GlyCat™ enables substantial ESG benefits and reductions in processing costs by replacing the majority of cyanide with a non-toxic, food-grade reagent: Reduces sodium cyanide consumption by up to 90% depending on the ore type.
To understand the contamination caused by historic mining in California, researchers sampled sediment, water, and biota (animals) during the years 1999–2004 and 2011–2012. From the data collected, a set of interactive maps were produced. The maps, along with the data release and introductory video, explain the results of the research.
The mercury problem is a critical one. A paper from Flinders University found that between 410 and 1,400 tonnes of the element are emitted through artisanal and small-scale gold mining (ASGM)every year, with mercury-based ASGM causing more mercury pollution than any other human activity. While estimates vary, there are 15-20 million people working in the …
