Sep 08, 2018 · Their appliion in hydrometallurgy is much less known. Recently, Feng et al reported high recoveries of manganese from lowgrade pyrolusite ore in sulphuric acid using pyrolysispretreated sawdust as a reductant. A high manganese leaching efficiency was achieved with low iron extraction.
Manganese (Mn)
Manganese is a pinkinshgray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids. Appliions. Manganese is essential to iron and steel production.

About Lignosulfonates
Sep 09, 2019 · Lignosulfonates are extremely versatile and are used in a wide variety of industrial appliions. While generally associated with dust control and surface stabilization for roads, they are used as binders, dispersants, emulsifiers and sequestrants in a host of products such as gypsum board, animal feed pellets and micronutrient systems.
USA
A process for removing manganese and chloride ions from an aqueous acidic sulphate solution containing zinc, manganese and chloride ions without removing a substantial amount of zinc ions from the solution includes adjusting the free acidity of the solution if necessary to at least about molar. The solution is then treated with ozone to oxidize manganese ions to manganese dioxide, and the ...
