Price of mercury rising faster than gold

By -
The price of mercury has has hit a new high of $1,850/flask (76lbs) or $53.67/kg and the gold:mercury price ratio has dropped to 840 - see www.mercurywatch.org

Some part of the mercury price increase is likely due to increased demand from Artisanal and Small Scale Gold Mining (ASGM), which is booming, along with the price in gold, and is now the world's largest demand for mercury. The forthcoming export bans by the EU (2011) and the US (2013), representing a future supply squeeze, may also be contributing to the price rise. The increase in the mercury price over the last year (almost tripling from $650/flask to $1,850/flask) has actually outpaced the rise in gold prices making the relative cost of using mercury to extract gold higher. The gold:mercury price ratio is an indicator of the relative cost of using mercury to extract gold.

Overall, the price increase makes mercury more expensive for uses, legal or illegal, and will, to some degree, be an incentive for increased conservation and recycling or switching to non-mercury alternatives. However, a higher price may also stimulate increased trade and production (legal and illegal) while significant demand exists. For marginalized Artisanal and Small Scale Gold Mining communities, an increased price will likely lead to increased conservation, recycling and alternatives where feasible, but can also have negative effects on their income and on the nature of their business relationships (more blackmarket, less ethical) - undesirable outcomes. For these communities a positive path forward is to minimize mercury demand (use) through access to better practices, policies, governance, and alternatives. Although there are some efforts to do this underway, they are few. 

It is interesting to consider what the price of mercury in the future will signify. Perhaps, ultimately, it will be an indicator of successful global management of mercury. If the demand for mercury is successfully reduced, the price, illegal trade, production, and emissions will all diminish. 

As well, It may be that for much of the world, reducing demand for mercury (and hence price) is a necessary prerequisite for effective collection and disposal of mercury already in circulation, mercury that will be recovered from contaminated sites and wastes such as mine tailings, and for preventing new virgin mercury production. If demand and price continue to rise, mercury that should be going to disposal sites may often be sold for use instead. The simultaneous ratcheting down of both supply and demand is therefore a requirement for successful management.

ASGM and Public Health

The AGC helps miners improve their productivity and helps them to comply with minimal health, safety and environmental standards; this can facilitate the formalisation of their livelihoods, allowing them to increase their income in a safer way for both them and their communities. One of the ways in which the AGC does this is through educating health workers and miners on the risks of certain aspects of ASGM and providing ways to mitigate these risks, while at the same time as training miners on how to process their gold in a safer way, largely by using less or no mercury.   For the vast majority of the millions of people who work in ASGM worldwide, labor conditions are substandard. There are multiple health risk factors that affect these populations; for example, acute accidents and injuries are common and chronic conditions resulting from exposure to toxins are prevalent, although rarely quantified. Moreover, ASGM communities typically have little to no access to education, ...

The Media's demonization of the Artisanal Gold Mining sector isn't helping

By -

The Miami Herald in 2018 and now Buzzfeed and the NYT in 2019 have published, once again, the typical easy story on alluvial gold mining in the Amazon: The very simplistic and oft repeated "mining is bad" story. They cast a pall over any and all that are involved in artisanal mining. What they report is not entirely untrue, but it is far from representative of the vast world of artisanal mining in the 82 countries where it occurs. Worse though, is that stories like this damage the fragile peace that has been obtained between governments and artisanal miners the world over during the last decade. The peace has been largely brokered by the UN and the OECD with their initiatives on mercury pollution (the Minamata Convention) and transparency (Due Diligence in the Gold Supply Chain). Mostly what the UN and OECD have championed though, is recognition of the huge development opportunity the artisanal gold mining sector represents. Helping the sector become a responsible one c...

Professionalization of the Artisanal Gold Mining Sector

Three professional mining engineers that have chosen to make careers in the artisanal gold mining sector and are busy helping to improve it onsite in Indonesia, 2019; left to right: Sixto Aguero, Abrar Ridhollah, and Yolanda Hantari. When asked what the Artisanal Gold Council’s mission is and about my own vision for the improvement of the artisanal gold mining sector, I explain that it is mainly two simple things. First, it is about the improvement of the artisanal gold mining sector writ large so that it can better perform its role in delivering development to the rural poor, essentially helping the sector to deliver the UN’s sustainable development goals (SDGs). And secondly, that the approach we use to do this, is professionalization, that we aim to professionalize the artisanal gold mining sector. In fact, professionalization of the artisanal and small-scale gold mining sector (ASGM) is largely what the Artisanal Gold Council does. To draw attention to this approach, I ...
