Extensive tin mining activities produce sand piles with high silica, leaving vast environmental and economic responsibilities. The circular economy implementation can address these problems by valorizing quartz sand as industrial sand. Therefore, the study assesses the quartz sand left over from tin mining and processing activities on Bangka Island to become a valuable product within the CPQvA Framework consisting of classification (C), potential utilization (P), quantity and viability (Qv), and application (A). The criteria comprise 12 weighted questions to define the criticality indices categorized as easy, moderate, and difficult. With complex purification technology, quartz sand can be used as silica sand for ceramics, foundry mould, refractory bricks, glass, and solar cells. The quantity is large and feasible for a factory scale with expensive investment and operational costs. The product performance shows good quality from a technical aspect. Due to impurities content and its complex purification technology, the valorization of quartz sand produces a difficult criticality index for the solar cells, a moderate criticality index for the glass and ceramics industry, and an easy criticality index for the glaze, refractory brick, and foundry mold industries. Therefore, proven and efficient purification technology is crucial for further research.

This research aimed to determine the social, economic, and environmental impact of Saddang River sand mining on local communities and the Pinrang district government. Primary data collection used field surveys to obtain supporting data on economic aspects consisting of production capacity, costs, selling price of sand at the miner level and market price at the consumer level, number of grains, and various other economic values such as indirect value and indirect use value. The primary data collection method uses a total sampling of 80 miners operating in the research area. Consumer data uses a field survey method with 8 hours of observation per day. Saddang River sand mining provides great socio-economic value and environmental impact, directly or indirectly. This significant socio-economic value and impact, if not accompanied by good management, can result in over-exploitation, which impacts the physical and ecological damage of the Saddang River. On the other hand, the high rate of sedimentation from upstream of the Saddang River results in shallowing, so sand mining activities help normalize the Saddang River. Therefore, to continue providing economic benefits and the Saddang River to avoid physical and ecological damage due to mining activities, sustainable management of Saddang River sand mining is needed.
