https://bruceacosgrove.com/blog-independent-referenced-articles" href="https://bruceacosgrove.com/blog-independent-referenced-articles">Why illegal gold mining is overtaking cocaine as the drug of choice for traffickers in Latin America</a> →### Scientific InterpretationThis analysis aligns with a broader botanical extraction systems framework, where plant-derived compounds are structured and applied to interact with chemical environments and remove, bind, or mobilize target materials.👉 <a data-mce-href="https://bruceacosgrove.com/botanical-systems-science" href="https://bruceacosgrove.com/botanical-systems-science">Systems-level Plant Chemistry</a>&nbsp;→&nbsp; 👉 <a data-mce-href="https://bruceacosgrove.com/scientific-publications" href="https://bruceacosgrove.com/scientific-publications">Scientific Publications</a> →
