Crushed and screened ore may be concentrated by washing, sink-float, jigging, tabling, flotation, dense media separation and high intensity magnetic separation to produce a saleable concentrate. Carbonate manganese ores may be calcined. Higher-quality fines may be agglomerated, nodulised, sintered or pelletised. Lower-quality ores, fines and …
Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature …
A new process for extracting gold from refractory gold ore and manganese from manganese anode slime was developed by combining the oxidative pretreatment of refractory gold ore and reductive leaching of manganese anode slime. The response surface methodology was used to optimize the effects of time, temperature, and sulfuric …
In this research, the coarse manganese concentrate was collected from a manganese ore concentrator in Tongren of China, and the contents of manganese and iron in coarse manganese concentrate were 28.63% and 18.65%, respectively. The majority of the minerals in coarse manganese concentrate occur in rhodochrosite, …
Making Sinter from Concentrate of Low-Grade Manganese Ore for Use in the Production of Ferrosilicomanganese
Magnetic separation is an effective strategy for the upgrading of a variety of lean ores, including the beneficiation of low-grade manganese ores. This work reviews 24 studies on the magnetic separation of manganese ores; 6 of these studies report both a sufficiently high Mn grade (>44% Mn) and Mn/Fe ratio (>7.5) in the concentrate as to be …
