Mineral water have a certain impact on the dry magnetic separators effect, especially for the fine-grained level separators are serious. Because the moisture will increase, "magnetic group" of adhesion, so that the "magnetic group" combined with a more solid and easy to stick to the drum skin, although increasing centrifugal force, can not be improved indicators, but sometimes worse. Therefore, when the rainy season when the water large ore, may be appropriate to increase the proportion of lump ore, the ore moisture, mud containing a relatively reduced amount of water a greater impact when selected sub-indicators, the operation to be taken to reduce the amount of ore and to guarantee access to qualified concentrate product approach to regulation. Coarse ore processing, when the water is less than 2%, for separators showed no significant effect; fine grade ore processing, water is less than 2.5% of the selected sub-indicators had no significant effect.
