Manganese extraction studies using ferrous sulfate and pickle liquor / By H. P. (Herbert P.) LeVan, L. S. Smith and E. G. (Edward George) Davis Abstract. Synthetic pickle liquor, g/l FeSO4/92 g/l H2 SO4, reacts in a similar way. (3) About 99% of manganese recovery can be obtained when reduced ore is treated with synthetic pickle liquor, containing g/l FeSO4 and 92 g/l H2 SO4. But this involves a costly reduction stage and carries a large amount of iron into the leach by: A rather novel process for recovery of manganese with pickle liquor (weak FeSO 4-H 2 SO 4-(NH 4) 2 SO 4 solutions) from low grade manganese ores was developed by US Bureau of Mine (Brantley and Rampacek ()).The process is schematically shown in Fig. process features the simultaneous high temperature hydrolysis of Fe(III) and precipitation of manganese as manganese Cited by: Synthesis of manganese zinc ferrite using ferrous pickle liquor and pyrolusite ore Article (PDF Available) in Environmental Chemistry Letters 9(2) February with 1, Reads.
1. Introduction. Manganese–silver ore, which has been found mainly in South-eastern U.S, Latin America (Presic and Wey, ) and China (Jiang, ), has attracted great attention for its importance as a mineral resource, not only for manganese, but also for recent years, many efforts have been made to develop efficient and economical process to recover manganese .

Experiments were carried out at room temperature to investigate the effect of pH on the extraction of manganese using M D2EHPA and M Cyanex in kerosene in the initial pH range The percentage extraction versus equilibrium pH plot [Fig.1] showed that the percent extraction of manganese increased with increasing.

Introduction. Manganese is widely used in steel production, nonferrous metallurgy, chemical industry, dietary additives, cells and fine chemicals, and other applications (Hazek et al., ).Hence, many efforts have been applied to develop an economic and efficient process to recover manganese from low-grade manganese oxide ores because the major manganese mineral in the ores is manganese.
