In over 80 developing countries in the world, mercury is the artisanal gold miner's go-to for separating gold from concentrated ore. Due to a lack of resources and available alternatives, mercury is often handled with bare hands, and in the effort to amalgamate gold, much of it escapes into waterways and soil where it enters the food chain.
Scalability: Ball mills can be scaled up or down to accommodate production requirements, making them suitable for both small-scale and large-scale operations. Energy Efficiency: The design and operation of ball mills allow for energy-efficient grinding, reducing energy consumption and operating costs.
