The arc round-trip acquisition path planning method is put forward, and the …

Abstract. This paper presents the life cycle assessment (LCA) carried out on the manganese beneficiation and refining process. This cradle-to-gate analysis is carried out using SimaPro software version 8.5. The considered case is the manganese beneficiation and refining process, and the final product is 1 kg of refined manganese.

Manganese is one of the leading mining pollutants. ... Many chemical methods are also used to recover Mn from hazardous chemicals in the environment such as immobilization, solidification, and vitrification [76]. The immobilization methodology is used to stabilize the heavy metals by treating in ex-situ and in-situ processes where the …
