Some 4,000 metres below the ocean surface, the abyssal ooze of the CCZ holds trillions of polymetallic nodules — potato-sized deposits loaded with copper, nickel, manganese and other precious ores.
Manganese in natural manganese ores mostly exists in the form of oxides, carbonates, and silicates. Manganese minerals with industrial value mainly include pyrolusite (MnO 2), psilomelane (mMnO·MnO 2 ·nH 2 O), manganite (Mn 2 O 3 ·H 2 O), braunite (Mn 2 O 3), and hausmannite (Mn 3 O 4), as well as rhodochrosite (MnCO 3) …

The undersea collecting vehicle is one of the three main parts in the deep-sea exploitation system. The Coandă effect-based collector picks up manganese nodules by providing an adverse pressure difference over the nodule, through the jet flowing around a curved wall. In order to overcome the drawbacks of repeated prototyping and …
In order to obtain higher wear resistance steel for the application in mining machines, new modified medium manganese austenitic steel (MMAS) was developed. The impact abrasive wear properties were investigated on MLD-10 impact wear test equipment. The wear resistant and strengthening mechanisms of MMAS were analysed by SEM, …
