“…Our data show that formalization will not solve all of these problems. Other studies claim that among already-formalized ASM in mineral-rich countries, strengthening existing regulations is necessary to properly leverage improved livelihoods, and that this is in line with the case study presented (Weng et al, 2015). We also posit possible linkages between the large-scale mining and the ASM sector could benefit this process.…”

“…Mining can be a natural choice, as such work can be effectively conducted outside of the planting and harvesting seasons (Hilson & Pardie, A growing literature suggests that for many mining is an auxiliary activity employed to support other ends, rather than an attempt to 'get rich quick' (Hilson, 2010b). Although little evidence of this has been found in some areas, like Cameroon (Bakia, 2014;Weng et al, 2015), for some farmers in areas with mines, mining and mining-related activities generate income for agricultural inputs that will increase the value of their harvest (Cartier & Bürge, 2011;Maconachie & Binns, 2007). Others see mining as a means to accumulate capital to enter other-less physically risky-commercial ventures (Bryceson & Jønsson, 2010;Jønsson & Bryceson, 2009;Perks, 2011) or return to school (Cartier & Bürge, 2011).…”

This paper examines child labour in artisanal mining through ethnographic research in Tanzania. The poverty hypothesis argues that households send children to work to bolster household income. The sociocultural approach suggests that child mining offers valuable vocational training. This paper builds on a growing literature that complicates these approaches' straightforward claims by illustrating how household fragmentation is generated through the encounter of traditional cultural practices with mining's culture of consumption. This encounter exacerbates household fragmentation, which in turn increases child poverty and labour. These findings suggest that policy interventions should also address these mediating factors rather than poverty per se. Copyright © 2016 John Wiley & Sons, Ltd.

“…Since 2013, South Africa is the largest iron ore supplier in Africa with a ratio of two-thirds of total iron-ore production in Africa [2]. Moreover, the industrial mineral extraction processes used for mining activity are more developed in South Africa; although, studies have revealed that more than 12 million people in Sub-Saharan Africa depend on artisanal mining [7][8][9][10][11]. Most artisanal miners in some African countries use rudimentary techniques and tools without the required mining licenses [12,13].…”

Mine wastewater (MW) is often rich in heavy metals that can have measurable effects on humans. The storage and treatment of MW remains a challenge for most mining companies. Iron (Fe) in MW was removed by using extracts from Eucalyptus globulus (EG); Callistemon viminalis (CV); and Persea americana (AS). Fe was removed from MW samples with an initial concentration of 5.53 mg Fe mL−1; 4.63 mg Fe mL−1 and 4.40 mg Fe mL−1 using EG leaves, CV flowers and AS seed extracts, respectively. Conditions of the MW decontamination were studied by varying the dosage of the plant extracts, the temperature of the medium and the contact time between the MW and the plant extracts. Undiluted plant extracts—which were mixed with the MW and heated at 45 °C for 3 h—gave the highest Fe-removal efficiency for CV (70%) and AS (53%) extracts, respectively. Similarly, EG extracts, albeit heated at 25 °C, showed a higher Fe-removal efficiency (85%) than the CV and AS extracts at low to high temperatures. The residual Fe concentration in the MW was 0.83 mg Fe mL−1, 1.39 mg Fe mL−1 and 2.07 mg Fe mL−1 for EG, CV and AS extracts, respectively. Residue solid-phase deposits from the precipitation reaction of the MW with the plant extracts were collected and analyzed. Fe was among the byproducts detected in the deposited material. The characterization of the annealed solid-phase deposits revealed Fe precipitates as maghemite-C (Fe2O3) and magnetite (FeFe2O4) nanoparticles. Therefore, the MW quality and form were improved, making it reusable for other purposes.
