Metal menace
Front end loader bucket teeth, rock bolts and even tools can find their way into the aggregate before entering transfer points, chutes and crushers. Magnets and metal detectors work together Metal detectors act as the "last line of defense" before the aggregate enters a critical stage of operation within the processing plant.

Assessment of Heavy Metal Pollution in Soils from Farms in …
This study revealed that soil in farms around Durumi rock quarry has heavy metals from both lithogenic and anthropogenic origins. The concentrations of total heavy metals in the soils were at moderate contamination levels and within WHO and FAO maximum allowable limits (mg/kg). This showed that the quarry activities did not lead to heavy metal ...

Heavy metal content and toxicity of mine and quarry soils
Purpose Soils formed in metallic mines and serpentinite quarries, among other unfavourable features, have high levels of heavy metals. They can release into the environment causing surface and subsurface water contamination, uptake by plants, their accumulation in the food chain and adverse effects on living organisms. In this work, we studied the magnitude of …
