Features Of Electrolytic Manganese Flakes

Electrolytic manganese is a metal with the chemical symbol Mn, atomic number 25, and atomic weight 54.94. It is an off-white metal at room temperature and pressure, but it is easy to oxidize and turn black in the air. Electrolytic manganese is a relatively soft metal that has less hardness and strength than iron but more than copper. Electrolytic manganese has a melting point of 1,244 degrees Celsius and a boiling point of 2,061 degrees Celsius.

Electrolytic manganese enterprises not only bring GDP growth to the local area, but also bring serious environmental pollution problems, and the harm caused to the environment by the waste stored in the electrolytic manganese slag slag yard is also multifaceted, and the harm to the environment is manifested as:

(1) Manganese-dissolving slag is a waste residue produced by multiple presses, which is an extremely small particle. Moreover, the manganese slag still contains iron hydroxide colloids after a large amount of impurities, which makes it difficult to thoroughly filter the water in the electrolytic manganese slag, which is also a reason for the high moisture content of the electrolytic manganese slag. The residual soluble heavy metal ions mainly include ammonia nitrogen, manganese, mercury, arsenic, etc., which will enter the soil through the water cycle and further enter the biosphere and endanger humans.

(2) Nitrogen, ammonia and sulfate exceed the standard. Sampling and testing of surface, groundwater and river bottom sediments near an electrolytic manganese enterprise showed that the contents of nitrogen, ammonia and sulfate exceeded the standard, causing serious water pollution
