Magnetic Separation In The Mining Industry Mainland

Why magnetic separation matters for the mining industry. one of the greatest challenges facing the mining industry is the separation of unwanted material generated by the extraction process from the valuable material. mining, whether done through open seam or underground means, creates a huge amount of waste product in the form of worthless or low value minerals and unusable.

Avoid unnecessary handling and uninformed handlingassembly of magnets. avoid long term close bodily contact with strong magnets. keep strong magnets away from head, eyes, heart, and trunk. continuous daily exposure should not exceed 2,000 gauss or 0.2 tesla. maximum one off exposure should not exceed 20,000 gauss or 2 tesla.
