This chapter describes material and immaterial labour in the context of the industrial production, resource extraction, and global circulation of the silvery-alkali metal known as lithium. It focuses on the different kinds of material labour involved in lithium’s extraction from local sites in and around the Atacama Desert in Latin America, as well as less visible forms of labour underpinning the mining industry, including the labour of social reproduction and colonial dispossession. In this context, it asks: how do narrative arts document the violence of lithium’s extraction as it materialises in damaged and dispossessed bodies and environments, as well as those less visible traces of lithium’s circulation around the world, and the different affective economies it inhabits? I suggest that a contradiction or tension between materiality and immateriality, between what is seen and unseen, defines every level of lithium’s transformation into a commodity, as registered within global networks of labour. These larger systems, I argue, are rendered invisible; just as lithium silently provides the charge for iPhone and Tesla, it is a vanishing mediator to what some thinkers have described as ‘new extractive imperialism’. This, however, becomes visible—precisely as a kind of ideological dissimulation—across a whole range of narrative forms.
