no
it is essential for steel making.

The most known mineral is pyrolusite - MnO2.
Pyrolusite is a manganese oxide mineral, that has yet to cause any fatalities. It could kill you if you grind it very fine and inhale it, or eat enough of it, or drop a block of it on your head, but other than that it's not much of a hazard to anybody.

Chlorine compounds have been important to humans for thousands of years. Ordinary table salt, for example, is sodium chloride (NaCl). Still, chlorine was not recognized as an element until 1774, when Scheele was studying the mineral pyrolusite. Pyrolusite consists primarily of manganese dioxide (MnO 2 ). Scheele mixed pyrolusite with hydrochloric acid (HCl), then called spiritus salis. He found that a greenish-yellow gas with a suffocating odor "most oppressive to the lungs" was released. The gas was chlorine.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
Something that is rust resistant will not rust easily; minor exposure to water will not cause it to rust. Something that is rust proof will not rust.
No they will not get rust they are not iron to get rust. only iron get rust.
Rust is a COMPOUND. rust is a element you stupid fool suk my prik
manganometry method is best method for phyrolosit ore . in manganometry test use sodium oxalat salt and potasium permanganat (for titration)
