This study analyzes the reasons for the continued use of mercury in artisanal and small-scale gold mining (ASGM), highlighting the role of capital and the business model in driving the sector. Mercury plays a crucial role in this process and phasing it out remains a challenge.
Researchers and policymakers are concerned with the uncontrolled use of mercury in artisanal and small-scale gold mining (ASGM). Despite the availability of alternative technologies, mercury is still the first choice to separate gold from ore on most ASGM sites. Taking the case of Burkina Faso, this mixed methods study con-tributes to understanding the continued use of mercury by analyzing the non-technical functions that mercury accomplishes. Applying a political ecology lens, we analyze the mechanisms that actors deploy to access benefits from ASGM and manage business-related risks, revealing dependencies on webs of power that govern the informal setting of the ASGM value chain from production to export. Our results challenge conventional wisdom about poverty-driven ASGM. We demonstrate that the sector is not simply propelled by jobless rural youth and poor farmers eager to make a lucky strike. Instead, the need of ASGM for prefinancing extraction made it as much the product of capital looking for lucrative investment. The business model of investors is based on prefinancing extraction, controlling access to market, and taking advantage of excess labor by shifting operational and financial risks upstream. In an entirely informal scheme of cascading prefinancing arrangements, mercury serves as a 'commitment and controlling device.' The provision of mercury guarantees that the financier can access the gold at the exact moment of recovery, regain the loan, and secure the return on investment. Phasing out mercury will remain a challenge as long as it is used as a social control device.
