Image Processing of Manganese Nodules Based on Background 513 Therefore, it is difficult to restore the morphology of manganese nodules by using conventional image processing methods without affecting the gap between the manganese nodules. In a word, uneven illumination and morphological recovery of manganese nodules
Abstract In this paper, the possibility of processing zinc-manganese batteries in alkaline solutions is studied. It is shown that three-stage washing can remove potassium chloride from the active mass of milled batteries. The regularities of influence of some parameters (temperature, amount of alkali and number of cycles) on the extraction of zinc into solution …

Abstract— A hydrometallurgical method for the extraction and separation of Li(I), Mn(II), Al(III), and Fe(III) from the cathode material of a lithium–manganese battery is proposed for the first time; the method is based on a combination of leaching and liquid extraction using a deep eutectic solvent. The extraction system based on Aliquat 336/menthol (1 : 1) is used as a deep …
The environmental impacts of low-grade manganese ore processing are mainly related to gaseous emissions such as CO 2 and hazardous residue and waste disposal (Holappa 2010). Thus, in comparison with a process in which high-grade ores are being used, the considerable extra investment is required for rectification of the whole process where low ...

ABSTRACT This paper presents an innovative technology that has been developed for the smelting of Egyptian low-grade manganese ore to produce low-manganese pig iron and high-manganese slag. This produced slag has a high Mn/Fe ratio, which, therefore, can be used in a second smelting process in the production of manganese alloys. In this developed …

The effect of multivalent manganese doping on the defect structure is studied for the "lead-free" piezoelectric [Bi 0.5 Na 0.5]TiO 3 (BNT) by means of high-frequency electron paramagnetic resonance (EPR) spectroscopy. The results show that manganese is incorporated with di- and trivalent oxidation states on a titanium site, acting as an acceptor (Mn ′ Ti, Mn ′′ Ti).
The processes employed for solution concentration and purification in the hydrometallurgical processing of manganese include precipitation, cementation, solvent extraction and ion exchange. Solvent extraction also proves more efficient and it plays vital roles in the purification and separation of the manganese as compared to all other techniques.
